Airport Express error 10053
I use the Airport Express only to stream music to speakers. I have recently updated my router and all the wifi settings have changed.
I managed to update everything using Airport Utility on the laptop (Windows 8), the light is green and I can see it is connected to my wifi on the manager of the router.
However, none of my devices can see it - iphone, ipad, laptop.
If I try to change any of the setting on Airport Utility on the laptop I get a message saying "error 10053".
If I use the Airport Utility app on the iphone I have an orange triangle saying "Device not Found".
I have tried all kinds of resets and turning everything off and on again.
Please help.
iPhone 6, iOS 9.2
