Deco XE75

Yeah before we got Bell we already had a Deco XE75 mesh system so we are continuing to use that for better WiFi coverage, setting up bridge mode was a pain but it's been painless operation since then.

The XE75 will only be faster if it can get a signal on 6GHz to the node. It's much easier to block a 6GHz than a 5GHz signal

Same, 4x Deco XE75 around the three floors of my house and no connection issues with my cameras.

I bought a set of 2 used XE75 Decos for $110 shipped. They're fine for my smaller house & detached garage. The website claims the 2-pack covers up to 5,500 sq. ft. Realistically I'd say it's half that unless you have a giant open floorplan. I do like them alot. I can't speak about any of the other systems because I haven't used them. Triband will help, but alot of walls really limits the 6ghz signal. I can easily get 500-700mbps on most of my property. My fiber is only 300/300 so this is just fine for me. Gigabit speed really only works on the 6E if there are no walls between you and the Deco. It's limited to 940mbps or so due to the gigabit ethernet port.

They make a version of this with 2.5gb port - the XE75 pro. I have 2 of the XE75 gigabit models and yes transfer speeds from ethernet port are limited to about 940mbps. I'm underwhelmed by Wifi 6E in general due to range, but it still does really decent backhaul speeds. I'm considering buying 1 XE75 Pro to use as the main node and keep the XE75s as satellites. But I don't have gigabit fiber currently and it would be way overkill for my setup.

You said that you get pretty good coverage with your current router, but how are the speeds? I would go on a limb and say you're only getting 2.4ghz reception in large areas of the house and low throughput (<30mbps) Have you done any type signal testing in your house? Properly placed mesh nodes can effectively extend your 5ghz range to a much higher speed throughout the house while eliminating your dead zone. You should have no issues getting 300mbps with either of those options you mentioned. Getting too much above that you will begin to see the limitations of wireless backhaul, but realistically you should be able to see 500-700mbps in many parts of your home. I have 2 of the the XE75s (not pro) and I do think the 6ghz is a poor performer for backhaul with walls, but performance is still surprisingly good. If I could redo I'd probably go with a non-6ghz triband. Here is a comparison of the different Eero 6 devices [https://powermoves.blog/wifi/eero-review/](https://powermoves.blog/wifi/eero-review/)

And even if you enable 6ghz, it will still use it. Xe75 uses 2,4/5/6ghz same time for backhaul. You can see this if you look from deco app the second xe75. I confirmed this, I can get almost full bandwith from my 1000/1000 connection from second xe75 wireless backhaul.

Wifi 5 is 12 years old, don't buy it. Wifi 6 is the minimum you should buy. Wifi 6E adds 6GHz support, Wifi 7 adds some features for higher efficiency. Tri-band operation isfairly important for good mesh performance, that leaves the 6GHz band open for your clients and 5GHz can be used for the connection between units. A 3 pack of Deco XE75 are 226 euro, I would go that route. Should be comparable to the Eero Pro 6E units. https://www.amazon.de/-/en/Deco-XE75-Tri-Band-Comprehensive-Protection/dp/B09ZRY9YHB If your house has coaxial cable purchase some Moca 2.5 adapters. Using them to create wired links for the mesh network will substantially improve performance.

I just bought the tp link deco xe75 pro on amazon, they have a 20% back of using prime Visa card. Otherwise the Xe75 non pro is identical minus no 2.5G port.
