Doesn't sound like your isp is limiting your bandwidth....what modem are you using??

I have AT&T DSL, with a Speedstream 5100 modem. I also use the dlink 624 router, but both router and modem use 192.168.0.1, since this is a conflict, I had to put the router in bridged mode.

See article here: http://www.dslreports.com/faq/11827

This may or may not help you...but I'm sure at this point your willing to try almost anything.
