miamojo See my post below yours. Right now I'm not focusing on connectivity speed - going to fast.com it starts real slow like a few Mbps for the first few seconds, then ramps up and up until somewhere between 30 - 240 Mbps, depending on where I am in the house (I get 230-240 Mbps from Ethernet). That is pretty consistent with what I've been getting even before this issue started. I plan to address the speed issue with Eero support eventually, but right now top priority for me is getting a connection that doesn't drop out...

rtlee My speeds are consistent with yours and I also have Xfinity (200 Mbps down,15 up).  I would completely agree- the speed variations are certainly tolerable for most things, but the constant drop in connections definitely isn't. I am headed now into my last few days of being able to return my system, and I'm not sure what to do. I had Netgear extenders(not the Orbi) which brought my speed down considerably(topping out at 60 if I was literally right next to an extender) but at least I stayed connected. I feel the potential of the eero and when it works smoothly, for that hour or so after a network restart, I feel like it would be a step backwards to go back to those extenders and I think I can wait it out but as I've been typing this, the connection has dropped twice while my son has been watching YouTube- that's twice in three minutes. It's really bad. I think the problem exists for the Orbi and Google WiFI and all the others, so I don't think I would try another system either until I read reports of solid connectivity with iOS. 

stevebaker good news! I am traveling and won’t be able to test again until Monday but I now have the test build loaded on my system as well.

Fingers crossed your experience is stable and I find the same next week!

travisbell Does this happen when you are actively using the phone? Or do you only notice it when you unlock it from sleep at your home?

iOS does a ton of weird stuff with the Wi-Fi radio to save battery using (from what I have found) various different timers and conditions both in and out of device sleep mode.  I have also found that the device may appear to switch to cellular via the status bar UI indicators, but in fact remains connected to the Wi-Fi network according to the network stack.

So if you are seeing LTE for a brief time and usability isn't actually impacted, then its probably just iOS doing its "thing".  I think the best way to tell is to run a ping to your router from an app on your phone and look for network dropouts to determine if the association is actually dropping, or if this is just a UI thing.  The idea here is that a transition to LTE or an association drop will result in lost packets.  You can also try pinging to your phone from another machine on your network (e.g. your Mac/PC), though be aware it is normal for the device to drop off the network and stop responding to pings if it enters sleep mode.

Keen to hear what you find!

mattv123 Both times it was connected to WiFi prior and I was in the middle of using it but I had moved in the house. It's the same time it would have dropped the signal for good on 3.3 when I suspect it was switching AP's. From that perspective nothing is different. Just in the middle using it. 

I'll continue to monitor it. I've told everyone in the house to try and pay attention too :D

pclaar Ya, that is a video of my experience. When I said earlier that WiFi came back faster, I only meant that the WiFi returned from being on LTE faster. I never actually specifically checked the time it took to have a working network connection again. You can very conveniently see that with that app. 

I'm going to grab it and walk around now.  Thanks for sharing. 

travisbell For others, here's a link to the app: https://itunes.apple.com/us/app/wi-fi-sweetspots/id855457383?mt=8

rtlee Did some testing for support today. Interestingly, my iPhone 7Plus (on iOS 11 gm), and iPad Pro REGULARLY have wifi cease functioning. On the GM though, they recover on their own (so sometimes I might not notice there was an issue unless streaming something).

My daughters iPhone 7 Plus on 10.2.1 & 10.3.3 would never COMPLETELY lose the connection, but it would get VERY slow, and then never recover to previous speeds. So if you asked her, she'd just say our internet SUCKS, because it's so slow all the time.

Also interesting to me was that MacOS doesn't SEEM to have the same issue. A few pings were dropped while walking around, but only 3-5 at a time, and then all would be good again.

Hope we can get another build of the 3.4.0 that keeps make improvements and addresses both issues my family is seeing. 

bdplatt Thanks for the detailed info! As I recently reported, I've seen much of the same problems so the beta firmware hasn't seemed to help much if any. Possibly it recovers a bit easier, but I still have several dropouts and have to resort to toggling Wifi. A few times now I have returned home to find that it connects to the Wifi but has no connection, and I have to toggle Wifi. That seems new with this firmware (coming home and not getting a good connection to start). Tho this does not happen each time I return home. As you can read about below I am nearing the point of moving on with another product, but that will be a costly switch.
