I just moved into a student apartment which has internet included. There is an RJ45 jack on the wall I am I able to use internet normally when using an Ethernet cable. However, I can't share the connection wirelessly. I have a Buffalo ADSL Modem/router which I would like to use to share the connection. The first time I plugged the cable into one of the 4 LAN slot, I was able to browse wirelessly but after a few minutes it stopped working and has not worked ever since. Could it be some kind of restriction on their part? Is there any special configuration settings to share my connection in such a way? Note that I don't use any DSL (phone) line here, I only have access to an Ethernet cable. When trying to browse Chrome gives me "Cannot load page because the DNS lookup failed"
