mattv123 Appreciate your insight and contribution to this topic. I'd go a step further and suggest that this could sink eero as a company if they don't address this problem head on, and quickly. Here's hoping that eero realizes that and pours every available resource into solving this before this becomes common knowledge outside of this forum and reddit.

With iOS11 in GM, it really doesn't matter if this is an iOS bug anymore. The bottom line is that eero and Apple products have compatibility issues, and eero is the company who will lose this battle.

pclaar I don’t know if it’ll sink them as a company but I do know that I’m gonna return mine.  I bought both gen1 and gen2 and don’t have time to sit around and send them bug reports and soft reset and switch all my devices to help them.  I barely have enough time to debug my own crappy code.  Maybe I should be happy, they are saving me 500 bucks. 

polar  I really hope eero sort out the iPhone issues because they are the best alternative to the Airport Extreme. This is the only reason that I have put off replacing my Airport Network. I am confident they will sort it out as this will have a negative effect on them as a company.

CoolTechGuy I've had Wifi calling disabled for well over a year now, yet I have all the same issues you do. My guess is that by disabling it you temporarily reset things and it is clear for now but considering I have the issue with wifi calling off I don't think this is going to fix it for you unfortunately. Please keep us posted either way. 

rtlee Well the resetting of AT&T WiFi calling feature didn't help.  And since I last tried that last week, I've updated my iPhone 7 (and all other iOS devices) to the iOS 11 public version (GA) last Tuesday and seems to have only gotten worse.  So bad in fact that I went back to exclusively using my UAP-AC-Pro (two of them).  All was good with those access points for about a day and then my password would be lost on all iOS devices.  It would say enter password and after entering it correctly it said wrong password.  I disconnected the UAP-AC-Pro access points and put back in place my three eero pro units (2nd gen).  Then I still got the enter password on my iPhone even though the SSID and password was still the same, same as the UAP.  Then it occurred to me, maybe this is all only iOS related and need to reset my Network Settings on my iPhone 7.  So I went to Settings | General | Reset and then did "Reset Network Settings".  I did this process this morning, so here is hoping the issue will go away with a network reset on the iPhone.  I'll post my results after a few days. 

CoolTechGuy Thanks for those details. In my case doing a Reset Network Settings did not help at all.

rtlee Ends up that doing the iPhone 7 Network Reset did not help.  I did want to mention that I use FiOS and so I have to use that modem.  I've been running eero with network dhcp & nat set to 'automatic' but switched to bridge mode.  Bridge mode is how I originally had eero set up and the disconnect didn't happen as often, but still did occasionally.  I'll report back in a day or two how this setup works.  I read where someone in this thread had deleted their eero network and re-created it.  It also had helped them some and I may do that too if bridge mode doesn't help.

Switching eero network to Bridge Mode did not help at all.  I may take down my three eero pro units and go back to my two Unify UAP-AC-Pro access points.  I had an issue with UAP but I think it was a setting I had tweaked needs un-done.  They had always been stable and reliable.  If they aren't, I'm considering Amplify HD or Orbi. 

travisbell Can I volunteer to run this test build as well?

travisbell Good news! I am awaiting the test build too and will report back once I’ve tried it out.

Thank you, eero support, for working on this frustrating issue. Fingers crossed!

afx114 It's up to Eero who they deploy this build to. I would guess that Eero grabbed a random sample of users from those who have reported the issue. The more people running some tests builds the better, especially given how hard this one was to reproduce according to Jeff.

miamojo That sounds pretty bad, glad they have a possible fix. I only seem to need to do it if I move around dramatically at home, definitely not as bad as every few minutes.
