NETGEAROrbi Whole Home Tri-band WiFi 6 Mesh Network System (RBK852) – Router With 1 Satellite Extender -Security Features - Coverage Up to 5,000 sq. ft., 100 Devices - AX6000 (Up to 6Gbps)

I have been using my Orbi 750 system for years with 3 satellites. The last couple years, I have 1G Xfinity service, which they upgraded to 1.3G. Unfortunately, the 750 router only has a 1G ethernet port. With the high cost of the Orbi systems, upgrading was not an option.I then discovered by chance on a website that the Orbi 750 and 850 systems are compatable with eachother. I could just change the router and keep my existing 750 satellites. Of couse, the 750 satellites are limited to 1.2G speed over 5 Ghz, vs 2.4G for the 850 satellite. It is still an upgrade in speed and not I was able to replace one of the 750 satellites with the 850 that came in this set.I was able to verify that I now have 1.28G internet connection at the router. My speed tests performed at all locations in the house improved. Of course, the area where the 850 satellite is has a much bigger imrpovement. I am aware that I am still using Wifi 6 (802.11ax) vs the newest Wifi 7, but I'm not willing to pay close to $2K to make that upgrade yet for just a couple of devices I have that are Wifi 7 capable.Also, I bought this item as "like-new" from Amazon Resale for a significant discount. The box had been opened, but the router and satellite were brand new. The Netgear stickers that sealed the bag were still intact and it was impossible for me to open the bags without tearing the stickers.I was so happy to find out that the 850 works with the 750 system. I was able to upgrade my system to take advantage of my 1.3G Xfinity service.

Got the used like new option and I am extremely pleased. The product arrived in a nice box, the router and satellites were labeled and had their QR code on the front, each one with its padded bag.The set up was super easy and now we have strong internet outside the house.I primarily purchased ti get WiFi down to a shed around 120 ft away from the house/router without having to wire it. The system works perfectly and now I get full WiFi down at my shed (the house is elevated compared to the shed and there are trees in between), I would highly recommend it to anyone. Also highly recommend the used like new option the seller did an amazing job! Included picture of the shed from the house.

I try other products. For example, tp link. I could have a really bad experience. constantly cutting off, not working properly.(After I installed 970. Everything works flawless. very good product. (Only Downside problem. application does not have. lots of features It's basic but it's working) Would be great If it has other controls without paying extra. but overall I would still Recommend this product. if you have lots of devices. especially for business no brainer. of course, coverage range. Wonderful. connectivity. Very good.

Pros:- Speed, speed, speed. Best WiFi speeds I've ever experienced, I routinely hit peaks at 800MBps+ (see pic) => +5 starsCons:- Web interface is excruciatingly slow, counter-intuitive and cumbersome. The previous Orbi generation web interface was already pretty bad, but this is worse, the new Orbi supposedly comes with a much snappier CPU and should run the webserver a lot faster, but it doesn't. To add insult to injury, Netgear removed a ton of options readily available in the Orbi first generation => -1 star- Security is not implemented well, the thing leaks like a sieve (see picture, you absolutely don't want the blue squares). I would caution against connecting the router directly to your provider's WAN, you might want to leave a gateway or a cheap yet capable router in the way. That's using the latest firmware available (V3.2.9.2_1.2.4), and with the firewall settings on ("Disable Port Scan and DoS Protection" is off, it makes no difference on or off anyway, I tried both) => -2 starsI own the previous generation of Orbi router/satellites, they are far from perfect, but they are rock solid and reliable when it comes to security. This new product was obviously rushed to market, and consumers are essentially being used as beta testers. Given the amount of similar reviews all over the interwebs, I'm surprised Netgear is not stepping up, the firmware in its current state is either going to lead to extremely negative headlines when someone manages to exploit the security holes on the WAN side, or to a class action lawsuit for selling an unfinished product and not implementing what their website says they did. Netgear keeps saying here in the comments they provide high security and point to their website security "good practices", but they haven't even implemented the first "security measure" listed on their site.I'll come back and update my review as they make progress, in the meantime, I'm putting my RBR850 behind an el-cheapo router with a standard firewall stack (it doesn't take much effort to implement, but I guess it's too much to ask from Netgear for now). This is disappointing to say the least, especially when you have to drop a grand to get a router and 2 satellites.*** 2/24/2020 update ***I did submit a case on the Netgear support website (per their request in the comments), and also pointed out the security issues on their forum. No peep from Netgear, so that's another star that's gone. Some forum users acknowledged they saw similar issues with the built-in firewall, but Netgear reps never took the time to look/respond at the forum either. I gave up and bought an Edgerouter 4 from Ubiquiti and switched the Orbi to AP mode (access point only). The Edgerouter proved to be rock solid and secure, though if you plan to make a similar move, make sure to triple-check your firewall rules on he router before you make the switch. It's unfortunate I had to spend another $200 to get basic security that was available in the previous Orbi generation. One positive note: the guest network in AP mode still works, it has its own subnet and dhcp, I was actually surprised moving to AP mode didn't screw that up (one can argue since guest devices are on a different subnet with its own dhcp, they're effectively being route, so it's not true AP mode for them, but that's the way it should be designed to keep the guest network isolated).*** 3/1/2020 update ***I keep finding new bugs on a regular basis. Latest one: if you plan to use the router in AP mode and plan to use a fixed IP address for the router instead of DHCP, the router will not connect to NTP servers to get the correct time, even if you try to use a third party server and not Netgear’s. Why does it matter? Many devices will not properly connect to WiFi guest due to the fact that the guest network has its own DHCP server (it’s on its own VLAN), I suspect the leases are out of whack due to the time discrepancy between the router and the devices.*** 3/18/2020 update ***Netgear pushed a broken firmware last week and essentially bricked many Orbi's in the process. See Netgear forums, lots of unhappy users over there. We're well into negative stars territory at this point.*** 4/1/2020 update ***Well, I really gave it the old college try, but I eventually gave up and put the thing for sale on fleabay. The hardware is great, but the software is simply not mature enough, and I have better things to do than debug the damn thing on behalf of Netgear. I switched to the Amplifi Alien and things have been rock solid since then. YMMV.

We purchased our forever home 2 years ago and have struggled with WiFi coverage. We purchased google home, placed 4 nodes throughout the home, upgraded to the best internet package with our provider, and still had spotty service with constant drops. Orbi was a game changer. Speed test show a 500% increase!!! Thanks NETGEAR!
