TL-WPA4220KIT : The N300 can get the AV600 signal only when it's in the same room
Hello, I just bought the AV600+N300 kit on Amazon to put off the Ethernet cable going throught all my flat and I followed the step meaning I paired them pluging them in the same room first. After that I put off the N300 to plug it in my room which is like maybe 20m away. Sadly the signal can't reach it or is like 0.2Mbit/s. I tried all the plugs in my room and a lot in my flat but it only works when it's really close of the box internet, which is useless.
You may know that I plugged them both directly on the wall.
Moreover, my PC can't detect the wifi. Don't know why. I know it can't work my 5GHz wifi but apparently the one of N300 is 2.4HGz so I don't know why my pc can't detect it
Do you have solutions for my problems ?
Thank you !
