Extender stops working, all LEDs are blue
I have a Tplink Archer c20 router and a new Re305 extender. Previously, I had the tplink WA850RE extender as well (which also had the same issue which I'll describe below).I have paired my extender with the router using WPS.
My Internet is working fine, I have uninterrupted connection when I'm connected to the main router. My issue is when I am connected to the extender. All 4 LEDs are always stable and blue. Devices successfully connect to the extender but after a while (anywhere from 2hrs to 2 days) the Internet connection is lost and I'm unable to browse any website. If I switch off WiFi on my device and try to reconnect to the extender - "unable to obtain Ip address" error is shown.
If I connect to the main router, its working fine.
If I switch off power supply to the extender and turn it on again then it starts working properly. For a while. After which I again get into the not working - reconnect - no IP address loop.
I have connected to the tether app and both router and extender are on latest firmware.
