I recently upgraded my ISP service speed to 18 MB down/3 MB up. When i perform a wired test to the modem, i get 19MB/2.7MB. But when i test thru my WNDR3700 wirelessly i get 10/1 (comp testing is on 2.4 gHz band). I have WEP for my 2.4 Ghz band and WPA2 AES for my 5 Ghz band. I've tried going to WPA2 AES on 2.4 band but had serious problems with connecting devices (WD Live Tv, Ipad, Iphones, etc..)
