It is March 2022 and I can report that I am experiencing an issue very similar to that originally reported by oviano . Two weeks ago we switched to an eero pro 6 mesh network (GW and 2 nodes) after our community went into ISP contract with Frontier Communications. Shortly after, we started experiencing temporary disconnects on various wireless devices. We have some security cameras going offline for hours at a time; one of them los wifi for almost 2 days. We are also experiencing disconnects on smart plugs, and on most apple devices (Apple TV, tablets, phones, laptops). Prior to eero and Frontier, we had an Arris Surfboard router which was provided by our previous ISP. For wireless connectivity we were using an Apple AirPort Extreme configured in bridge mode. 

I’ve been taking note of the problem, but I did not have the opportunity to look into it until yesterday. Following basic troubleshooting steps recommended by eero on their customer help page, I followed their disconnect, restart, soft reset -suggested sequence with no change in outcome. Also did reset of network settings and hard reset on many of the devices; no help. I ended up doing a hard reset on all 3 eero nodes, effectively deleting the network and doing a factory reset on the nodes. After setting up the network again, all problems went away….until this morning. 

The first thing I noticed was that my iPhone was not connected to wifi (the eero GW seating 4 feet away).  Tried power cycle of the phone and nothing. Going into wifi settings showed that the phone was connected to wi-fi but the device did not have an IPv4 address assigned. Walked up to one of my kids and her phone showed a valid IPv4 address assigned, but also showed that same IP address as the router address.

This was first thing in the morning which is always busy at home, so I had to put this aside for while. About 90 minutes later, the phone was connected to the network. A quick check with a speed test app showed good network performance. I am working from home today, and I have not seen any connectivity issues with  my devices, the security cameras or other devices. I’ll have to check devices for other family members when they get home, but I am not feeling very confident right now. The eero pro 6 mesh system has been having this problem since it was installed. As of today, the nodes are running eeroOS v6.9.0-706 (installed last night through automatic download).

The eero app is not offering me many configuration options either (I miss the Arris router in this regard). I’ll turn off IPv6, and see if that has any effect.
