I am a college kid, and I live in a dorm room with a roommate. My roommate has a router, which I haven't used up until this point. We are provided 2 ethernet ports into the wall. He connected his router to one of them, and I connected my laptop to the other. Things were joyous, etc.
Suddenly, upon returning from spring break, I find that I cannot connect to the internet with my ethernet cord; it says my cord is unplugged. I can do so just fine on wireless (the roommate's router). The bizarre thing is that when I unplug my ethernet cord from the wall and put it into my roommate's router-- wallah! I have ethernet-internet. I made sure my wireless was off to test this. When I'm plugged into the wall, I get a flickering between "enabled" and "a network cable is unplugged." The lights on the ethernet port flicker in time. I have tried swapping the ports on the wall AND turning the cord around. Same effect.
Edit- I have a desktop that does not have a wireless card. The ethernet-to-wall option works JUST FINE for that PC.
What could be causing this? To my knowledge, the school has not implemented any requirement for routers, and we have not changed anything. I like ethernet more than wireless because of stability, and I might find myself without a roommate at some point. Does anyone know of a fix for this?
Edit2- Here's what I did to test after browsing this forum a bit:
