Seems like more and more people are posting the same issue in forums - Networking no longer working on their ATV. For example, mine will not recognize my wifi network anymore... Neither of my ATV's. And I have never had a problem with them before (using an airport extreme base station). I have no problem connecting with other apple devices (mac mini, macbook pro, iPhone, iPad, etc). Tried reseting everything, but the only thing that does it is sometimes allows the ATV to see the network and connect, but it drops the connection 1-2 minutes later. Seems that everyone that has taken their ATV back to an Apple store mentions that the geniuses are seeing several people everyday with the same issue. They get a replacement and it works fine unless they upgrade to the newest software. Has anyone out there been able to fix the issue without replacing?
