WIFI problems, would love help with solutions

Post by vanya »

Dear helpful community,
Recently installed 32-bit linux mint 11 (Katya), on a Sony Vaio VGN-N21E laptop.

I am unfamiliar with Linux, but so far I really like it. Only thing is I am having problems with my wireless, I've already done a (reasonably intensive) sweep of the forum/google and yet haven't found any successful solutions. However I hope with your help it shouldn't be a major problem.

So I can connect to wired alright, and every so often the wifi connects, but the connection is sporadic and requires to be close to the hot spot (in the rare times when it does work). Often I need to reboot and it will connect again, but only for about half an hour before cutting out. I've been led to believe this is a problem with the wireless driver (but possibly I'm wrong).

So here are some details:

Code: Select all

vanya@vanya-VGN-N21E-W ~ $ inxi -N lspci lsusb

If there are any other details you would like, I'm happy to provide. Would love to get this sorted out so I can get started learning more about linux!

Thanks,

Just wondering if you've seen this thread?

http://ubuntuforums.org/showthread.php?t=1484924

Mint is based on ubuntu, so if its a bug there, its probably a bug here too...

Thanks for the link, however I tried rfkill list and got:

Code: Select all

vanya@vanya-VGN-N21E-W ~ $ rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
So I don't think its that. Apparently problems with the aetheros 5001 driver, are common: http://forums.linuxmint.com/viewtopic.php?f=49&t=49736
The problem mentioned in that is similar to mine, but in my case, as I'm running LM 11, I don't think updating the kernel would work (?)

Any ideas? Thanks again.

well actually... you never know - it might.

The last time I updated my kernel I got support for my sandy-bridge wireless. so it might be worth a try.

search the web for a guide on a how-to.. assuming you don't have the latest version that is
