IrvSp, Thank you. That helps tons.

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...

I am trying to setup my new Archer AX21 router. Should I turn off my old router (Archer C9) before I hook up my new router? Thanks
