I set up my tp-link range extender RE 300 with my Wi-Fi Network. All four lights solid-on on the extender.
How do I know if the extender is working and providing the most powerful range?
Also, on my iPhone WiFi settings, I have two Network name Wi-Fi and Network Name Wi-Fi_EXT. The latter does not want to connect and switches back to the Network name without _EXT.
Did I do anything wrong when I set up my range extended.
