Airport Express keeps losing connection
I've been running an airport express for a few months, streaming music to my HiFi. Recently, it has started dropping from visibility - I can't stream to it, even though the green light is solid on the device. When I run airport utility, it can't find the airport, no matter how many times I rescan. I need to hard reset and reconfigure the airport to get it to work - but then it disappears again after a short while (minutes). I've seen similar issues raised on forums, but no conclusive solution. I've already tried:
- setting static IP
- changing to WPA wireless security standard
- changing wireless channel
Nothing seems to work... help!
