I’ve been using a Netgear Orbi RBE771 for a year and have had zero issues. Dedicated wireless backhaul channel works great
This is my response from a different thread but this applies: A sample size of one but I wanted to give you my perspective. I used to have RBR50 with 1 satellite with wireless back haul. I get 1.2GBPS at from my ISP. I used to get really good speeds (5-600) everywhere, but about 2 months ago it started getting worse and eventually died. I’ve had these for 5-6 years so I got my money worth. I bought Deco BE11000 and had it for a week. I hated it, it was unstable and the internet speeds were all over the place. Compared to my Orbi, I got higher speeds (800 deco vs 500/600 Orbi) when I was close to the router, but worse speeds (80/90 deco vs 200 Orbi) when I was far away from the router. Some of my smart devices didn’t even connect at all. My work computer kept on dropping connection constantly even at 15 feet! Then tried the 770. The firmware was a mess. Constant dropping connections with several drops. My TV which is about 20ft away kept on losing WiFi and it drove me crazy. Specially at the price of 770. I finally went back to RBK752P and it’s been a dream. I get 800+ pretty much everywhere in the house and connection has been rock solid. Take that for what at worth!
Tp link deco or Orbi 770, wired back haul - I have the same situation and got the 770, now I get a full 1.5gbps on all floors every room - put one mesh point on each floor (wired).
You probably want a mesh router. This means that there are two or three routers in a pack that all connect to one another automatically to keep your signal boosted. Go with TP Link Deco or Netgear Orbi 770.
Nice. I thought about the 970 but I’m the only real high usage person in my household, so I went with the 770. It covers an entire 2 acres of my property and I can get a 100mbps signal 1/4 mile down the street (probably a fringe case because I live at the highest point in the neighborhood lol) People like to crap on the 770 but it’s a real nice mid tier solution.
You are required to keep your ATT gateway. There is a technical way to bypass this involving by cloning your ATT modem onto a piece of hardware that "tricks" ATT into thinking you are using their modem. The 2 much easier solutions are either 1) put your ATT gateway into ip passthrough mode, or 2) setup your mesh network as Access Points instead of routers (AP mode) I have the same ATT gateway on 300mbps as you. I went with 2 Orbi XE75 mesh units which give me great speed throughout my house and yard. I did realize that I probably could've moved my modem to the center of the house with an $11 ethernet cable and gotten OK results instead. But I do like having the full 300mbps that I pay for all the way in the detached garage.
Avoid Netgear at all costs. They appear to be incapable of getting the firmware right for their WiFi 7 units. I got an Orbi 770 and gave up. I went back to Eero with the Pro 7. Back to stable WiFi.
Apple compatibility should be nothing to be concerned with. All this WiFi crap has to meet standards or nothing would talk. Your biggest issue with mesh is getting good WiFi paths back to the router. With mesh, you have two WiFi problems -- Client to mesh node and mesh node to router. Most people will recommend that you eliminate the mesh part and wire the connection from node to router for best coverage if you're able to. It's also generally cheaper to do this since you can get a simple AP setup. If you can't eliminate mesh then you should get something that's WiFi 7 and uses both the 5Ghz and 6Ghz bands (the Orbi 770 is tri-band so it does).
