I took my MacBook Pro to work today and couldn't connect to wifi so my IT guy took a stab at it and we gave up a couple hours later. Come home and fire up my laptop only to have my router ask for my password when connecting. Type in my password, it "connects" but I can't browse. Come to realize that all the networks I've connected to are gone and all the 802.1x profiles are deleted. Needless to say my IT guy is a douche. All my other devices (2 desktops, 2 laptops, 2 iPads, ipad mini and 2 iPhones) still connect to my router so I'm pretty sure that's not the problem. How do I fix this? Wen I try to create a new 802.1x people, it asks for a user name and password but I've never had one in the past. Help!
