For some reasons, my WRT54G v2.0 is very slow now. I'm not even talking about the wireless signals. I'm only using the 4 wired ports of the rounter. It's even slower than dial up. I've tried my older wired router and the connection is very good. I have the latest official firmware. Do I have any chance of fixing it? an how? I've had it for only a year. Any suggestions is appreciated.
