I have an older generation Airport Express (it's the one before the current gen). It was working completely fine until one day I couldn't connect my phone to it. I have a nexus 4. I reset my phone, upgraded to Android 5.0, but still nothing. It says connecting for a while and then it says network avoided due to poor connection. I reset the Airport Express multiple times, but it still didn't work. I can connect my iPod touch and my Mac, and they work fine. I tried connecting my Amazon fire stick TV (Also running android), but that didn't connect either. I tried changing security settings, password, network name, etc. One time when I was setting up my Airport again, my phone connected to it (It was broadcasting as Apple Airport Express and the light was solid amber, so it wasn't set up) and was working fine (my Mac could also access internet during that stage). As soon as I gave it a network name and Airport name, it stopped connecting again. It's such a weird issue, and I can't find any solution online. TLDR: Airport express won't let me connect any android devices to it after I set it up. Apple devices work fine. Does anyone else have any other ideas I can look into? Thanks a lot!
