I think I need to ask about the way this device works. It is giving me behavior that is outside of my experience. I bought the EAP225 to extend wifi to our living room. We have Verizon FIOS coming in through the eaves of the house, with their router upstairs, and we have ethernet cable connections throughout the house.
I am replacing a TP-LINK Archer c9 router that predates the Verizon router... when we got the Verizon router, we set up the Archer as a wifi AP and switch, and it worked for a number of years that way. It started giving us trouble recently, and it seemed to be related to the router side of the device.... So, we decided to switch to a dedicated Access Point.
Installed the EAP225 yesterday, and it did not behave the way I expected. I expected to set up Wifi access the way you would on a home router, with me assigning an SSID name, and a password. It gave the illusion of letting me do that, but the SSIDs I created were not visible from my laptop or phone. However, I saw two new SSIDs that were TP-LINK names, and they corresponded to the SSIDs on the back of the device. They also allowed access without submitting a password of any sort, and I am worried that everyone in our neighborhood can use our wifi.
As I read up on the how APs are supposed to work, the descriptions seemed to be indicating that the AP should be adopting the identity of the Verizon router wifi upstairs. So, as you move through the house from upstairs to downstairs, you really are just logging in on the upstairs wifi... But why no password query? I have tried making our laptops and phones forget the login, but it only seems to work for the Verizon router upstairs.
