Any recommendations here? A broad question I know. I've had mixed experiences so far. Most recently tried a Mercusys H80X but it seemed it had an issue with my network topology (see image). Basically I had the first H80X in the lounge with a 8 port switch attached with various devices attached. This was connected to a CAT 6 outlet going back to the hub. All good. The device insisted on having me use enforce modem mode as it wanted to take the role of router over from the Hub 4, fair enough. But for whatever reason, this resulted in two other switches with devices also connected via CAT 6 to the Hub 4 to become inaccessible. I tried numerous things to remedy that, no joy. I'd read the Hub 4 only supported one port in modem mode (not sure if that is true) but tried in router mode with WiFi and DHCP turned off and nothing doing
I used BT WholeHome WiFi (Wifi 5) a while back. They also expected to get a WAN address via the Hub 4 in modem mode but would work regardless provided they could reach the Hub 4 via wired backhaul (You just got an error saying it couldn't get a WAN address).
So I what I am looking for; a WiFi 6 mesh that I can basically just attach to as is to the Hub 4, that doesn't care about getting a WAN IP provided it can backhaul to the Hub 4, and won't stop two thirds of my network from working. BTW the reason I want to move to WiFi 6 is I work with large files at times and the WiFi 5 performance to my server via the Hub 4 is dire.
