Airport Extreme and Express Connectivity
I have been using an Airport Express Gen 2 as a wi-fi extender for my Airport Extreme base station.
A few weeks ago my Internet connection went out. It came back when I unplugged the Express. I tried to re-connect it again with the same results. The Express is showing that it's in need of a firmware update. But I can't download the firmware because when the Express is plugged in I have no Internet. I can connect the Express by Ethernet to do the firmware update, but I'm reading that the current firmware performs poorly on the Express Gen 2. Any advice would be greatly appreciated. I need the extender as there are areas where I need Wi-Fi where the signal is now weak without it.
