I'm doing all this from my iPhone right now, I'm in college and was using the computer when I disconnected the ethernet cable BAM I put it back in and no Internet! I plug it into my roomates Jack and I have Internet. So I go out and buy a new eathernet cable thinking it's that plug it in nothing! Go to my roommates room (who is on the Internet) and plug in my computer no Internet. Then he can't get Internet.. So I do the ipconfig /renew and it says no opperation can be performed on local area connection while it has media disconnected. I called the university service desk and they said they would get back to me today but it's vet's day and their all enjoying the day off!! I have so much work due at 11:59 pm.. PLEASE HELP if you can talk over phone that would be great!! I can't type much more on my iPhone lol!
I don't understand how this could of happened. I was on the internet and I unpluged my ethernet cable and pluged it back in about 2 min later and i had no internet and no ip. i then asked my roomie if i could try his internet, keep in mind he was on it, then unplugged his cable gave it to me and i was able to go on the internet. so i figured my cable was bad (its in rough shape) so i bought a new one. I plugged it into my room and still no internet. So it cant be that the cable has anything to do with it. So i tried to access the internet in my roomates room again and their was nothing. Shortly after he plugs his into his internet that was working just fine a second ago for him and now he has no internet aswell.
So I guess, this is the part of the university service desk. They have to check on what happens. Could be a port on their switch or whatever. They can first simply check on the switch, whether there is a link, when your computer is connected and swiched on.
If there is a problem with the switch, your wall plug is connected to, you might not get a link and in that case, you have no connection to the server, that provides DHCP to assign the IP address to your computer.
Such switches are located in their server room or there might be another location at the campus, where additional switches are located. If these switches are manageble, they can check them right from their desk.
