Motorola Droid X :: WiFi Slow Down Stream?

the wifi on my X has become increasingly slow but only on the down stream connection. speed is about 500kbs where upstream is 5.5mbs. vie tested other devises on wifi and they all get in the 12-20mbs range, and prior to noticing this i had tested my x with 8-12mbs down. nothing has changed on the router since this has occurred. after struggling to try and fix it, i reset my droid to factory and it still its a wall at 500kbs. i used speed test for both the old numbers and new numbers. both the app and the website agree on speeds the device is getting over a wifi connection. after this i also tried changing the settings to an open network that did not advertise its ssid, this did not change the results. the tests that had the 8-12 range were done from july last year to december, i switched routers in october so i was testing frequently for awhile. both routers had roughly the same speed for the droid but were faster for 5ghz range N devices.I first noticed the slower speed in late january and started testing then router is a netgear wndr3700?
