I've been using the WRT54G for about 6 months now and recently it starts slowing down a lot for all the computer. I thought it was because of Downloading or something but if I turn the router off let it rest a little and turn it back on everything goes back to normal. However, today it happened again but when I turned it back on. No computer could connect to it. It said IP was rejected. I tried the "Ipconfig/release" and then "Ipconfig/renew" to refresh the IP. It works before however this time it says an error has occured and it couldn't get a new IP. So can I fix this or do I have to get a new router?
