I've changed my router from Archer C1200 to Deco M5. I connected cable for DVR to one of my Deco M5 devices. Unfortunately, it was not connected & I can't view the CCTV. Appreciate your kind help....

@matthew.mfden Thank Matthew for your kind response. Noted. Can it be used as an extender if I connect via LAN cable?

I just installed a new Deco M5 router & its works. My old router AC1200 still ok & I want to use it as repeater or range extender. Can it be used for that purpose? If yes, appreciate your kind...
