I updated my Airport Extreme a couple of weeks ago and have been dealing with a flashing orange light on it ever since. I've looked on the net but nothing is solving this problem. I updated it to the latest version which is 7.5.2. I'm assuming everything works as good as before but I get a popup from time to time telling me there is an IPv6 Relay Error and it's just annoying. Anyone experience this or know how to fix this?
