I have been playing with the Feb '12 debian armhf image and I have issues with the wifi. The device connects first time about a third of the time, after turning the h/w radio switch on and off a third of the time and the rest of the time will not connect at all. When it does connect, it can lose the connection after two minutes or it can stay connected perfectly for two hours.
Has anybody else experienced this issue? The wifi is perfect in the latest maverick image, my router is a Linksys WRT54GS.
