I do *not*, with = the same hardware and software configuration, have these problems if I use = the module "rt2500" from serialmonkey.com. In the ##kernel channel on irc.freenode.net, I have been told to write you an email about this. The problems are: a. Connection instability. Especially if the network quality is low, th= e connection is very unstable. I experience this as random disconnects (c= ould be after 10 mins, or 2 hours, completely random), and as having problem= s to establish a connection using DHCP (fails getting an IP adress). There i= s a correlation between my ESSID being displayed in "iwlist scan" network l= ist and the connection to be working, but the ESSID being found does not necessarily mean I will be able to connect. If the connection fails, it= is very very hard to re-establish it; loading and unloading the rt2500pci module several times sometimes solves the problem. It doesn't matter we= ather I use dhclient, dhcpcd, or NetworkManager (don't know which DHCP-implementation NetworkManager uses). b. Low bandwidth (limited to 1 MBit/s). This problem is probably fixed = with the newest release in the .29 kernel (at least, I didn't have problems = with that so far). I don't exactly know what information could be useful for you, so here = just some things of which I think they could be useful (please write if you = need more): lspci --snip-- 00:00.0 Host bridge: VIA Technologies, Inc.

--snip-- hwinfo (don't think this is usefull, but anyway... ^^) -> http://pastebin.com/f74793b41 If you need any further information, description of the problem, or hav= e additional tests I could run, I'd be glad if you would tell me. I again need to mention that the rt2500 module from serialmonkey.com wo= rks flawlessly with exactly the same OS and exaclty the same hardware configuration, so this is very unlikely to be a hardware problem. Unfortunately, it is discontinued (this is in fact the reason why I am writing this mail now :) Thanks and best regards, Sven
