Query: stupid product!

I wish I read the previous review before I purchased this router.Yes, this was a plug and play router. Just plug the broadband/cable connection and viola! Instant internet connection. No disconnects, no problems.Why stupid? Whenever I turn WEP on, the router becomes useless. How stupid is that? WEP (security: either 64 ot 128 bit) is important but USR failed on this issue.PURCHASE AT YOUR OWN RISK!!!I trusted the US Robotics name because they made good modems. Now I know they are good only at modems. :(
