About a week ago I bought a Google WiFi 3-pack to replace my Apple Airport hub (most recent gen). The Airport was working OK, but in a couple spots of my house, the 5GHz signal strength wasn't great. Also, I liked the fact that the Google WiFI app for my iPhone would let me monitor usage, more easily allow guests access to our network, etc. I finally hooked up the Google WiFi hubs 2 days ago. During day 1 I hit an issue with WiFi Calling (side note: my house has poor cellular coverage for all carriers - I'm with AT&T - I get about one bar of AT&T coverage inside my house). Because WiFi Calling has never been great for me in terms of handing off the connection (my iPhones will too often want to latch onto that 1-bar of cell signal instead of using WiFi Calling), so I've started putting my iPhone into Airplane mode at home, to force it to use WiFi Calling. Well, in Airplane mode I tried making a call on day 1 and got an error message on my iPhone telling me that I needed to either disable Airplane mode or connect to WiFi, but I was connected to WiFi just fine, and confirmed it by pulling up some websites in Safari. It turns out that there's a longstanding known issue with Google WiFi and WiFi Calling. One supposed fix/workaround was to change the DNS settings. I tried that and it seemed to work day 1, but then day 2 I had the same issue again. The other workaround that several people claim works is to go into the Google WiFi app and tell it to give your iPhone priority (whatever the wording is). I didn't even bother trying that, because that's not an acceptable workaround, as I may have other people in the house who also need to use WiFi Calling. Sorry for all of that extra background, because that has nothing to do with the Apple Watch. So on day 2 I ran into another issue which I assumed was due to Google WiFi, but maybe it was just a coincidence and was caused by something else, so I figured I'd post about it here...I couldn't unlock my Apple Watch with my iPhone and I couldn't unlock my MacBook with my (manually unlocked) Apple Watch. If the problem isn't Google WiFi, the other theory is that I recently bought an iPhone SE as an experiment to see if I could be happy using it instead of the iPhone XS I recently upgraded to, and I just so happened to re-pair my Apple Watch with the iPhone SE on day 1, so I was introducing multiple variables into the mix. So it's possible that by switching from one iPhone to another, I caused something some confusion. But once I hit this issue and couldn't seem to resolve it, I decided to unplug all of my Google WiFi hubs and switch back to the Apple Airport. After doing that, I was able to unlock my Apple Watch with my iPhone and unlock my MacBook with my Apple Watch. So it sure seems like the culprit was Google WiFi. Has anyone else run into this and, if so, are you aware of a fix? I didn't see anything in the Google support forums about this issue.
