My main router has a wifi network.  I configured the Archer AX55 to act as an access point. An ethernet cable runs from the main router to the Archer AX55. I used the Tether app to configure the wifi network on the access point to have the same name and password as the wifi network on the original router.  However, the network appears twice and is acting like two separate wifi networks. When using my laptop, I need to choose which of the two identically named networks to connect to.  Does anyone have an idea about what I'm doing wrong?  Since I've configured the Archer AX55 to be an access point, I was expecting the wifi network to behave as a single network everywhere in the house.
