Macbook Pro won't connect to wifi
my MacBook pro won't connect to our wifi, it keeps saying "invalid password" regarding wifi, but it is correct. I have tried removing the wifi from the list in advanced settings and rejoining, changing the wifi password, restarting my computer, restarting out router, etc. My wife's MacBook air, our iPad, and phones connect just fine. I read something about it being a problem with the 2.4 vs. 5 issue, but I have no clue what that means. Any advice?
