Ubuntu Networking :: Broadcom Wireless Stopped Working

Jan 18, 2011

I have a HP Mini 5105 SSD netbook, runing Ubuntu 10.10 with 2Gb RAM. My wireless card is a Broadcom BCM43224 802.11a/b/g/n. Its driver is enabled and running. The wired network connection runs fine too. The problem: Wireless stopped working. When I right click on the network icon, the enable network option is clicked, but the "enable wireless" option is listed in dark grey and cannot be clicked on. I have recently updated my kernel version to 2.6.35-24-generic. What I have already tried: this one too I got to know there seems to be a problem with the 2.6.35-24-generic kernel. I have gone into the GRUB menu (it took some time to find out that you have to keep the Shift key pressed during startup for the GRUB menu to show), chosen the older kernel version (2.6.35-23-generic) and then removed the faulty one. Nevertheless, nothing has changed. I still cannot enable the wireless. The outcome to lshw -C network is:

Ubuntu Networking :: Broadcom Wireless Stopped Working In Lucid?

May 5, 2010

after having tried out almost all suggestions found here and elsewhere on the internet, i'm somewhat at my wits end The situation: I'm running Kubuntu 32Bit Version (at the mom 10.4) on a HP-Compaq 6735s (AMD Processor, Vanilla 32Bit Install). My first Install was last year with 9.4 and the Broadcom 4322 wireless worked like a charm after installing the proprietary STA-driver under System -> Hardware Drivers. As the update didn't work out really without glitches, i did a fresh install and lost my wireless. I tried various combinations and tutorials but to no avail. My card is found, the driver installed, but i cannot access my access-point. I can SEE the access point (and all my neighbors'), but knetworkmanager does not seem to do anything. To be sure, I installed wicd (nice tool by the way). Trying a connect here told my my credentials were bad (incorrect passphrase for my WPA2 Personal auth), which is not true. I tried connecting without security, didn't get an IP. So it seems somehow the card is working, but all functions needed for passing information to the access-point are unavailable.

This is what I tried:

both broadcom-drivers
fw-cutter
installing the driver by hand

Installing the driver via Hardware Drivers produced the same results as any other, viz the card is working, but not connecting. Unfortunately knetworkmanagers error messages are a bit sparse, or rather non existant. My guess is that somehow the firmware is not properly loaded (or the wrong type??).

Fedora Networking :: Broadcom WLAN Suddenly Stopped Working?

Feb 9, 2009

I have an HP Pavilion notebook with a Broadcom WLANcard that had been working very nicely in Fedora Core 10 until this evening, when I took my notebook to a conference room where there was no internet access. (I tried to connect to wireless networks, but there were none in the area, as I discovered.) am now unable to connect to my local (home) wireless network as the device is now non-existent . Can someone please walk me through the steps to fix this or re-install it (I have tried reinstalling broadcom-wl, but that didn't help). My lspci listing is reproduced below:

Ubuntu Networking :: Wireless Suddenly Stopped Working AND Rfkill Command Not Working

Jul 13, 2011

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.

Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.

I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

Ubuntu Networking :: Broadcom Wireless Card Not Working After Upgrade

Jan 1, 2010

Ever since I upgraded to the new Ubuntu, I have been having problem with wireless. In the "Hardware Drivers" I come up with 2 drivers:

1) Boadcom B43 wireless driver
2) Broadcon STA wireless driver

I activated the first one, but latter noticed that the wireless was not working, so I tried installing the second and it returned this message:

Ubuntu Networking :: Wireless Has Stopped Working?

Feb 25, 2010

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.

I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?

The USB adaptor I'm using is a Trendnet TEW-424UB

Ubuntu Networking :: Wireless Stopped Working On 10.04?

Aug 4, 2010

Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.

However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

Ubuntu Networking :: Wireless Suddenly Stopped Working?

Jul 24, 2010

I'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.

Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.

It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.

Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.

I'm using a different computer to post this thread, so I'm manually writing the output.

Code:
sudo iwconfig wlan0
wlan 0 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off

sudo iwlist wlan0 scan

Ubuntu Networking :: Wireless Connection Stopped Working?

Oct 20, 2010

About a week ago I upgraded to Maverick from Lucid.

All networking worked fine on Lucid.

I am using an Acer Laptop with the Atheros AR928X Wireless Network Adapter.

I can connect to my home network (visible, with WPA2-Personal) fine. However, I cannot connect to my university's wireless network. The only difference I noticed is that its network is using WPA2 Entreprise with Tunneled TLS Authentication and MSCHAPv2.

I tried dmesg and I got:

wlan0: authenticate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: authenticated
wlan0: associate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: RX AssocResp frin 00:1a:1e:ef:f4:e1 (capab=0x431 status=0 aid=2)

[Code].....

Unless the driver has changed, I suspect this is not a driver issue, since it worked fine on Lucid. Is this a NetworkManager issue?

Ubuntu Networking :: 10.04 - Wireless Suddenly Stopped Working

Apr 18, 2011

I'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.

Ubuntu Networking :: Wireless Just Stopped Working For No Reason?

Jul 13, 2011

I go to the icon and it says "wireless is disabled by hardware switch", well I didn't press any hardware switch. My laptop is a Dell L501X, the "hardware switch" is the Fn button and F2. I've tried pressing this but nothing happens.

Is this a bug with the latest linux version? Cos everything was working fine until my laptop updated.

The version I have now is "Linux 2.6.38-10-generic"

I'm running 11.04 64bit.

Here is some info from console :

Ubuntu Networking :: Wireless Has Stopped Working Karmic Koala

Jan 20, 2010

Today my wireless has stopped working. I have a laptop hp6720s with network controller: Intel corporation PRO/Wireless 3945 ABG [Golan] Network connection (rev 02), dual boot vista/ubuntu 9.10, fully updated (kernel 2.6.31-17). I use a router edimax BR-6204 wg to use the net with other laptop. Till now i have using wicd for controll wireless without any problem, internet was quick and responsive. (Quick connection without any failure).

But today the internet was very slow and wireless starts to connect and disconnects intermitently, doing it unusable. This was what occured when i upgraded from jaunty to karmic and used the network manager from gnome, but then i fix the problem installing wicd. Now wicd behaves in the same way as gnome-network-manager. If i connect directly the computer to the router by wire, i have internet and everything works perfectly. How i can fix the wireless?. How i can do it works with ubuntu 9.10 and?.

Ubuntu Networking :: 10.4 Wireless Has Stopped Working Since A Recent Upgrade

Jul 9, 2010

Like many others it seems, my wireless has stopped working since a recent upgrade The answer does not lie in analysis of logs, settings etc. but surely with those who did it - they should provide a fix. I cannot believe everyone expects each individual users to go into their own analysis of why this is no longer working as it is clearly widespread. I have been using Ubuntu for 18 months without this problem on the same dual-boot laptop, and it still works on Windows as before, only Ubuntu 10.4 has recently stopped my network card from working.

I need to know when this will be fixed. I have been embarrassed by promoting Ubuntu to many colleagues who now also cannot work at home on their wireless networks. Seriously disillusioned I may start looking for a more stable alternative to Windows.

Ubuntu Networking :: WPA Wireless Stopped Working After Recent Update?

Additionally, I just installed 10.04 on a Gateway laptop that's a few years old. It immediately connected to the WPA network and I ran the updater. Lo and behold, after updating it no longer connects to the network.

Ubuntu Networking :: Wired Network Stopped Working / Wireless OK

Sep 21, 2010

I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!

I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...

Ubuntu Networking :: Wireless Stopped Working [Maverick] / Where To Start?

Nov 15, 2010

I'm using Maverick and since yesterday, my wireless hasn't been working. It was working before with Maverick and I don't recall doing any updates that might have changed wireless configurations.

By "doesn't work" I mean it doesn't recognizes any networks, as if the wireless was turned off (there's this button on laptops, but it's turned on). I had that problem some time ago, but rebooting solved the problem, which, now, didn't.

My laptop is a HP dv6420la.

Where to start?
