WiFi works only temporarily on Asus EEE

[BrandonSk]

Dear all / Chili,

I went through the procedure as described in this thread:
http://ubuntuforums.org/showthread.php?p=12440411

As Chili suggested, I am starting a new thread so that may hopefully be useful for other people as well.

Here is of lspci -nn | grep 0280 :

lspci -nn | grep 0280
01:00.0 Network controller [0280]: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe [1814:0781]

Thanks for help.
Brandon.

Try disabling power management for your wireless card:

I assume you are using the driver rt2800pci and haven't compiled or otherwise installed anything different; confirm:

lsmod | grep rt2

If so, please try:

sudo modprobe -r rt2800pci
sudo modprobe rt2800pci nohwcrypt=Y

If it helps, we can make it persistent.

I'm running Xubuntu 12.10 on my eee pc 900 with no problems, the wifi seems to work perfectly.
I did update the BIOS which improved the battery life, the fan is running a lot less.
I posted how to here:

@Chili
I am using the driver you suggested. In fact, as mentioned before, I have followed the previous guide, so I have downloaded the same stuff. The version of the driver is 2.4.0 I believe.

lsmod | grep rt2
rt2860sta             769209  0 
rt2800pci              18340  0

eeprom_93cx6           12687  1 rt2800pci

sudo modprobe -r rt2800pci
sudo modprobe rt2800pci nohwcrypt=Y
The above returns nothing.
Oh... I see, it first disconnected me and now has reconnected. I will unplug the cable and get back to you within few minutes. It does "go off" within 30 minutes.

@Coldraven
Thanks for the link. I will check that tutorial. If nothing else, battery life and fan sounds promising too.

@Pjotr123
Thank you for the suggestion. I think my powermanagement for wifi card is off. At least I remember seing it as output of one of the commands before (I mean the previous thread that I have followed).

Thanks again to all.
Cheers,
Brandon.

PS: Unplugging cable now. Fingers crossed.

Well,

I am sorry to disappoint, but this time it worked only for a minute or so. When I removed and reinserted the module with those two commands above, it again started working but again only for a very short time.
On the third attempt it was not working immediately after the 2 commands were executed.

So I did try the procedure from scratch.

This time not just copy/paste but also looking at the steps and thinking, what is the aim and thus adjusting few commands. Particularly I was messing with the step #6 - the "mv" and revised "cp" commands.
With the mv I have renamed the rt2860sta.ko into rt2860sta.ko.dist which resided in my .../net/wireless
Looking at the revised cp and my directory structure, I first created a directory called "rt2860" in my .../staging/ and then copied the rt2860sta.ko into that newly created directory.

The "..." is /lib/modules/3.2.0-35-generic/kernel/drivers/ and yes, the 3.2.0-35-generic is what uname -r returns.

Result: still the same situation - wifi not working, although connected.

For better orientation, I will now post output of several commands, maybe you can spot something.

What is this Invalid misc:10 ? Does it lead to anything?

I understand the last 2 errors, as I have renamed the module to have ".dist" at the end.
What I do not understand is, how come the wifi gets connected, even when the module cannot be loaded?!

Well, any help is still greatly appreciated.

Cheers,
Brandon.

If it's connected using rt2800pci, why, oh why did you go to the effort to compile the genetically inferior rt2860sta? I must be confused...

Ooops. Most likely because I have very limited knowledge of linux and its drivers
The reason was that it suddenly stopped working out of nothing (it used work before but it must have been some update). So I started searching for solution.

Is there a simple way to get rid of all the drivers and let the system install whatever it prefers? If not, I am quite ready to do reinstall.

Thanks.B.

Sure.

cd Desktop/RT2860folder  <--or wherever you extracted the files
sudo make uninstall
sudo modprobe -r rt2860sta

Reboot and let us have your report. If there is anything not working, we'll address it, but older, inferior drivers won't help.
