Great info - thanks. A little more detail.

ATT router/modem is 2.4/5 ghz. The 5ghz reaches upstairs but sometime I have the signal drop off. I thought an extender would bring in a stronger signal - it did but at the cost of speed. I was trying a Netgear Wi-Fi Mesh Extender Dual band up to 1200 Mbps. No joy. Going back in the morning. Netgear has another Mesh Extender with even higher speeds and distance but I'm thinking it will still yield a drop in speed since my 5ghz is reaching where I need to go.

How do I know it was connecting? Simple plug in, unplug, compare signals and speed. Plugged in I see the stronger signal but the speed test slows down.

I been told that the modem/router setup is a weak link in wi-fi (can have momentary dropoffs) and it is better to use individual pieces. I looked into replacing the modem/router supplied by ATT but was advised that their Fiber system requires a router and modem they supply (it has to be registered with their fiber system or it won't recognize my modem) and I can't upgrade with non-ATT products. Does anyone know if this is set in stone or is there a workaround?
