System monitor's connection graph looks more solid in Karmic than in Jaunty, with smaller gaps. But I am feeling lower transfer rates on local network. Its only a feeling, I did not measure it before updating, sorry. Now, for large files, on the same room, I get an average of 2MB/s receiving and 1MB/s sending. Is it ok?
Some data:
1) indoors, same room, 2 meters away

Bit rate setting is auto, but it does not go 54Mb/s. If I force it I have connection issues. My signal level deviates between -22 and -17 dBm. No packet loss:

So things are better in Karmic, but not 100% for me, yet.
