Hello all, I have a 2012 Macbook Air and I'm having connectivity issues. About 2 weeks ago it stopped connecting to my internet. It forgets the password and insists that the password I'm putting in is incorrect, even though it isn't. The password is definitely correct, I've checked over and over. Other devices work fine with the network and the Macbook connects to my mobile hotspot. On a few very rare occasions I open it up and it's connected. I use it, close it, and when I come back to it it's disconnected again and wont recognise the password. Any idea what the problem is? Cheers!
