Walked in on a hotel wifi network that has 1 modem and 8 routers/ap. What is going on (I didn't set this network up orginially) is the internet is getting to the modem and then to the router fine. But, when the Lan ports are pluged in the network is still avalible the the interet is dropped. unplug the Lan lines, which are connected to the routers/AP and the internet is avalible again. Where to start on this i don't know. Thanks for any advice i can come by.
