Sounds like a physical issue- how old is the router? My guess is that the wireless antenna is going bad, if it was a software issue it would have been corrected by the updates or would have the same issues with wired connections.
If you can contact the vendor you purchased this from, it may be under warranty and you could get it repaired.
