Ok so I purchased the A7 ac1750 router. It works awesome I just bought a TpL WiFi extender AC750. Just because sometimes upstairs kinda buffers a little. I'm hooking it up, I can see the network name of the extender on my phone network WiFi list but wants me to put a new homename & PW! Do I put in the same password as the router that I already have set up on all my devices or do I have to create a different one just to hook up to the extender? Please help
