This is a question that’s difficult to answer since there can be so many variables in homes, devices, number of devices, interference, etc. Over the years here, I’ve seen routers or systems that work great for some, have problems for others and vice versa.
That said, I’ve had fantastic results from my Eero Pro mesh system.
Prior to that I had a Linksys EA8300 Max-Stream AC2200 Tri-Band router which I considered a pretty good router. It would stream 4K on two tv’s at once along with lots of other stuff running without problems. However, once I started getting V3 cameras to replace V2, I had lots of issues with the V3’s dropping offline frequently on the Linksys router.
Once I got the Eero Pro system, all the V3 problems went away and everything else also remained rock solid. I am a pretty heavy device and smarthome user. A quick check on my Eeero app shows 64 devices currently connected which include everything from smart devices like bulbs and switches to, computers, phones, printers, etc. I also have 9 Wyze cameras running continuously.
But as mentioned this being a difficult question to answer, I think I’ve seen a couple members here say that had issues with Wyze cams and Eeero mesh system where mine has been the best I’ve had. I particularly chose it because each node on the mesh was supposed to be able to handle 75+ devices each.
Must have been a short AWS outage last night. I came home and couldn’t turn my alarm off via app. Entry and Motion sensors were not in my list of On Duty Devices for HMS. Cloud events list was empty. Couldn’t control bulbs and plugs. App kept pushing “Failed to update device list (error code -1)”. I’m glad it got resolved quickly.
