My Airport Express working. Actually what happened was my TV which was connected to the Airport Express by wire couldn’t access the internet (so no BBC iPlayer for me then).
What I couldn’t fathom out was why it had stopped working, as I hadn’t done anything, I hadn’t done any updating, no re-configuration or changed any wires.
It was still broadcasting the SSID, so I first checked the wireless, devices connected to the Airport Express fine, however they got no internet access.
First did a hard reboot of the Airport Express, that didn’t work. So I did try and reboot the router and that didn’t work either. I was using a static IP address with the Airport Express, so I changed that to dynamic and the Airport Express ended up with a 169 IP address, a self-assigned address. So it wasn’t getting an IP address from the router, so I rebooted the router. No joy there.
The Airport Express isn’t directly connected to the router, it’s connected to an Airport Extreme which in turn is connected to the router. The reason is that there wasn’t a spare ethernet port on the router when I added the Airport Express to the network.
In the end I changed the ethernet port it was connected to on the Airport Extreme and guess what? Yes it all started working! So there was nothing wrong with the Airport Express, it was something else; the ethernet port on the Airport Extreme.
I have no idea why the ethernet port stopped working on the Airport Extreme. Well my network’s working now.
