Fwiw, unifi can also do mesh. I have a temporary setup in our new home until I can pull wires which has an ac 6 pro wired to my router, and a 6 long-range in our bedroom and nano ap in the garage wifi meshed. They just each have a Poe ac adapter powering them but they are meshed to the 6 pro. Prior house each was hardwired cat6, and house prior to that I had only 2 of them but used coax moca 2.5gbps to the second one. All setups worked great.
If you have a home with brick wall or concrete wall or just a larger area I would get something wifi 7 capable. I replaced my 2 Google nest pro which I had setup as a wired mesh system with a single Ubiquiti UniFi Express ux7 and it’s been incredible.
I use mesh routers with a wired back haul it’s great. I have Unifi express 7 on each floor
Can confirm. Last week I decided to connect a smart TV, an Apple TV, and a satellite VCR to a UniFi Express with a wireless uplink to an U7LR in the same room. Only because all those devices are on a movable piece of furniture so I didn’t want to use a cable. Works like charm.
Mesh will have a potentially hard time with the concrete, wifi simply doesn't penetrate - so mesh will be problematic - placement would be key, the satellites need to have a good signal from the base to work well. You might get away with it by placing them near doorways etc. Many people use ethernet along the base of the walls, over doorway frames etc. and wire access points. Mesh systems do have the advantage of a central controller for the access points, so if you can wire them, your wifi experience would be a lot better. I am not a fan of Netgear, TP-Link Deco is popular in this sub, as is Eero (but there's the fact that it's Amazon and has a semi-subscription model. If you want to be a little more spendy, Ubiquiti UniFi has a great interface and good quality that should last. The UniFi Express models have a built in AP and can be meshed. The Cloud Gateway Ultras would be ideal with multiple access points placed around. (I am a UniFi fan) Asus is also mostly well thought of. I think the TP-Link Deco line would be the most affordable choice.
It's really not a lot worse that something like Asus, who has a decently robust interface (lots of consumer stuff hides everything behind "simplicity"). The payoff is reliability and a long service life (my oldest UniFi AP is 7 years old, still supported, and still working great.)
Just so you know, mesh doesn't bring roaming to wifi - any APs set up with the same authetication configuration (SSID, passphrase, security method) will allow wifi clients to roam amongst them as needed. Mesh uses what setups like Ubiquiti UniFi and commercial networking hardware use to allow *faster* roaming. UniFi would be my recommendation. It doesn't matter what your brother in law thinks.
In consumer world - Asus and TP-Link are the better choices. Eero is great hardware has a subscription model for some needed (IMO) features. I would avoid Netgear, D-Link and Linksys - they are not what they once were and have subscription models, sometimes poor support, and varying reliability and quality. You could also consider gl.Inet Flint devices if you're looking for an all-in-one router, they have gained a very good reputation. I agree that a better choice than any of the above would be Ubiquiti UniFi and TP-Link Omada is also decent - it's different than the consumer gear. Reliability is one of the major points of these prosumer setups. I've been running UniFi for 7 years, it's great.
Whats your budget? Unifi is good in that you can combine the network and cameras. Ie with UCG Fiber, or UDM Pro if you have a rack.
Well it depends haha. UDM Pro is good if you have space for it. It can run protect for your cameras and storage will be on a single HDD. UCG Fiber is good in that it outperforms the UDM Pro (if your internet is fast enough) BUT storage for camera footage is limited to a single NVMe SSD and usually cost as large ssds are expensive. Whereas you can get fairly large 3.5" hdds which are more suited for repeated writes. Then you got the others like the UCG Max which is like a lesser version of the ucg fiber. UCG Ultra will only run the network side no protect app to run cameras. Then theres always UCG Fiber and UNVR Instant to run the cameras. Unifi will adopt Onvif cameras but you wont get any motion detection without an Ai port. If you already have your own NVR then you can just get whichever router can sustain your internet speed. How fast is your internet speed? Are you able to have wired ethernet to the access points?
I personally would get the UCG Fiber and the U7 Pro XG (or even the U7 Pro Max) the Pro XG has a 10gbe connection but without a 10gbe switch its not fully utilised. The U7 pro max has a 2.5gbe interface which would mate well to the USW flex 2.5 8 port poe switch. Even then the U7 aps might be too much if you dont plan to be using all that much bandwidth.
I believe most routers will handle 30 odd clients/devices if theyre in range. If you need more range in different areas ideally you would have multiple access points. Eg a mesh system. Multiple access points with a wired backhaul (feed back to main) is the best as its not sharing bandwidth with itself. I run a unifi system myself but that is more prosumer grade. If you want a more basic solution they have those as well. If your internet connection is not very fast a better router wont help. What internet connection do you have?
