I am a real newbie at this stuff. Sorry if my questions are too simple.
I bought a new AX21 router and I want to replace my old router (TPLink Archer C9) with it. I would also like to make my old C9 router into a WiFi extender.
Do I just turn off my old C9 router and plug in and setup my new AX21 router. Then what do I do about setting up the old router as a WiFi extender. I would appreciate any details you can give me.
