WRTG2 problems when hooked up port1 is very slow port 2 is fine.But when i connect upcomputer on port1 dorectly to modem it runs fine.What could be the problem,Router is brand new Davidw

Generally one port is shared with the uplink port. Uplink is a port you can use to add a switch/hub to increase the number of users. There may be a switch to toggle between normal & uplink. Did you read your instructions? That should be explained in there. To further explain, Your router is actually a router/switch. As a switch the packets should be managed. An auto-switch "directs traffic". If you have 4 ports on the router, for instance, the auto-sensing circuitry will allot time to each port. Depending on how sophisticated the hardware you might be able to shutoff or throttle one or more of the ports. That would allow more speed to the remaining ports. Uplink port might not be throttled at all. Many variables in play. Some hardware may not have any of the described features. Professional switches are much more expensive because they do have those types of features. I am by no means a networking expert so if other members here find major errors in my answer please feel free to correct.

trying to figure out if i can shut off ports 3 and 4 but it doesnt say in the directions Davidw

Is there a switch for port #1? If so, set it for regular as opposed to uplink. Or don't use #1 at all. Did any software come with the router? Is the router a wireless model too? Sometimes simply re initiating the router will straighten out a problem. There may be a hole or button to re initiate. If not, unplug for about a minute.

still messing with it havent had any luck ran cd that came with it it did some firmware updates but stil no luck Davidw

Are you measuring speed or just ball parking?
