Hello,

I have a 3rd Deco XE75 unit I don't need (after buying a 3-pack, I only needed 2 of them for my home). The use of the 2 units has resolved an issue with wifi coverage/reach in my home. I'm curious if the 3rd is usable on its own to extend wifi coverage/reach.

My parents' have an AT&T U-Verse 5031NV Modem/Router. Their home, almost the same size as mine suffers from the same/similar wifi signal "reach" issue in certain places.Therefore, my question is: Could using this 3rd unit as a single, standalone router/modem replacement, (in passthrough, just like I did but with their modem instead) improve their wifi signal over their current router? Or is wifi signal "reach" only improved when you have 2 Deco units set up (like I have in my home)?
