Wifi calling issues with Samsung Galaxy S21 and Verizon

[bdmoore2]

Hello,

I have a Samsung Galaxy S21 on Verizon that is having issues with WiFi calling only on my home network.

All WiFi data and apps work properly on my home network. I have ATT fiber with a typical speed of 700Mbps. I have Wifi calling enabled and have verified with Verizon that it is enabled on their network. I've asked them to reset my network settings in their system to be sure. However, WiFi calling works perfectly fine on other networks. I verify this by turning on airplane mode and making calls with only wifi connected.

I am able to get WiFi calling to work briefly at home by switching the network from automatic to manual and select Verizon. I then reboot my phone. WiFi calling works for a call or two (~15min), then stops working... 

So it seems to not be an issue with my phone or verizon... so either the nest network or ATT fiber. 

Any settings in the nest router that could interfere?

I have SW version 14150.43.81 ( saw another thread that recommended updating to 14150.43.80, but more recent so I assume that isn't the issue)

Thanks!

I spoke with people at vzw and they told me It will be fixed in the next security patch

Hey there,

Thanks Meir for the information.

Sorry for the delayed response, bdmoore2.
 

To confirm, is your Wifi calling working with other networks like a mobile hotspot or other wifi networks apart from your Google Nest Wifi? Are you using a modem/router combo provided by AT&T? If so, what is your network structure (modem/router > Google Nest Wifi router > Google Nest Wifi points)?

Give these steps a whirl:

1. Restart your network by unplugging the power from your Google Nest Wifi devices for 10-20 seconds.
2. Change the network name and password of your Google Nest Wifi network name and password, then have your Samsung Galaxy S21 connect to the new network and try Wifi calling.
3. If the issue persists, try contacting Verizon support to confirm if the security patch will help fix the concern.

Best,

Mel

Thanks much for the suggestions.

I was behind on a few updates on my phone and installing them greatly improved wifi calling. 

If the issue comes back, I'll try the network tricks you laid out.

Hey bdmoore2,

I just wanted to check back in once more to see if everything stayed stable and if things are still looking good for you. Let me know if you've had any issues.
