I have a 501 PIX hooked up to my cable modem. I have a 3 MB cable internet connection. In the last week or so things have really seemed to slow down. If I hook a laptop up directly to the cable modem I usually get a 2 - 2.5 MB when doing a speed test on http://www.speedtest.net/ When I hook my PIX up to my modem and hooked up my laptop to the pix, my speed is cut in 1/2 or more. Any ideas of what to check? Thanks!
