Query: Get Something Else!

Purchased what seemed like a good wireless router, but eventually the performance dropped, pages timed-out etc. I scoured the internet, but found that my particular model, the v4, has persistent problems, and neither the company nor anyone else had a fix for it. Eventually I replaced it with a Linksys WRT54GS. Not a problem since.
