Cant reconnect after initial wifi connection

maddog39 · 2010-09-03 18:56:50

Hey everyone,

I have been having this issue across Linux distros, mainly Kubuntu and Arch. I am running a Lenovo IdeaPad S10 and I am having wifi connection issues. The initial wifi connection I make when I boot up the machine works fine. However, the wifi connection will often drop at which point I will no longer be able to connect to any wifi access points at all. It simply gets stuck reconnecting until it times out, or if its a protected network it will simply keep prompting me for the password. Any thoughts?

Thanks in advance for the help.

Could you post your wifi chipset and the driver/firmware versions you are using? What are you using to connect to networks, netcfg, wicd ...? Are you current on pacman updates?

So are you able to browse the internet or anything else after the initial connection, or does it just connect and then it immediately stops working? Try disabling the automatic connection during bootup and open a command prompt after you've logged in and run whatever connection utility you use. You'll likely get 'some' kind of output that might be useful.

I can browse the internet for the initial connection just not after the connection drops and I cant connect to any access points anymore.

05:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

I am using the latest b43 driver/firmware available. I also running current pacman updates and I have disabled the automatic connect with the same results. The network manager I am using is primarily networkmanager but I have also tried wicd with the same results.

Alright it just dropped connection again and I found this in my errors.log:

Okay well I have upgraded kernel26 to 2.6.35.4... everything seems to be going well so far, lets hope it stays that way. Thanks a ton for the help!

No problem, glad it's working! Networking issues are really annoying.

After you've determined it's working go ahead and add [Solved] in the front of your subject line.

Thanks,
