iOS14 WiFi Calling crashing Airport Extreme base station

[Farsider]

Hi all,

I have an iPhone XS Max connected to a 5th generation Airport Extreme (A1408) that has served me well for years and its been working great. Where I live I get no cellular reception so I rely on WiFi calling. This has been working great for many years including on iOS13.

I updated my iPhone XS Max to iOS14 yesterday and now when I make or receive any calls using WiFi Calling, the Airport Extreme base station crashes. Its still online as my Mac connected to its ethernet ports still works but no WiFi connectivity on the 2.4Ghz or 5Ghz bands. No other devices can connect to the same base station either. Only a power cycle restores service....until I make or recieve another call.

Anyone else seeing this?

Wow that's crazy; AEBS have always been the most simple, dependable things on Earth, from my experience!

Validating - we're experiencing the exact same behavior at home as well. Had to turn off wifi calling entirely on both iPhone XS Max devices. I've been kicked off of multiple video calls in the past 2 days until we figured out the correlation.

EDIT: To clarify, I'd be on a Teams video call for work and my husband makes a phone call on his XS Max, and I get disconnected. Seems to be making a phone call from cell phone with wifi calling turned on that's causing it. We can reproduce consistently now. Wondering about buying a new wifi access point now.

I x-posted the same in the networking section and others are coming forward with similar issues.

Update. I raised this with Apple Support today. They are keen to hear more. I have a telephone can scheduled tomorrow with a representative from their Senior Engineering team to discuss further.

Apple Support have escalated to Engineering for comment.

Conversation continued here.

So glad I saw this thread. We have an Airport Extreme in our cabin. If I am on WiFi and take a WiFi call it drops everyone from the network.

Had to reactivate AT&T’s router WiFi as a work around.

I’d get an Orbi like I have at home but such a waste as we are on super slow DSL here.

iOS14.0.1 has resolved the issue.

Oh yes maybe yes. This started happening to me a few days ago. My Extreme's SSID would disappear and the Green "everything is wonderful" LED would remain green even if I disconnected the upstream ethernet cable. During this "No SSID, all green" state, DHCP would not serve my device a new IP address when I plugged a device into one of the Ethernet ports.

Being very forward-thinking, I swapped in my spare Airport Extreme (another known-good A1408). I was shocked to see the same behavior. Green LED, but crashed after a short while.

We definitely use WiFi calling, so this is a strong possibility. Thanks for the info. More soon if I learn more.
