Hey guys. So, I get together with my friend often, and we normally go to the same persons house, and when we do, I always bring my MacBook Pro, for entertainment. About 3 months ago, my internet worked at his house. His dad changed the wireless password, and since he did, the internet doesn't work. I'm picking the right network, and entering the right password, because we tested it on a PC. So, I was wondering if anyone know what's going on here. They didn't change their internet system, they just changed the password, and it doesn't seem to work on macs ever since. Unfortunately, I'm not at my friends house, and I'll probably be going in about 4-5 days, but I was wondering if you guys can give me tips on stuff I can do when I'm there. Thanks!
