I wasn't sure what group to put this in. Only Firefox can access the internet. The other browsers don't work, some games will update, but they won't log in to the actual game. Other games won't even update at all. When it first occured, Steam and League of Legends did not work. But I was able to play Warframe just fine. Today, everything but Firefox no longer works. I checked if it was a setting dealing with proxxy servers, but that wasn't the case. I also don't think it was due to an update because it didn't mess up all at once, and I don't think there was an update at all unless I missed it. Any help is appreciated.
