Okay, so I've moved into uni and i'm trying to get my wifi sorted;
I have a macbook air, and the router is: Tp-link 300Mbps Wireless N Router
TL-WR841N
I have already tried a D-link router that didn't work, I then bought the Tp-link that also didn't work, and the IT guy who came round went and exchanged it, then he tried to install the current one, and then two of them tried to figure it out for half an hour, and then it was fixed, but I don't know what they did, and I just hope someone has an answer this late at night.
I can connect to the wireless, like my little bars are full, it's just the actual internet connection and system preferences confuses me so if anyone knows where to start (apart from turning it off and on) I've been trying since Thursday with no luck, tia
