Wifi frequent deconnections

Asked by jcglt

I suffer from frequent disconnections of Wifi on a laptop using Ubuntu 10.04 Lynx. I replaced network-manager by wicd, which improved largely the problem as, now, when disconnected the laptop will try and usually succeed in reconnectiong.
Here are the results of the procedure following https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

A quick fix that I'd say has a 50/50 chance of working is to upgrade to Ubuntu 10.10, this will include new drivers that could well be more reliable.

jcglt (jcjglt) said : 		#2

Thanks but I prefer to stay with a LTS version of Ubuntu and will upgrade only for the next one. By the way I started by an upgrade from Karmic and experienced many problems, I then decided to do a fresh install from a 10.04 CD and things improved tremendously.
Anyway my problem is not so acute : wifi was not working well with network-manager and I had to reboot in order to restart it. With wicd things are far better, I still suffer of disconnections but wicd will try by itself to reconnect and usually succeed, if not I just have to click on the wicd applet and it works after a few seconds, sometimes for hours, other time for a shorter period. I suspect also that interferences from other wifi boxes or even other transmitters (cellphones ?) might cause these breaks. This is just boring as my wifi works perfectly under Windows XP, which I don't use as I don't like Windows.

I've the same problem. I thinked it was a usb wi-fi driver but isn't. I've a wusb100 v2 wi-fi usb receiver and it works fine in windows. Ubuntu 10.10 use the Ralink driver rt2800usb. The connection is very unstable.

I've been running Kubuntu 10.4 since beta and didn't have any connection problems with my Intell Wifi 5100 wireless chip until a couple days ago, following the upgrade to a new kernel:
2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:52:42 UTC 2010 x86_64 GNU/Linux

After turning on my cable modem and wireless router I boot my notebook after the wireless is ready. I use wicd. I always get a connection. But, withing a minute or two the connection hangs. Even trying to ping the localhost (or 127.0.0.1) fails! Using wicd I can disconnect and reconnect but within a minute or two the connection fails again. Reconnecting and immediately using ping against google.com I find that the connection fails after the 46th ping, plus or minus a couple.

Strangely, wicd never drops my connection. It always shows me as connected. Ifconfig shows that wlan0 is still assigned to the 192.168.1.100 address. /etc/resolv.conf still contains my ISP DNS info. Iwconfig shows all the configuration details, as does "iwlist scanning". The routing table is unchanged. The only thing that tells me there is no longer a connection to the Internet is ping, and the fact that NO browser works.

Here is how I am presently circumventing the problem. I turn on the modem and wireless router and wait till they are stable. Then I boot my notebook and let it connect automatically, as it never fails to do. Soon after it fails I use wicd to "disconnect". Then I leave my notebook on and reboot the modem and wireless router. After they are stable again I refresh the scan in wicd and click on my access point. After I do this procedure my connection stays up.

I shall try to install the Windows XP driver with Ndiswrapper. I hope this will definitevely solve my problem.

Revision history for this message
jcglt (jcjglt) said : 		#8

I failed with Ndiswrapper and uninstalled it. I ten had to delete a "ndiswrapper" file in /etc/modprobe.d which prevented a permanent installation of ath5k module in the kernel and do a "sudo modprobe ath5k".
Now everything is working as before, not very well but at least it works.

jcglt (jcjglt) said : 		#9

I consider my problem solved. In fact nothing new and my wifi connection will regularly disconnect then automatically reconnect in a matter of seconds. I shall live with it, waiting for an update which will improve these matters and I shall stick to this 10.04LTS Lynx version, waiting the next LTS version to change as it seems that 10.10 users are facing similar problems.
It's only a pity that we cannot have a wifi as efficient as Windows' wifi.
