I had similar problems using WPA, this time on on a belkin wireless router.
When I investigated I was told it was either the router iteself (it being
rubbish), or that I had too many other wireless things interfering with the
signal and causing it to crash, or my other equipment was too close to the
router and again, causing it to crash. I moved the router to another point
in the room. very highup and away from anything like my corless keyboard and
mouse and DECT phones. It seemed to improve the issue, but as soon as
somebody called me on my phone, the whole thing crashed again. Putting the
security back down to WEP helped, but I didn't want WEP because it is
releatively easy to crack. In the end I ditched the belkin and bought a
Netgear router - this one infact:

Since installing it, I've had no issues, and its been working on WPA fine.
