It's my first bug report

There is very little we can do here, please report it upstream. Also what driver do you use for your chipset etc, is it provided by the kernel?
Comment by Vesa Kaihlavirta (vegai) - Sunday, 24 July 2011, 13:46 GMT
I can confirm this. I have the same wlan chipset and noticed a slowdown at some point. Cannot pinpoint the exact kernel version, though :-/
Comment by Jelle van der Waa (jelly) - Monday, 25 July 2011, 07:35 GMT
Again please report it at the kernels bugzilla / developers of the chipset

isnt powersaving set?

Note that this might be related to specific router chipsets also. My problems faded away when I exchanged my Buffalo WBMR wlanrouter+adsl modem to a Linksys WAG320N.

Also, I was able to witness the same problem on two different computers with the same WLAN chipset. One was an older Toshiba Equium A200 and the other a new Thinkpad Edge 0328-24G

Powersaving isn't set (desktop computer).
My router is the common linksys wrt54g - I don't see any problem when connecting from windows system (both download and upload speeds are correct) so don't think it's router related.
Thanks for replies.
