• Linux will not activate wireless after device has been re-enabled

  - by XHR

  Using a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again. However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this. This happens on all kinds of different distros including Ubuntu 9.10 Netbook, EeeBuntu 4 beta, Jolicloud and Ubuntu 10.04 Netbook. Edit I noticed this question is getting a lot of views. To give a quick update, I never did resolve this issue with the given distro's. However, I'm currently running Ubuntu 10.10 netbook edition and this issue has gone away.

• Hardware wireless switch has no effect after suspend and 13.10 upgrade

  - by blaineh

  This seems to be a fairly chronic problem, as shown by the following questions: How do I fix a "Wireless is disabled by hardware switch" error? Wireless disabled by hardware switch "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this? but no good solutions have been found! Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. All My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A ip=155.99.215.79 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. xev shows that no internal event is triggered for my wireless switch (f12), but other function keys also acting as hardware switches work fine. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. I just tried to reload bios defaults (or something) as shown by this video. Didn't work. Edit. I tried the contents of this answer, and it didn't work. Edit. I made a pastebin of dmesg. I couldn't even begin to understand the contents. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

• Wireless disconnects every 30 minutes

  - by Kez

  I have had a look through all the related questions and I get the feeling my problem is unique. My wireless connection disconnects every 30 minutes, for maybe 1 to 3 seconds. If I am browsing the web while it happens, I get the page cannot be displayed error message. I have checked the event logs as I was curious to know if there was anything in there. There is. Event 8033: BROWSER - The browser has forced an election on network \Device\NetBT_Tcpip_{B919CC30-25A9-45DD-A09F-549A6262FC9E} because a master browser was stopped. Reported exactly every 30 minutes which coincides with my wireless problem. I am running Windows 7 Ultimate, 32-bit. My wireless is Realtek RTL8187 integrated into a ASUS P5K-E/Wifi motherboard. It is on a workgroup and has never been on a domain. This problem does not affect any other computers. Wireless reception is great, and I have ensured that the wireless unit is transmitting on a frequency not used by any nearby wireless basestations. How can I fix this pesky problem?

• How do I create a WiFi hotspot sharing wireless internet connection (single adapter)?

  - by Ruppesh Nalwaya

  I know how to create a hotspot when connected to a wired network, but when I am using internet from a WiFi connection, this disconnects the wireless connection the moment I activate the hotspot. In Windows I can use Connectify Hotspot, which enables me to share the internet connection from the same wireless adapter as I am creating an access point on. As you can read on the technology overview page: Access Point mode allows you to create a hotspot using the same Wi-Fi card that you are using to access the Internet. How do I do this on Ubuntu?

• External WiFi Adapter for Eee PC 1000?

  - by Peter M

  I have an original Eee PC 1000 running the stock Xandros. I have run into problems where the internal WiFi card does not seem to have enough sensitivity to connect to a lot of access points. Although the computer will report APs in the area, unless the signal strength is over 80% (as reported by the Wireless networks application) I cannot seem get a connection. So is there a recommended USB WiFi adapter that is known to work with the Eee PC/Xandros system or in general with a Debian based system?

  - by luisfpg

  I have a Dell Vostro 3300, which has a Broadcom BCM4313 wireless. The point is that I cannot make it work in N mode. NetwotkManager applet says I'm on 54 Mbit/s.

• 12.04 drops Wired Network if Wireless connects

  - by mitt10tim

  This is a little different then most of the questions I have seen here. When I am at my office I keep my Lenovo Thinkpad t61p running Ubuntu 12.04 x64 connected via wired Ethernet. I also typically leave the wireless radios on. After a recent update the behavior of laptop in regards to the networks has changed. It used to be that if the laptop had a wired connection, the wired would supersede the wireless. Now, when I get to work and plug the laptop in and power it up, it connects via wired (correct behavior), shortly after the wireless begins searching for its favorite network (also correct) but as soon as it finds a network to connect to, I lose Internet. If I disconnect from the wireless network, leaving the wireless radios powered on, and refresh the wired connection, all is well again. Powering down the wireless radios also corrects the problem. How can I set this up so that the wired network (if available) always has precedence over the wireless?

• Internet access using Edimax BR-6204WG as NIC

  - by Mat Richardson

  My internet access at home is provided by Virgin Media via their superhub. I have a laptop with no NIC - however I do have a spare wireless router, the Edimax BR-6204WG, which I have been led to believe can be used to bridge wireless connections. Only problem is, I'm not sure how to go about doing this. The manual for the device is here:- http://www.edimax.co.uk/images/Image/manual/Wireless/BR-6204Wg/BR-6204Wg_Manual.pdf Basically, I want to be able to connect the Edimax wireless router to my laptop using ethernet cable and to use it to pick up the wireless connection from my Virgin superhub. I've managed to get so far in some ways, but then I'm stuck.

• What is causing my internet to be slow on one laptop but not the other and only at a distance?

  - by Matt Case

  I have a newer laptop, purchased within the last year (acer aspire 7740). This laptop does not have any problem connecting to wireless networks and indicates that the signal strength is excellent on most of the wireless networks I connect to. When the laptop is within 10 feet of my wireless router it gets 30 down 10 up. When it is farther away than 10 feet it will be lucky to get 3 down and 1 up. I also have an older laptop, purchased in 2005, that has no problems at all at the same range. None of my phones, gaming consoles or tablets have this problem. I am beginning to think that the problem must be some hardware defect with the wireless card. I can provide additional information if needed. Just thought I'd check to see what others thought because I've been working on computers my whole life and have never heard of this happening. I have also tried to change the channels on my wireless router and have had no success with this idea.

• Alfa AWUS036H USB wireless adapter not recognized

  - by GFiasco

  The Alfa AWUS036H USB wireless adapter will not be recognized by my netbook (Ubuntu 14.04, Asus X201E). As I understand it, the drivers should already be built in to this version of Linux, but I tried a make/make install of the latest Realtek drivers (as mentioned on How do I install drivers for the Alfa AWUS036H USB wireless adapter?) and it didn't work. I then followed the advice of this thread (ALFA AWUS036NH driver) and did a make/make install of the most up-to-date backport of the drivers, but that didn't work. At this point I tried a series of commands from this thread (http://ubuntuforums.org/showthread.php?t=2187780) in an attempt to identify the problem, but at no point could I get the laptop to ever recognize the USB adapter. I have also troubleshot the USB cable itself, tried both the USB 2.0 and 3.0 ports on the laptop, have never received an error message regarding a need to update the firmware, and have seemingly successfully installed all manner of variation of Realtek drivers which were supposed to make the adapter work. (I also tried to delete/clean up after each install, in the hope I wasn't making things worse.) Not sure what I should do next. Please let me know if I need to post any more information. Thanks very much for your help. EDIT: Before inserting Alpha USB adapter: :~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

• How do I get a Wireless N PCi card to connect to a wireless G router?

  - by Andy

  I'm having some problems setting up a new wireless PCI card on a WinXP SP3 PC. I know that the router is configured correctly. It is a Linksys WRT54GL, using 802.11b/g. Security mode is WPA2 Personal with TKIP+AES encryption. I am able to connect to this fine using my laptop (first gen MacBook with a 802.11b built in card). The new PCI card is also Linksys, but it supports 802.11n. Card seems to be installed ok (Windows sees it fine, doesn't list any errors in Device Manager), however when it scans for available wireless networks it can't find my wireless network (the router is set to broadcast the SSID). I tried to enter the network SSID manually, but that didn't seem to help. I chose WPA2-PSK for network authentication. The only options for encryption are TKIP or AES - I've tried both, neither worked. I am sure that I typed in my wireless key correctly. At this point, I don't think the problem is with encryption, but something else. It almost seems like I need to switch the wireless card into g mode, but I haven't found a way to do that (if that is even possible/necessary - I thought n was fully backwards compatible with g). Also, the PC is in the same room as the router, and my laptop, so I don't think that it is an interference issue. Any ideas what I'm doing wrong? I'm running out of things to try at this point. :(

• Wireless Repeating with two Netgear N750 (WNDR4300)

  - by jomo1911

  I have a Netgear N750 as my main router, which connects to the internet via a modem. I have a second Netgear N750 which I want to use to repeat the wireless signal of the main router. I logged in to routerlogin of my main router (192.168.1.1) and set up the "Wireless Repeating Function". I set it as the "Wireless Base Station" and filled in the MAC adress of my second Netgear N750. Then I logged in to routerlogin of my second router and set it up as the "Wireless Repeater", I gave it the IP 192.168.1.11 and filled in the MAC adress of the base station. During the setup of the second router (Repeater) I had to disable all security functions. If I connect to the repeaters' WLAN signal, I get no internet connection. Maybe you can help me, thanks

• Fedora 12 Wireless problems (Intel Wireless 4965AGN Card)

  - by Ninefingers

  Hi All, I'm having an interesting experience with my wireless card at the moment. Basically, it does like this: I connect to the local wireless network (netgear router) It works, briefly, allowing me to browse a webpage or maybe two, if I'm lucky. It then stops working / sending any packets, whilst reported still connected. Now, me being me I've had a look to see what I can find. wpa_supplicant.log looks like this: Trying to associate with valid_mac:a2:30 (SSID='vennardwireless' freq=2462 MHz) Associated with valid_mac:a2:30 WPA: Key negotiation completed with valid_mac:a2:30 [PTK=CCMP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to valid_mac:a2:30 completed (reauth) [id=0 id_str=] CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys So that's working fine. dmesg | grep "*iwl*" spits out this: iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds iwlagn: Copyright(c) 2003-2009 Intel Corporation iwlagn 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:03:00.0: setting latency timer to 64 iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 iwlagn 0000:03:00.0: Tunable channels: 13 802.11bg, 19 802.11a channels iwlagn 0000:03:00.0: irq 32 for MSI/MSI-X phy0: Selected rate control algorithm 'iwl-agn-rs' iwlagn 0000:03:00.0: firmware: requesting iwlwifi-4965-2.ucode iwlagn 0000:03:00.0: loaded firmware version 228.61.2.24 Registered led device: iwl-phy0::radio Registered led device: iwl-phy0::assoc Registered led device: iwl-phy0::RX Registered led device: iwl-phy0::TX iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 So that's working too. I can also ping 192.168.0.1 -I wlan0 and arping 192.168.0.1 -I wlan0 the router until the network falls over. uname -r:2.6.32.10-90.fc12.x86_64. Laptop is a Core2 Duo (2Ghz) with 3GB RAM. Other symptoms I've noticed are that wireshark freezes when I capture on the "broken" interface until I disconnect. Am using networkmanager as per normal. Stupidly, I can connect to the same router via eth0/a cat6 cable just fine. Everyone else can connect to the AP fine (from Windows). Yes, I'm sat right next to it and not trying to access a hotspot the other side of the world. Any ideas? Is this a broken update? (I intend to reboot and test an older kernel later)? Anyone else come across this? Edit: iwconfig wlan0 rate auto is the settings I'm using for rates. Also, according to networkmanager the network is still connected. Thanks for any pointers / advice.

  I've had Ubuntu installed on my HD for about 3 months but ever since I ran into this wireless issue I kinda lost my lust of Ubuntu. I have zero experience getting around with/ using the console command. I have a Lenovo V570. I got the driver update for the broadcom networking card via the Additional Drivers application but that did nothing. I love the look and feel of using Ubuntu but I have no technological experience for the matter. Any help would be awesome. When I scan for wireless connections while in Ubuntu, my computer picks up nothing, while on Win7 it will pick up the handful of wireless networks around my area. My wired connection is fine, but the use of not having wireless on a laptop is rather contradictory to it as a feature. Cheers! Also, I just installed 11.10, if that helps any. Yes, I used the search before I posted this, but again I have ZERO understanding of the command stuff and need a meat and potatoes answer(s). stephen@ubuntu:~$ sudo lshw -class network [sudo] password for stephen: *-network UNCLAIMED description: Network controller product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f1900000-f1903fff *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:04:00.0 logical name: eth0 version: 06 serial: f0:de:f1:63:98:14 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168e-2.fw ip=192.168.1.78 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:41 ioport:2000(size=256) memory:f1804000-f1804fff memory:f1800000-f1803fff stephen@ubuntu:~$ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no

• Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

  - by Grand Master T

  Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?
