I have just received my second replacement modem gateway f@st 5366 tn port 1 and 2 work fine 3 and 4 do not. My computer is connected to 1 my fetch is connected 2 port Xbox is connected to 3 port light flashes 2-3 seconds then stops same with port 4 anyone able to advise would be greatly appreciated?
Hi - the LAN ports on modems are provided internally in pairs, so maybe you are unlucky and have another hardware issue. With an Ethernet cable connected to LAN port 3 or LAN port 4, does your PC get allocated an IP address from the modem - it will be visible in your Adaptor Settings.
If you can open up a CMD screen in your PC or the Network Utility in a Mac - what do you see when you ping 192.168.0.1 which is the Gateway IP address of your modem. If you get a time out error or anything over a 4ms response and 0% packet loss, it may indicate there no IP address assigned to the PC from the Gateway, a hardware failure with the LAN port, a suspect cable, IP range mismatch in case your other router has a different range. Assuming you have restarted your PC between tests so that it gets a fresh IP address.
