I just moved into college and only have one ethernet port in my room. This is a problem because I need four and I am not allowed to have a router. I purchased a switch a plugged it into the wall ethernet port. I plugged my computer into the second port on the switch. When my roommate plugged his computer into port #3 his internet will not work but his laptop says connected. What am i doing wrong?? Any help is appreciated!
A network switch does not give 'everything' on it the same mac address. It just allows for everything to go through one line and the switch switches who gets what info/etc hence the name switch. my uni told us we couldnt have routers or whatever, but everyone did. If you have a spare one lying around, hook it up and stuff. Just be sure to secure the wireless if you leave that on.
Youll probably either need to re-register your router's mac address or just clone it from your laoptop/computer to the router. If the university were to find out you had a router (and if they were to even care…) they would firstly just ask you to remove it. They wouldnt go crazy and break into your room and smash the router up. "Hey, we noticed you had a router and thats against our rules, please disconnect it" or something.
