Problems with rt2800

[davm92]

Hi, i have a touchsmart 300 wich worked fine with the last version (lucig lynx) of ubuntu, (in fact i had to make a change in the /etc/Wireless directory to make my wirless work)

sudo mkdir /etc/Wireless
sudo mkdir /etc/Wireless/RT2860STA
sudo gedit /etc/Wireless/RT2860STA/RT2860STA.dat
Default

Now that i've upgraded the wireless card doesnt work any more, after some research in the forum I made the conclussion that the change in /etc/Wireless is affecting the dirvers that came with the new version (maverik). but before blacklisting( I dont know how to do that) whats your opinion, here there are some codes, feel fre to ask me for more.

sudo iwconfig

Can you determine if it is scanning for or can see the available networks ?
Try this in terminal

iwlist scanning

Your card will work with either rt2860sta or rt2800pci and its dependents but probably not both. Let's blacklist the rt2800pci family and see if we get it working. In a terminal, please do:

sudo gedit /etc/modprobe.d/blacklist.conf

Add four new lines:

blacklist rt2800usb
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00lib

Proofread carefully, save and close gedit.

Reboot and post back and tell us how it's working.

Will this do anything if he doesn't also blacklist rt2800pci and rt2x00pci? I have similar issues on an eeepc 901. Perhaps the difference is that it works fine on my home WEP network (except when waking up from hibernate). It hasn't worked at my work WPA network since I installed from the live CD.

When I blacklist the pci items along with your 4, it won't connect on the WEP network. When I only blacklist your 4, it appears as if they load anyway. (children of the pci modules?)

UPDATE: I blacklisted rt2860sta on my machine. The WEP networking still worked. It came back after a hibernate cycle. Will try it on a WPA network tomorrow...

You are correct; my bad. Those need to be blacklisted, too.

[davm92]

thanks chili555 and not_a_phd, you and me were right, thanks to the other users which contributed to the answer, my wireless is now working.

I am glad for you...Mine is sort of working at this point... It looks like I need to blacklist rt2860sta when I am at home, and blacklist the rt2800 and rt2x00 family when I am at work.

I think the best way to handle this perhaps is with a script. I know how to remove these modules using the rmmod command. Do I insert the correct ones with insmod? if so, where do I locate the .ko files?

insmod, which requires the absolute path to the module, is not the handiest way to do this. I suggest:

sudo modprobe rt2860sta

It's hard to accept that one module works at home but not at work and vice versa; but I guess anything is possible.

To find the location of any module, do:

modinfo yourmodule

For example:

modinfo rt2860sta
filename:       /lib/modules/2.6.35-22-generic/kernel/drivers/staging/rt2860/rt2860sta.ko
version:        2.1.0.0
alias:          rt3090sta
license:        GPL
description:    RT2860/RT3090 Wireless Lan Linux Driver
etc., etc.

I hear you. At this point it seems that neither driver-set provides a completely stable solution. I just tried to sleep the machine, and when it came back up, the wireless would not reconnect.

I think I have seen some other threads in this category that address that issue, so I am off to find them!
