Query: Stops working twice in a week

I saw so many reviews that the Linux version is very robust. But was not so impressed with its performance. At least twice a week it stops working. The wireless network would be missing. I have not done any advanced configuration. Need to power cycle the router to get network back. Verified by directly connecting my notebook to the modem and the line is up, so network issue is ruled out.Maybe some one can suggest me any patch to be applied.
