I've been searched a solution for enabling wifi functionality under my Kalyway 10.5.3 for about a month (since installing), and the only way I see is purchasing new adapter. Unfortunately there are no places in StPetersburg to buy such card (I've found only atheros and i3945, which are also known malfunctioning), so i searched any other, and found possible solution on eBay

I'm planning to get it in a few days and 'll write about success or not.
