I'm using an ethernet connection from school. The first time I connected the ethernet cable to my laptop it worked fine. I took my ethernet cable out to untangle some wires, then when I put it back in the internet stopped working! As of now I can only connect to my college's wireless network with internet which is hideously slow. When I put my ethernet cable in it just does nothing. It's like it doesn't recognize it anymore!
Any help is nice,
p.s: I'm using Norton Antivirus Trial that came with my laptop. Can this be causing a problem? My internet worked before with it installed, but who knows?
