ASUS - ZenWiFi XD6

A big BIFL advantage of ASUS routers is that their firmware is largely based on open source code, and there are open source alternative firmware options available to add features or maintain support for older devices. While everyone else is trying harder and harder to close their system, and giving up on firmware updates for devices as soon as they can, ASUS’s openness gives me a lot of confidence for the longevity of my devices. I have 2xXD6 in a mesh with a wired backhaul and it’s been excellent. Very stable and performant (though my PCs, tv, etc are via my wired network which is always going to be better than wireless).

Asus XT9 (AX 6e) should do the trick. Wired backhaul or dedicated 5ghz channel for backhaul should work very well for your situation, and more than adequate for 1 GB connection. I personally have an ASUS AXE7800 as my main router with two XD6 as nodes in an 1800 square foot house (two-story with basement – basement square footage not included in the number). Also, the XT9 has a 2.5 GB port to connect to your service provider modem, and you can do link aggregation on two of the 1GB ports going to the other router. You can actually easily do two Asus routers together via mesh because it's essentially baked into their firmware. You don't need to get a mesh system, you can either go for prepackaged mesh or just pick up two routers and set it up as mesh. This opens up options if you look for two cheap Asus Wi-Fi 7 routers, although 66e should work just fine in your situation.

You can connect mesh nodes through Ethernet. OP has an Asus router, so they can buy more WiFi6 Asus Routers and connect them through Ethernet to set them up as AiMesh Nodes. My house network is set up like that, and I only have issues when streaming to my phone when going downstairs because it changes nodes, so it lags for like two seconds, and then goes back to normal. Other than that, it's a great experience all around.

It's called a wired backhaul mesh. Look it up. The point of using mesh nodes connected through ethernet is to keep the "seamless" transition between nodes without having any network degradation between them.

Asus with Ethernet back haul. Router + 2 APs. Works great, gigabit access all over the house!

You must have gotten a dud. Deco BE95 system. Simply amazing. Had it for 12 weeks now. Zero drops. 5800 sq ft home. ISP 6 Gig up and Down. Wired backhaul. 121 connected devices. Wired devices that can handle multi gig speeds - 6 GIG WiFi 7 - 2.5-4.3 GIG WiFi 6E - 1.8-2.4 GIG WiFi 6 - 1.1-1.6 GIG WiFi 5 - 600 mbps - 900 mbps WiFi 2.4 - 200-500 mbps The consistency, reliability and speed blow every simple competitor out of the water in my experience! Amazing system and have tried them all! Eero Max 7, Orbi 970s, Asus ZenWifi

The folks suggesting Omada and Unifi aren't wrong. Those are *great* systems, but they're pretty "pro". If you don't need advanced networking features (e.g., VLANs beyond isolated guest networks, traffic rules)/want something that's more plug-and-play, a mesh system that supports wired backhaul might be a better fit. Asus ZenWiFi performs well, supports wired backhaul, and offers some useful advanced settings. It's not as configurable as Omada or Unifi or MikroTik, but it's simpler to manage and "good enough" (multiple isolated guest networks, band-specific networks, QoS) for lots of home users. Eero also performs well but doesn't support as many advanced features as Asus.

Eero (Amazon), tp link Deco, and Asus ZenWifi are all well-reviewed and perform well. If you've got to go mesh, look for a tri-band system with a dedicated backhaul channel (Eero, Deco, and ZenWifi all have models). Eero and Deco are a little more "plug and play". ZenWifi is also easy to set up, and some models give a few more config options/control than Eero or deco. The tricky part is that you don't know how well mesh will perform until you set it up in your place. Two nodes might be enough, but you might need three (or four). A 6 ghz backhaul channel might work, but, if the walls and floors in your place cause a lot of interference, you might see better perf with a 5 ghz backhaul. So buy from a place you can return it, maybe start with three nodes, test how coverage and speeds look, go from there. All three have 2.5 Gbps ports. 3 gig is a *lot* of bandwidth for a residential setup. Unless you're regularly downloading gigantic files (video, game updates), you probably won't exceed ~300-500 Mbps, and WiFi will de facto limit the perf on any device to ~200-600 Mbps. For most homes, 200 Mbps is plenty. If the 3 gig price isn't much different than ~300 Mbps (if you're in the US, it's hard to find service under ~300 Mbps), go for it, but if you're paying a premium for 3 gig, you can save some coin and you almost certainly won't notice a difference in performance. If you're in Europe, you rule!, fiber away because you're prob only paying like €40 for 3 gig.

For a villa that size the easiest fix is to ditch the idea of separate access points with different names and go for a proper mesh WiFi system, since it gives you one network name across the whole house and your devices switch between units smoothly without you noticing; you just connect the main mesh unit to your Etisalat router and place one or two more units around the villa, usually one downstairs in a central area and one upstairs, and systems like TP Link Deco, Google Nest WiFi, or Asus ZenWiFi work well in UAE homes even with thicker walls, so you’ll get stable coverage in all rooms without rewiring or dealing with multiple SSIDs.

I had a lot of issues with the google nest wifi- for the past year or so I have used an Asus ZenWifi which works better for me, and I do have usable network access from my shed which is about 100 Ft away from the house. My biggest issue is getting a signal past the walls/siding in our house- there is 'double' siding because the house originally had asbestos siding, and a former owner put vynil over it. I get by this with a small enclosure holding one node just out side the walls of the house.
