    Ok, First off I have road runner with a SB4200 modem Its a 5mbit connection.

    I have a WRT54GS v2.1

    Ok I get a good wireless signal and fast speeds over the lan about 25mbits+ now when i try downloading over the internet its a different story all the wireless clients are limited to 2mbits a second and as soon as i hook up a cable I get the full 5mbits again.. I have having trouble finding the bottle neck here I have tryed every wireless setting there is to speak of and it has no effect nor does disabling wireless security. I had the same problem with my WRT54G v1.1

    Could this problem be the SB4200 modem(2 years old) it self? what could cause this kinda bottle neck is there any troubleshoot tips anyone has for me?

    Wireless with a strong encryption could reduce your speed up to 40-50%, but you should get at least 90% of your ISP's connection speed with encryption and/or NAT disabled, (for testing purposes only). I'd doubt it's the modem since you get good speeds over the LAN. Try a firmware that will allow you to boost your signal strength, such as HyperWRT and adding your client's MAC's to QOS on high setting. Also, I've heard that Speedbooster works well when the clients are at close range to the router, but at a good distance causes problems. So, if your clients aren't near the router you may want to try disabling Speedbooster. Well, that's a start. If these suggestions don't work you'll have to wait for an expert to help you further. Good Luck! :cool:
