I have a Wireless Linksys Router ( BEFW11S4 v.2). I have cable internet with speeds around 1700 d/l (test results from dslreports.com). When my router is connected, my d/l connections and speed drop to almost nothing in Kazaa Lite. If I just use the modem, my speeds and connections are great. I have tried port forwarding and everything else. Any suggestions. I have read that Linksys is not a good router to use for file sharing. I am thinking of purchasing a Netgear Wireless-G router.
