I'm running latest updates of SLES on my RasPi. However, Wifi throughput seems to be quite slow. When running an update with zypper the DL speed is somewhere between 50-150KB/sec (I have a 120MBit internet connection). Also, when copying a file from another computer via scp to the Pi, the speed is around 200KB/sec and after transferring 5-10MB the connection is terminated and the copy aborts.

Is this a known issue?
