• Wireless doesn't work on a Lenovo V570

  - by Stephen

  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

• Bluetooth mouse Logitech M555b not recognized on a Macbook Pro 8.2

  - by Pierre

  I just bought a Logitech M555b Bluetooth mouse today. My computer (a Macbook Pro 8,2) has a bluetooth connection, and it works perfectly fine on Mac OSX (I set up a new device, click the connect button on the mouse, and voilà, done in 5 seconds). I cannot get it to work on Ubuntu 12.04. When I follow the same steps as on Mac OSX under Ubuntu 12.04, Sometimes I will see the mouse name appearing for 1 second on the screen, and if I'm fast enough to click on "Continue", I will have a message telling me the pairing with my mouse failed. Here are the steps I follow: Turn off Bluetooth on Ubuntu Turn Bluetooth on. Bluetooth icon Set up new device... Turn on the mouse, and press the Connect button. Press "Continue" on the Bluetooth New Device Setup screen I see the mouse name for one second, but then it disappear. Click on PIN options... to select '0000'. ... nothing, Ubuntu won't see anything. In the /var/log/syslog, I have the following information: May 27 23:26:16 Trane bluetoothd[896]: HCI dev 0 down May 27 23:26:16 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been disabled May 27 23:26:58 Trane bluetoothd[896]: HCI dev 0 up May 27 23:26:58 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been enabled May 27 23:26:58 Trane bluetoothd[896]: Inquiry Cancel Failed with status 0x12 May 27 23:28:26 Trane bluetoothd[896]: Refusing input device connect: No such file or directory (2) May 27 23:28:26 Trane bluetoothd[896]: Refusing connection from 00:1F:20:24:15:3D: setup in progress May 27 23:28:26 Trane bluetoothd[896]: Discovery session 0x7f3409ab5b70 with :1.84 activated I tried for an hour, I restarted my computer, re-paired the mouse on Mac OSX, etc. Sometimes when I restart the computer, I have a dialog box showing up saying that the mouse M555b wants to access some resources or something, if I click "Grant", or even if I tick "always grant access", nothing happens... How can I get the Bluetooth to work properly? Help!

• 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?

• USB mouse pointer only moving horizontally on macbook 6.2 with 12.04

  - by Glyn Normington

  After installing Ubuntu 12.04 on a macbook pro 6.2, the touchpad and external USB mouse worked perfectly. After rebooting I can't get either touchpad or external USB mouse to work. Sometimes no mouse pointer is visible, but more often I can only move the mouse pointer horizontally five sixths of the way across the display (from the top left). I have uninstalled mouseemu. xinput list shows the USB mouse. xinput query-state for the USB mouse shows the following: ButtonClass button[1]=up ... button[16]=up ValuatorClass Mode=Relative Proximity=In valuator[0]=480 valuator[1]=2400 valuator[2]=0 valuator[3]=3 and re-issuing this command with the pointer at its right hand extreme displays the same except for: valuator[0]=1679 So the valuator[0] seems to be the x-coordinate of the pointer and the range of motion 480-1679 is indeed about five sixths of the display width (1440). valuator[1] is suspiciously large given the display height is 900. Perhaps this is a side-effect of having previously been using a dual monitor (although booting with that monitor connected does not help). There are other entries listed under xinput list: Virtual core XTEST pointer which seems stuck at position (840,1050). bcm5974 which seems stuck at position (837,6700). Removing the bcm5974 module using rmmod disables the toucpad as expected but does not fix the USB mouse problem. After adding the module back, it is stuck at position (840,1050) instead of (837,6700). /etc/X11/xorg.conf was generated by nvidia-settings and contains: Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "ZAxisMapping" "4 5" although I don't know how plausible these settings are. Any suggestions?

• How do I get the Apple Wireless Keyboard Working in 10.10?

  - by Jamie

  So I've gone and bought a Magic Mouse and Apple Wireless Non-Numeric Keyboard. The magic mouse worked out-of-the-box almost perfectly, except for the forward/back gesture which still isn't functioning, whereas the keyboard didn't. It has constant trouble with the bluetooth connection. Only the 7, 8 and 9 buttons and volume media keys correspond correctly with the output. Pressing every single key on keyboard has this output: 789/=456*123-0.+ When I use Blueman the keyboard can be setup and shows up in "Devices" but I get a warning when I click "Setup"; "Device added successfully, but failed to connect" (although removing the keyboard and setting it up as a new device doesn't incur this error). Using gnome-bluetooth I have encountered no error messages but it connects properly less often than Blueman and I can still only type the aforementioned output. What am I not doing? Where is this going wrong? EDIT: I have read this http://ubuntuforums.org/showthread.php?t=224673 inside out several times to no avail. It seems these commands don't work for me with the apple peripherals sudo hidd --search hcitool scan Fortunately I have the luxury of a 1TB hard drive, near limitless patience and no job. I have installed a fresh Ubuntu 10.10 64bit (albeit smaller than mine) and after updating and restarting for the first time, I set up my devices in exactly the same way as I have learnt on my original install I succeeded once again with the mouse and, to my joy, with the keyboard also. Though I could not seem to find Alt+F2 and had to reconfigure that and several other keyboard shortcuts, the keyboard is working and in a spectacular fashion. Still, this leaves me with the issue of my original install. I returned to it with some new found knowledge but failed again. Perhaps I have a missing dependancy? I did uninstall bluetooth after the initial set up and reinstalled it recently for the pupose of these peripherals. Maybe it's because I'm running 64bit? This is still not solved, but easily avoided by not changing too much from the original install. Just hide stuff or turn it off, don't uninstall too much.

• 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?

• very slow internet with Linksys WRT54GL only in wireless mode (wired is OK)

  - by gojira

  I bought a new Cisco Linksys WRT54GL router to connect my laptop (running Windows 7) to the internet. I installed Tomato 1.28 firmware on the router. When I connect the laptop to the router via ethernet cable, everything is fine and I get extremely fast up- and download speeds. When I connect wirelesssly however, websites load extremely slow - it takes dozens of seconds to load a website! <-- This is my question, how can I fix the wireless speed issue? Gmail for example is unusable this way. I tried speedtest.net, but this always fails in the upload part of the test so I can't even test the bandwidth (could the fact that it fails in the upload part, not the download part, be an indication what the problem is?!). I have isolated the problem a bit, I am convinced it has to do either with the router itself, the router settings, or the settings of the wireless connection in Win 7. Because previously, I was using another router by Buffalo and I had no problems whatsoever. I have tried to reproduce the settings from the Bufallo router as closely as possible on the Linksys router (same channel, same encryption etc). The download speed problem only occurs with the Linksys router, and only in wireless mode! When I exchange the Linksys router with the Buffalo router I have here for testing, the wireless speed is up to normal again. Also, before I had installed the Tomato firmware I had exactly the same problem, so it has nothing to do with the firmware itself. Notes & things I already tried: Changing the channel: does not seem to affect anything, I am also on the same channel (10) which I was previously on when I had a Buffalo router. QoS is off. Ping to the router itself is OK, ~ 1 ms. Some current settings of the linksys router: WAN / Internet Type: DHCP Wirelesss Mode: Access Point B/G Mode: Mixed Broadcast: check Channel: 10 - 2.457 GHz Security: WPA2 Personal Encryption: AES

• Configuring two nearby WLANs: should I use the same ssid?

  - by Rory

  I'm configuring a home network for basic internet use (ie don't really need connectivity between workstations on the network). My brick walls mean a single wireless router doesn't provide good coverage throughout the house, so I have purchased two powerline adapters and now have the incoming modem/wireless router at one end of the house plugged into a powerline adapter, and at the other end of the house the other powerline adapter plugged into another wireless router. Currently the two wireless networks have different ssids. (The powerline adapters only do power-Ethernet; they're not wireless access points themselves.) This works well, except when I move between rooms and would ideally like my devices (iPad, phones, laptops) to switch from the weak to the strong signal. Sometimes there's enough signal that they hold on to the weak connects instead of switching to the strong one. Should I name the two networks the same ssid, and if so what is the actual effect? Do the signals get confused, is the bandwidth affected, will this help my devices seamlessly move from one to the other, or is the ssid just a cosmetic thing that actually doesn't have any impact on this situation? Are there any other settings that I should configure to make my setup optimal?

• Middle Mouse Button does not work in XFCE / Arch Linux

  - by Alp

  I have the XFCE desktop manager installed on my Arch Linux system. With E17 (Enlightenment desktop manager) i had no problems with my mouse: all buttons worked correctly out of the box. But in XFCE my middle mouse button does not fire an event at all (no output with xev). Evdev seems to identify my mouse correctly (Razer Deathadder) because it echoes its name in the xorg logs. I have no idea what could cause this and how to debug the problem. I start both e17 and xfce with startx. Here is my ~/.xinitrc: exec startxfce4 --with-ck-launch #exec enlightenment-start

• Configuring home wireless network

  - by dvanaria

  I'm new to setting up a home wireless network. I have Comcast tv/internet/phone service (modem included) as well as a wireless router. My question is pretty basic. How can I tell the performance of the following parts of the network? 1. incoming internet speed 2. speed of the modem 3. speed of the wireless router I basically want as fast an internet connection as possible, of course, but I'm not sure where to look for the bottleneck (and so, not sure where I can spend some money to speed things up). Right now I'm getting about 36 Mbps (as it shows in Windows). If I run an online speed test (xfinity has one) it shows Average download speed of 14.91 Mbps and Average upload speed of 5.72 Mbps. Thanks for your help.

  I had Ubuntu 12.04 initially installed on my laptop. I upgraded to 12.10 then 13.04. Everything worked fine, including wireless. After adding a new memory card ( I only had 2 gb and one memory slot free) my wireess stopped working. I backed up all my data and reinstallled Ubuntu 13.04. Everything works fine except wireess. I bought this laptop in 2010 from Japan. It has Intel Core i5 CPU M 450 @2.40 Ghz * 4 3,7 Gb RAM os type 64 bit The output of iwconfig: eth0 no wireless extensions. lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off The output of rfkill list all: 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no The output of lshw -C network: *-network description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:05:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:7d:fe:fa width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.8.0-19-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:d6400000-d640ffff *-network description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:06:00.0 logical name: eth0 version: 02 serial: 88:ae:1d:2b:36:ac size: 100Mbit/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=full ip=192.168.2.2 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:41 ioport:2000(size=256) memory:d2410000-d2410fff memory:d2400000-d240ffff memory:d2420000-d243ffff The wi-fi network appears as disconnected ( it's greyed out) Strangely enough I see a wifi network ( not mine) but not mine or the rest.

• wireless network with cable modem and access point

  - by hayri

  I have a Scientific Atlanta EPC2203 cable modem and a TP-Link TL-WA500G access point. When I connect my computer directly to modem with a CAT5e cable I have internet connection on my laptop (when i type ipconfig i see my external ip there, provided by isp). So I decided to have wireless network in the flat, allowing other devices to connect as well. I bought this wireless ap (TL-WA500G) configured Wireless security stuff, and connected it to my modem. With that configuration (by default AP has static ip of 192.168.1.254) only my computer can connect to internet over wifi, but not any other device. When I set the IP of AP to Dynamic IP (DHCP) it is the same. How should I change my configuration to enable all wifi devices to connect to internet?

• windows 7 wireless knocks off other computers on the network

  - by Sean

  I am trying to fix a wireless network issue. When a new windows 7 machine (we have 2 in the house) we have problems with any other windows xp machines connecting to the wireless network. I am using a linksys WRT110 running Firmware Version: 1.0.04 (which is not the latest firmware its Ver.1.0.07 but the router would not use the bin update file). I have tried a ton of variations in setting for the wireless network, changed the channel, the security level (none, wep wpa, wpa2), network type (g,bg mixed). I have also read some stuff about homegroup settings for windows 7 but have not seen any differences that make a difference. Basically windows 7 does not like to connect to our network but when I manage to get it to work the windows xp pro machines get kicked off. The windows xp pro machines are a few years old but both windows 7 machines are less than 6 months old.

• set left handed mouse, then wacom stylus buttons switch too

  - by begtognen

  I'm using Lubuntu 12.04. I can set my mouse (basic usb mouse) to left hand (i.e. switch the left and right mouse buttons which is all I need) by going into Preferences / Keyboard and Mouse. However, it changes my Wacom stylus, so that when the tip touches the tablet it acts like the right mouse button, making it impossible to draw. Is there a way to have both happen at once? The stylus buttons working in right handed configuration, while the mouse works in left handed configuration? Thanks for any help/suggestions.

• Suggestions for wireless adapter

  - by Michael Kniskern

  I recently purchased a desktop computer and it did not come with a wireless network card. I am currently using the Belkin Wireless G USB Adapter and it is a very sub par product. It has very slow response times and download speeds with just basic browsing and downloads podcasts through iTunes. Does anyone have a better suggestion for a wireless adapter? Should I go with another USB adapter or one that connects directly into the motherboard? I am current using Windows Vista 64 bit Home Premium.

• Wireless internet sharing stops working after client disconnects

  - by Mandy

  I'm running Unbuntu 11.10 with the latest service packs, sharing an ether connection over wireless. Everything works fine, up to the point that the client (a laptop) sleeps or otherwise disconnects. The wireless connection at that point no longer functions, not showing up when searching for the hotspot with the laptop. The only way to recover is to reboot the machine, or toggle the wireless share off/on. I've double checked the wireless card has power management off. Currently what I'm doing is keeping an Ipod plugged into the box 24/7 to keep the wireless connection up when the laptop disconnects. I've searched the internet far and wide, found many issues with wireless problems after an ubuntu box itself sleeps, but nothing directly related to my problem. Hoping someone has some idea of where to look and what to check. A girl needs her Ipod back!

• Wireless does not work anymore after software update with Ubuntu 12.10 on a Dell Latitude E6230

  - by Andy

  I just installed Ubuntu 12.10 on my DELL Latitude E6230, on first boot wifi worked properly but when I updated the software it stopped working. I can't figure out the problem... The wireless network controller is a Broadcom Corporation BCM4313 802.11b/g/n Wireless Lan Controller (rev 01) "lshw -class network" gives, for the above controller: *-network UNCLAIMED description: Network controller product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:02:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f7d00000-f7d03fff After reading the answer to another similar question, I edited the file NetworkManager.conf to make "managed=true", but that did not make any difference, it is as if the wireless adapter were not there. In the "Network" setting window, I only see "Wired" and "Network proxy". Wireless has just disappeared: rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no and that's it! Nothing about the wireless controller... Any suggestions?

• bluetooth doesn't recognize mouse (and other devices)... sometimes

  - by Angelo

  I have a problem with bluetooth with Vista, running on my MacBook. It often doesn't recognize my wireless Magic Mouse. And I saw that it even doesn't seem to start as the pictogram in the task-bar isn't there most of the time I run Vista. But I'm only an Apple-nerd, so I don't know to much about this issue on Vista. When reinstalling Boothcamp or other updates, then once in a while bluetooth recognizes my own mouse (and other devices from some neighbours... so that implicates that the problem must be the bluetooth function in the first place, not my mouse.) Is there some update for the bluetooth application? Angelo

• Atheros AR5BWB222 Wireless Intermittent Connectivity

  - by Bart

  So I recently installed Ubuntu on my Acer Aspire V3-551 laptop. I have an Atheros AR5BWB222 wireless adapter. Everything works fine except for the wireless. I can sometimes connect to the wireless, but most of the time it will be making an attempt to connect and then enver connect. Or it will connect, but it will only stay connected for about 10 seconds before getting disconnected from the wireless. All the other drivers updated through System SettingsAdditional Drivers are fine, even the Ethernet. Its just the problem with the wireless. I've tried a power managment setting, tried looking for additional updates, but nothing fixes my problem. Is there any solution for my particular wireless card?
