    My ISP is Comcast and I am subscribed to a 12mbps download and a 2.5mbps upload. When I am directly connected to my modem I get around 13-30mbps (Yeah I know, I get more than what I pay for!)
    However, when downloading files through my router my max download speed is 750-770 kb/s.

    I am running Windows 7 Home Premium x64.

    I have tried this with a Linksys WRT320N and a Netgear RangeMAX (forget model) and SAME RESULTS!!!!

    I am very familiar with the menus of both.

    So, is there anything I can do to unlock the true potential of my speed through my router/s?

    *Added note: I have tested my router via ethernet and wireless. Same performance.

    I know 750 kb/s isn't bad. In fact it is perfectly liveable.

    Weird note: via speedtest.net the router and modem get the same speed. But, when I try downloading via P2P, Steam, random file sharing website; the modem outperforms every time.

    Thanks for the help! My first post on techguy.org!

    I'd download and install the latest firmware for the router, then reset it to factory defaults and reconfigure. See if that changes things.

    What's the exact make/model of the Comcast modem?

    I already have. On both routers they are at the current firmware with Windows 7 compatibility. The modem is by Scientific Atlanta but I cannot obtain the model number at the moment. (Not home for a few days)

    Did you also reset to factory defaults after the firmware upgrade? That's an important step.

    I have run across specific modem/router combinations that don't play well together. In my case, it was a Toshiba cable modem and a D-Link router. I stuck a cheap 100mbit switch between as a buffer and all was well. Even if just as a diagnostic measure, you might try that as well.

    Yes. Where can I get this switch you refer to? Do you suggest I get a wireless modem?

    Well, an Ethernet switch is a basic network component, you get them anywhere you might buy a router.

    If you have a friend with a different model router, you might consider asking him to test it in your location to see if this is simply a router/modem interface issue. You could also test your router in his location if he's reluctant to bring his to you.

    Wireless g networks only get up to 54 mb / sec speed

    if its wired straight to the modem youll get up tp 100 mb / sec

    depending how far away you are, the wireless should be fast enough

    atnerzig, you're not following the bouncing ball. His wired connections are slow, wireless doesn't enter this picture at this time.

    Since two routers have an issue, I'm starting to wonder if something odd is happening with the modem...

    I did talk to Comcast and they said all routers slow down my speed to that level. I just feel like that isn't the truth... Should I try a new modem?

    I believe it is a modem issue.

    That's a total crock! I've never seen any measurable slowdown with a router on any broadband connection, including Comcast. I had Comcast for years, and I had a variety of routers during that period, and I never saw anything like this.

    I have Verizon FiOS now, and the same comment applies. I've used at least four routers on this service, and it's always full speed.

    This could be an issue with the modem, that's all I can think of.
