I have done a search but didn't find quite what I was looking for. I'm using a 2012 macbook air with OS Lion. Quite frequently when my macbook wakes from sleep it does not connect automatically to my wireless network and when I manually choose the network it then asks for a password. I enter the correct password and have to press 'submit' maybe 10 or so times (as it always initially thinks the password is wrong) before it lets me in... I'm not quite sure what is wrong? When I sign in to the network the 'remember this network' box is ticked and the password is appearing correctly in keychain access. Can anyone help?
