I have an existing wifi which I want to extend to the garage. I have paired the powerline plugs and used a web browser and tplinkplc.net to change the powerline wifi name to the same name as my house wifi and the same password, though I could not save the password because it said "timed out". I also managed to add a guest wifi with a different name "EGAcupuncture" with no security. When I plug the 4220 into the garage, it shows connected, all lights on except ethernet (I am not using that). I can connect to the guest network fine, but when I try to connect to the home network it times out. The signal on the guest wifi is very strong, the signal on the home one is much weaker, but then gets strong, then disappears. I have a feeling that
1/ the weak home signal is not from the Powerline but from the house (there is a very, very weak signal there)
2/ the strong home signal is from the Powerline but for some reason when it connects it disconnects, and I am wondering if the "UNIFYING" of wifi should be more than just changing the wifi name and password.
3/ the guest signal is always strong and works as well as I would expect over that distance... but this is only for guests, I don't want to be on another wifi as it affects ability to attach smart home devices.
Any ideas why this is happening and what I can do to get my Orbi RBK50 router and the tp-link to play nicely together?
