I still do not think it is a driver problem. The main change between the 3.xx.yy.x and 4.xx.yy.z
drivers is the firmware.

Your loss of connection could be some interference on channel 11. You need to try channels 1 and 6
to see if they also have the same problem. If not, it was interference. If they do, it could still
be interference, but it might be your hardware.

Do you have a portable phone with a 2.4 GHz carrier? How about any Bluetooth devices? Does the
hangup correspond with the use of your microwave?
