Hello People, I have a problem today with my WRT54GS 1.1 (with dd-wrt 23 Sp1). All my LAN clients (via ethernet) cannot acquire IP from router. All the Wlan (via Wireless) can acquire IP easily from router. I have tried everything: 1. Resetting router to the default setting. 2. Power OFF router. 2. re-download the firmware and reflash the router. 3. turning off DHCP and let the clients assign themselves IP. the client sure can get itself IP address. However, itcannot even ping to 192.168.1.1 (where the router address is). Can anyone tell me what has happened?
