I just purchased a Belkin F5D7230-4 yesterday. Got home and hooked it up no problem. Configured my PS3 to it no problem. Web surfing was fast and easy. Its hooked up to my Bright House DSL. I went on the Play Station network to download a demo game. It took 6 hours to download a 1500kb demo. Signal power was between 90%-100% the whole time. Is this the download time i should expect with only a G-router or is the download time so long becausde of my internet speed. My internet speed is 7 mbps. Will upgrading to the 15 mbps speed up my downloads or is this the speed i should expect with a G-router.
