  • Wifi disabled for Intel Centrino Wireless-N 1000 Intel in 12.04

    - by new_bie
    Laptop model - HP- dm4 - 2070. I had faced the same problem for wireless being disabled in case of 11.10. It had to do with the new kernel. I thought with 12.04 this problem will be handled but the problem persists. Is there no way to get the wireless working except for the way mentioned in the following link ??

  • kubuntu: wireless manager can't find any networks

    - by timuçin
    I just installed Kubuntu 12.10 and as I knew my wireless driver would not be recognized, I installed it manually through here. I suppose I shall mention that I also had to do this. The driver worked just fine until I restarted my system. Since then I can't even start over. My wireless card is realtek 8723 The oly lead I have is this piece of log: 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> wpa_supplicant started 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: starting -> ready 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): device state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42] 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <warn> Trying to remove a non-existant call id. 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: ready -> inactive 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs I feel really bad that I have been trying so many things and even while I am trying them I get a problem at every step. I am really frustrated. You can the time in the logs, I didn't get up early. Just needed to share my feelings. Even the ethernet cable I have use is short for God's sake, I have had to sit at this massively uncomfortable posture for hours. edit: I discovered something interesting. When I boot my windows I see that my wireless manager says "disconnected" now. However when I start ubuntu after windows and modprobe rtl8723e wireless works just fine. Then again, when I restart ubuntu I am back where I have started. So now I have to start windows, restart my machine and do the modprobe thing to see wireless networks.

  • Toshiba wireless is blocked

    I have the same problem, a 32 bits toshiba nb255, it first had the windows 7 bu next I installed the ubuntu 11.04. The wifi does not turn on. I used the following issues the commands rfkill unblock wlan0, sudo ifconfig wlan0 down; they were not able. by setting up the bios in advanced menu, the wireless communication sw in ON, but it did not work also. neither the utilities toshiba nor utilities of ubuntu (wicd, wifi radar). by using gedit to file group, nothing. by installing madwifi packet, nothing. by exporting the wifi driver from windows to ubuntu, by means of the NDISwrapper packet, neither.

Toshiba does not supply drivers or soft support for linux, marketing of course. I only see the device is up by protocols and down phisically, My question is, is it possible to enable or not shutdown physically the device?, because in the toshiba model nb255 the wifi is not set up/down bye means of a physical switch, but by means a combination of Fn + F8 (only for windows 7, no one more), Is there one possibility to configure the hot keys in ubuntu?

  • Wireless connection by using command screen

    I installed Ubuntu 12.04 armhf to my beagleboard-xm and now trying to connect to a wireless network.

  • Atheros wireless not working

    - by Chandru1
    I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working. So here is what i tried. First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0. Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results. Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it. For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830 I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help. ADDED: If anyone would like to know as to what drivers i am using this is the output. network description: Wireless interface product: AR2413 802.11bg NIC vendor: Atheros Communications Inc. physical id: 3 bus info: pci@0000:0a:03.0 logical name: wlan0 version: 01 serial: 00:19:7d:d3:0c:fd width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath5k driverversion=2.6.35-24-generic firmware=N/A latency=168 link=no maxlatency=28 mingnt=10 multicast=yes wireless=IEEE 802.11bg resources: irq:18 memory:d0000000-d000ffff Some more information and output as to what i have done. lsmod | grep ath ath5k 130083 0 mac80211 231541 1 ath5k ath 8153 1 ath5k cfg80211 144470 3 ath5k,mac80211,ath led_class 2633 1 ath5k

  • How to get Broadcom BCM 43XX Wireless card working

    - by Fer1805
    NOTE - Although this question is for a specific version of Ubuntu and a specific Broadcom model, the answer to it is for most Broadcom models and versions of Ubuntu 11.04, 11.10, 12.04 and 12.10. If you have come here from another question, feel free to read the answer instead. The answer covers many problems with several solutions. I'm having serious problems installing the Broadcom drivers for Ubuntu 11.04. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc. I was following the instructions on the following blog, with no luck. How can I get Broadcom BCM4311 Wireless working? Can someone help me? Edit: For the command: "lspci | grep Network", I get the following message: 06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) For the command: iwconfig, i get the following: lo no wireless extensions. eth0 no wireless extensions. When i follow the following steps (from the above link), there are a NO error message at all: open the 'Synaptic Package Manager' and search for bcm uninstall the bcm-kernel-source package make sure that the firmware-b43-installer and the b43-fwcutter packages are installed type into terminal: cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl' (you may want to copy this) and see if the term blacklist bcm43xx is there if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf put a # in front of the line: blacklist bcm43xx then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly). reboot 'End of procedure' Before (not ubuntu 11.04), if i wanted to connect wireles, i just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done. Now, the only options i see are: Wired Network Auto Eth0 Disconnect VPN Enable networking Connection information Edit connection. hope above info is enough for your help.

  • How do I install windows wireless driver for TP-Link TL-WN7200ND

    - by Jim
    I'm using the TP-Link TL-WN7200ND USB wireless adapter. I have downloaded the Windows drivers and updated Ubuntu to 10.10 by manually connecting the computer to the router. I also installed ndiswrapper-gtk. I get a Windows Wireless Drivers in my Administration menu, and I was able to get it to read the Windows 7 .inf file. The .inf for XP does not work. It adds it and the driver appears in the list with "Hardware: present". I set up the wireless connection information (ESSID and WPA2-Personal key). Problem: I don't see the network manager icon in the top right of the screen. I managed to manually start it manually using sudo services network-manager restart but it shows no connections in the menu, saying that there's nothing to manage. In my /etc/network/interfaces file I have an entry for the loopback and the standard two-liner for eth0 with dhcp. From memory, something like: iface eth0 auto eth0 dhcp I had read somewhere that 10.10 would have standard support for my wireless adapter (TL-WN7200ND) but that seems not to be the case. However, I don't ever remember having the network-manager icon in the top-right and it does not auto-start at the moment. This was originally an Ubuntu 9.10 install that I've upgraded over time. I also used to use pppoeconf to connect to the net, which might affect the /etc/network/interfaces file?

  • Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

    - by oyse
    I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card.

  • recent unreliable wireless connection with Netgear KWGR614 router

    - by gabkdlly
    Recently, my internet connection over wireless ( via a Netgear KWGR614 router ) has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista, nor on a Desktop running Windows 7 ( this machine is connected with an ethernet cable ). The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I know that this router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. Is it possible that someone is jamming my signal ?

  • Wireless on ThinkPad Edge E420s

    - by user21820
    I have installed Kubuntu 11.04 (Natty) on my ThinkPad Edge E420 laptop. Unfortunately, the wireless is not working. I have got Windows 7 installed besides Kubuntu, and wireless is working with no problems there, so it has to be problem of the OS. What I tried: I installed the official driver from Realtek RLT8192CE. After reboot the wireless didn't work, but at least the system was able to detect that it is present in the system. However, after executing lscpi -v, under the card's details there was a line "Currently used driver" which said "r8169". Why is this? I did all of this according to a manual on http://www.php-architect.com/blog/2010/05/01/getting-wireless-to-work-on-lenovo-thinkpad-t400-with-ubuntu-10-4-lucid/. There a meany other similar ones, but don't work for me either. My questions are: 1) Is there any way to get this fixed? If yes, how to do so? 2) Do you think OpenSUSE (or any other distro) is better distribution concerning such hardware issues, so should I give it a try? If yes, which distro gives me the best chance?

  • ifconfig can't see USB wireless

    - by Alex
    I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

  • Wireless connection disconnects and reconnects with a Netgear WNA1000

    - by William Berkenkamp
    Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard.

  • How to Install Broadcom Wireless Drivers (BCM43xx)

    - by Fer1805
    I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc. Edit: For the command: "lspci | grep Network", I get the following message: 06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) For the command: iwconfig, i get the following: lo no wireless extensions. eth0 no wireless extensions. When i follow the following steps (from the above link), there are a NO error message at all: open the 'Synaptic Package Manager' and search for bcm uninstall the bcm-kernel-source package make sure that the firmware-b43-installer and the b43-fwcutter packages are installed type into terminal: cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl' (you may want to copy this) and see if the term blacklist bcm43xx is there if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf put a # in front of the line: blacklist bcm43xx then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly). reboot 'End of procedure' Before (not ubuntu 11.04), if i wanted to connect wireles, i just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done. Now, the only options i see are: Wired Network Auto Eth0 Disconnect VPN Enable networking Connection information Edit connection. lspci -vnn | grep Network showed: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] hope above info is enough for your help.

  • Wake network adapter from deep sleep mode

    - by BeatMe
    I recently buyed a new Mainboard (Asrock ALiveXFire) and got some trouble with the network adapter. After switching my Windows 7 x64 in energey saving mode and returning from it, my network adapter couldn't be found. After some googling I found out, that apparently my network adapter has been put in a deep sleep mode and didn't reactivate. Their solution was to switch the PC off, take out the RAM and the CMOS battery for some time. After that, the adapter should be powered on again, but that didn't happen for me. I waited several hours before turning my PC on again, but that didn't help. Formatting and reinstalling didn't help either. The network adapter is not found in the hardware manager and reinstalling the drivers didn't help. I have the newest BIOS installed on the mainboard. I literally don't know what to try next. I'm thinking of returning my board, but I would like to avoid the hassle.

  • Wireless internet connection connects but internet does not work (no packets received). Wired does.

    - by Rodney
    When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang).

  • Computer Networks UNISA - Chap 8 &ndash; Wireless Networking

    - by MarkPearl
    After reading this section you should be able to Explain how nodes exchange wireless signals Identify potential obstacles to successful transmission and their repercussions, such as interference and reflection Understand WLAN architecture Specify the characteristics of popular WLAN transmission methods including 802.11 a/b/g/n Install and configure wireless access points and their clients Describe wireless MAN and WAN technologies, including 802.16 and satellite communications The Wireless Spectrum All wireless signals are carried through the air by electromagnetic waves. The wireless spectrum is a continuum of the electromagnetic waves used for data and voice communication. The wireless spectrum falls between 9KHZ and 300 GHZ. Characteristics of Wireless Transmission Antennas Each type of wireless service requires an antenna specifically designed for that service. The service’s specification determine the antenna’s power output, frequency, and radiation pattern. A directional antenna issues wireless signals along a single direction. An omnidirectional antenna issues and receives wireless signals with equal strength and clarity in all directions The geographical area that an antenna or wireless system can reach is known as its range Signal Propagation LOS (line of sight) uses the least amount of energy and results in the reception of the clearest possible signal. When there is an obstacle in the way, the signal may… pass through the object or be obsrobed by the object or may be subject to reflection, diffraction or scattering. Reflection – waves encounter an object and bounces off it. Diffraction – signal splits into secondary waves when it encounters an obstruction Scattering – is the diffusion or the reflection in multiple different directions of a signal Signal Degradation Fading occurs as a signal hits various objects. Because of fading, the strength of the signal that reaches the receiver is lower than the transmitted signal strength. The further a signal moves from its source, the weaker it gets (this is called attenuation) Signals are also affected by noise – the electromagnetic interference) Interference can distort and weaken a wireless signal in the same way that noise distorts and weakens a wired signal. Frequency Ranges Older wireless devices used the 2.4 GHZ band to send and receive signals. This had 11 communication channels that are unlicensed. Newer wireless devices can also use the 5 GHZ band which has 24 unlicensed bands Narrowband, Broadband, and Spread Spectrum Signals Narrowband – a transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies Broadband – uses a relatively wide band of the wireless spectrum and offers higher throughputs than narrowband technologies The use of multiple frequencies to transmit a signal is known as spread-spectrum technology. In other words a signal never stays continuously within one frequency range during its transmission. One specific implementation of spread spectrum is FHSS (frequency hoping spread spectrum). Another type is known as DSS (direct sequence spread spectrum) Fixed vs. Mobile Each type of wireless communication falls into one of two categories Fixed – the location of the transmitted and receiver do not move (results in energy saved because weaker signal strength is possible with directional antennas) Mobile – the location can change WLAN (Wireless LAN) Architecture There are two main types of arrangements Adhoc – data is sent directly between devices – good for small local devices Infrastructure mode – a wireless access point is placed centrally, that all devices connect with 802.11 WLANs The most popular wireless standards used on contemporary LANs are those developed by IEEE’s 802.11 committee. Over the years several distinct standards related to wireless networking have been released. Four of the best known standards are also referred to as Wi-Fi. They are…. 802.11b 802.11a 802.11g 802.11n These four standards share many characteristics. i.e. All 4 use half duplex signalling Follow the same access method Access Method 802.11 standards specify the use of CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to access a shared medium. Using CSMA/CA before a station begins to send data on an 802.11 network, it checks for existing wireless transmissions. If the source node detects no transmission activity on the network, it waits a brief period of time and then sends its transmission. If the source does detect activity, it waits a brief period of time before checking again. The destination node receives the transmission and, after verifying its accuracy, issues an acknowledgement (ACT) packet to the source. If the source receives the ACK it assumes the transmission was successful, – if it does not receive an ACK it assumes the transmission failed and sends it again. Association Two types of scanning… Active – station transmits a special frame, known as a prove, on all available channels within its frequency range. When an access point finds the probe frame, it issues a probe response. Passive – wireless station listens on all channels within its frequency range for a special signal, known as a beacon frame, issued from an access point – the beacon frame contains information necessary to connect to the point. Re-association occurs when a mobile user moves out of one access point’s range and into the range of another. Frames Read page 378 – 381 about frames and specific 802.11 protocols Bluetooth Networks Sony Ericson originally invented the Bluetooth technology in the early 1990s. In 1998 other manufacturers joined Ericsson in the Special Interest Group (SIG) whose aim was to refine and standardize the technology. Bluetooth was designed to be used on small networks composed of personal communications devices. It has become popular wireless technology for communicating among cellular telephones, phone headsets, etc. Wireless WANs and Internet Access Refer to pages 396 – 402 of the textbook for details.

    So, the short version of my sad story is that I tried upgrade Ubuntu to 12.04 and wireless driver has stopped working. I have tried all the solutions but nothing seem to be working. When I try to install my wireless from "Additional Drivers" Its says: Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log The lspci command gives me the following info about wireless: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) I have tried removing bcm drivers and reinstalling, but nothing seems to be working. rfkill is good too.

  • Wireless network unstable and often WPA2 protected networks just don't work

    - by Pedro
    I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.
