I've been having this problem ever since I got my wireless router, it's a DG843G Wireless Firewall Router v2. I am not sure if it is my WG311T wireless adapter, or the router. The problem is that my connection goes from 54mbps to 2mbps very frequently, and when it goes to 2mbps their is almost no connection or little connection. I tried going to the NETGEAR Support system at their site, they told me to go to 192.168.0.1 and change my Channels but that doesn't work for me, I have not found anything that has worked. I already have the latest version for the router as well.
