Upload speeds extremely slow using Netgear FVS336G Dual WAN router on Comcast

    Download speeds, per speedtest.net and speakeasy, are about 20mbps.

    When the speed test gets to the upload part, it usually hangs or takes a long time before giving me a result of about 0.04mbps. Basically, it's so slow, it sometimes just gives up and times out.

    This translates into a real shoddy internet experience because something as simple as choosing airline tickets requires your computer to "upload" your choices. And of course, if that doesn't happen within a certain amount of time... Timeout! :mad:

    I have tested the connection without my Netgear FVS336G Dual WAN router in the way and it is much better so I'm certain it's the router.

    When I tell the router to use WAN 2, which is where my AT&T DSL connection is on, the upload works just fine (about .4 mbps - I'm provisioned at 512kbps so it's fine).

    Also, this is the case on ALL computers on the network - wired, wireless, PC, Mac, iPhone, iPad, you name it. So, it's definitely not device specific.

    This is for a client I do work for all the time, expects great service, and pays me well to have it so.

    Any help would be great!

    It sounds like you narrowed it down to either the router and Comcast are not working well together or else a problem with one of the router's WAN ports. Can you switch which ports are connected to Comcast and AT&T to farther isolate it?
