k42j Wireless problem.

i use asus k42j and ubuntu 11.04 but i can't connect wireless although see network? now what must i do? help me!!!!

Hello and welcome to the forums,

Which k42j model is it? There are several models http://www.asus.com/Search/?SearchKey=k42j

Can you open a terminal, then copy and paste the following command, then post the terminal's response here? ``` lspci

PS. I moved your post its own thread.

Regards,
uRock

Not a fix but.....

I have had similar issues with ASUS N73J with Windows 7 dual boot.

Mine does connect to the wireless most of the time, but will sometimes continuously search just after startup - this seems to happen more often when windows has been hibernated or if it was the last OS used.

Rebooting seems to get rid of the problem, but I would appreciate a fix too if anyone has one.

Booting ubuntu twice is still faster than starting up windows once, so no huge problem!

Hope this helps: (from N73J)

Are you using 11.04 or an older version?

11.04

If you are using 11.04, then installing the linux-backports-modules-net-natty-generic package should do the trick with your chip set. I am getting this info from this bug report, where one of the last comments claims it fixed the problem. You can install via the Ubuntu Software Center or via the terminal with the following command; ``` sudo apt-get install linux-backports-modules-net-natty-generic

As for 10.04 and 10.10 here is the Ubuntu documentation page explaining what to install. [https://help.ubuntu.com/community/WifiDocs/Device/Atheros/AR9285](https://help.ubuntu.com/community/WifiDocs/Device/Atheros/AR9285)

Thanks a heap uRock,

It's installing now, I'll put up another reply in a week on whether the issue is gone.

That'll be great. It'll make life easier when someone searches for the same issue and can read that the fix works for others.:)

Just a quick update: The above fix worked fine on my N73J.
