I tried the 3.10-rc6 on ubuntu 13.04 amd64. No improvement. I assume the patch did not make it into rc6. I tried the script for updated kernel 3.10-rc5 that Xcalin posted. I have yet not tested it to depth but so far it seems to be working great. Better connection. So far no disconnections. I am very satisfied. Thanks a lot! Bjørn 2013/6/16 Christoph Vogler
