I went with Costco Orbi RBK 753 and extremely satisfied, no speed loss at wireless satellites. No reboot needed for almost two years. Just ask yourself why the Orbi is almost doubled the price but Costco still offers them?

Blows it away in terms of value to performance.

The M9 offers an overall higher potential maximum throughput by having a third band (5Ghz fall over and dedicated wireless backhaul.)
Not knowing your specific network and usage profile, generalizing, the average 3-4 person home user will not notice a difference between the two.
That said, the M9 is your go-to choice if you are going to use wireless backhaul between the APs as the M5 (dual band) has to share the 5Ghz band between backhaul and user traffic.

Google is your bestie for more details (examples:)

I have this one on office but the app says I have latest fw but it's dated 2019. Any idea?
Yes, the app isn't very good. Grab the latest version of FW from the site directly: https://www.tp-link.com/us/suppor.../#Firmware

Quote from seeker :
I think I'm one of the ones with a bad system. My M9s will lose connection at random times. I've tried switching which one is the base and it was the same issue. Modem still working fine and internet on computer connected by ethernet still working. Someone had to get a bad batch
What does that mean, M9 will lose connection? Using wifi backhaul and a remote M9 disappears or drops or specific wifi devices drop? If the later, did you try disabling "fast roaming"?

How does this compare to the NETGEAR - Nighthawk MK63 AX1800 WiFi 6 Mesh System includes Router and Two Satellite Extenders for $170 and is available in store?

https://www.costco.com/netgear---...36361.html
I bought the nighthawk and I hated it. It dropped signal a lot and I wasn't able to separate 2.4 and 5ghz signal. Ended up buying the x90 TP-Link decos and it's worked great. I was able to set up a 2.4ghz guest network for my smart home devices. I probably would have picked up the ones on this thread if it was on sale then.

It's not really "worth" it to buy a single. They do sell single m9s but you might as well splurge just a little and get a couple more

The link takes me to "product not found" page and it does not come up searching for TP Link or "mesh." Am I missing something or is the deal dead?

Costco pulls item pages when they go out of stock.

Quote from MagicMarker18 :
Not really the best if you upgraded it to something better…
Hehe! It is the best mesh router!! Now I upgraded to TP-Link EAP-660HD (3 of them ceiling mounted) and a Omada OC100 controller, a Firewalla router with IDS and a Netgear POE switch! I no longer have mesh "router" :p In fact my router is not recognized my most people here as "router" and most people probably doesnt even know about APs. So, technically that is the BEST mesh "router" I have ever owned!

I'll have devices say there's no internet connection. That's when I started to look at the modem but the computer connected by ethernet cable is still online so the modem is in the clear. I tried disabling fast roaming. I can't say if I saw any real change with that or not. It is too intermittent and variable that I haven't been able to pin down a reason. And like I said, I tried changing the pucks around in case one was glitchy. I tried adding another one into the system wondering if there was some magic blackhole zone but that didn't do anything. I tried to remove one of the three wondering if it was too congested. Basically nothing made a difference. It works for the most part and is up most of the time. It's when it just stops that it doesn't make sense. It's also not for that long, maybe a few minutes and it goes back to normal. I've always thought there were gremlins in this house for other things. Maybe they're messing with my wifi when I'm not looking.

Will this work as a mech system if I have a Asus gaming router ? Trying to find 2 mesh access points and it seems the asus mesh units don't have good ratings.
