Powerline TL-WPA7517 only works while attempting to pair
My kit arrived today, after following all the recomendations i found in the manual and online i just can't get the extender to work properly, i tried to pair them in the same room, didn't work, both power led's just kept blinking for 2 minutes, but all ights in the adapter are on so i think the adapter is working as intented if i try using it even without pairing i get a superbly inconsistent connection (powerline and ethernet light turn off and on on the extender every minute and i only get connected to the internet for like 5 seconds) , i tried using it also with a adapter from a tenda powerline (which works fine but due to one of the plugs beeing internally damaged i get packet loss when starting to use high download speeds, thus having bought this tp-link kit) but i get the same result.
But when i press the pair button on the tp-link extender all lights turn on (powerline, ethernet, wifi), power led keeps blinking as its trying to pair and i get a perfect connection during those 2 minutes, low ping, max download speed, no packet loss, but after the 2 minutes pass and the power led goes back to beeing on, and all goes to sh*t again and i get disconnected (same happens if i use the Tenda adapter instead of the tp-link adapter) which makes me belive theres something blocking my connection in the tp-link extender.
Has anyone experienced anything like this?
