Haphazard wireless internet

[Paul Orton]

Incredibly slow this morning, timing out at most sites. Other symptoms on other days - constantly asking for my wireless key, losing connection completely from time to time.

****N.B. This thread relates to a different machine to that in my other recent thread****
Running 10.10 2.6.35-22-generic

dmesg | grep firmware - this returned nothing.
Other files attached.

Remaining files - as you can see I had to split dmesg.txt because it was too large.

This problem affects 2 machines here, both wirelessly connected to a 3rd machine which has the wired connection to the internet. Both of these machines have dual boot setups : the main machine with Vista/Ubuntu 10.10 and the spare with Windows 7/Ubuntu 10.10. On both machines the wireless works fine on Windows but not on Linux.

Typically the wireless connection succeeds immediately on both machines (when running Linux) but it fails after 10 minutes or so and cannot then be recovered. When it does work the connection can, but not always, be incredibly slow at downloading pages.

NB. The technical data shown in the first 2 posts of this thread refer to my spare machine (the Windows 7/Ubuntu 10.10 one).

I saw this.

[ 11.215905] rt2870sta: module is from the staging directory, the quality is unknown, you have been warned.

But you're also using several different modules, which I think could be interfering with each other. You might try blacklisting the rt2500 and see if that helps.

Thanks, Mike, but I haven't got a clue about any of this. I don't know what these modules are or how to blacklist them. Is there anywhere I can read up about this?

[MikeTbob]

Add them to /etc/modprobe.d/blacklist

kdesu kwrite /etc/modprobe.d/blacklist

Add the modules by name.

blacklist rt2500pci
blacklist rt2x00pci
##added by Paul Orton, for testing.

Save and Reboot, if this makes things better, your good to go. If it does nothing, well we tried.
