Only one user can access internet

[floflorence]

I just recently upgraded my Imac to mountain lion. Everything seems to be fine except that only my user account can get on the internet. The other two user accounts cannot get on the internet. Any ideas as to why this is and how it can be fixed? I have tried searching for anything similar to this and I can not find anything on the subject. Any insight would be awesome!

Similar Problems

I have the same problem, only in my case one user account can't connect (or the connection is incredibly slow) while all the other user accounts can. This also happened to me about a year ago when I first bought my imac. After spending hours on the phone with Apple support the only solution they could come up with was to reformat the computer and reinstall the operating system. At the time that wasn't such a big deal since I didn't have much on the computer. Now that the problem has returned I really don't want to have to do that again. After searching on the internet I've noticed that this problem seems to be more prevalent on Window's computers. Certainly Apple support seem to have no idea what 's going on. If anyone has a solution please let us know.
