I am supporting a small office that has a cable modem, WRT54G v5 with latest firmware, Dell 16 port switch, and 8 Windows 2000 SP4 clients. The router intermittently drops the wired connections anywhere from 5 minutes to several hours, but the wireless connections are preserved to two laptops. When I ping the router's IP address, 192.168.1.1, from any of the PC's, I get timeouts. Power cycling the router brings the wired connections back. I have tried another router but no change. this is really driving me crazy. Any ideas are greatly appreciated.
