Hi,

I currently own the TP-link AV500 Powerline adapter (TL-WPA4220T v.1). I have had it successfully connected to my router for about 1.5 years through the Powerline without running into any problems. Recently, the wifi has stopped working for mobile devices. All other devices (laptops etc.) work just fine. When they first connect the wifi works well for about 10-20 seconds, but then suddenly stops, whilst remaining connected. To troubleshoot this I have reset the Tp-link adapter, as well as my router, multiple times. Note that the wifi works fine on all devices when connected to the router, it's only the extender. I know the problem has nothing to do with range because I currently work right next to the adapter.
Is there any way of fixing this?

Thank you.
