Public bug reported:
Using a WMP54G v4.0 ralink 2500-based card, Feisty freshinstall detected
the card out of the box. However, after a few minutes (sometimes hours)
of continuous use, wireless performance degrades to a crawl. Pings from
the computer to the router take from 600 msec to 4000 msec, (when all is
well, they take between 1 and 2 msec).
Also, network-manager didn't detect the available SSIDs and won't allow
me to connect to any wireless network. I had to put the interface in
Manual mode and enter the SSID manually.
I tried complete removal of network-manager (which didn't work,
anyways), same performance problem.
Finally I blacklisted the rt2500 module and installed ndiswrapper, like
I did long time ago for breezy, dapper and edgy. It's a bit sad.
thanks.
