Hi everyone, so im trying to help a friend of mine who is staying at a dorm. The dorm already has a modem when she first check in, but doesn't have a router so she went to get one. After hooking it up, she's connected to the WiFi but it returns with Request timed out. I looked at her set up and realised her modem doesnt have a land line connected to it, but has a optical cable connected. Im wondering if the missing land line is the reason why there is no internet access. Can someone assist here? Also shes there to stay temporary so it doesnt really make sense to get a land line nor the dorm comes with a land line. The staff there aint really friendly and did not help so im desperately looking for help anywhere else. Any help will be greatly appreciated! Thank you!
