Fantastic! I am happy to read that you are now able to make/receive calls over Wi-Fi. Thank you for posting the changes your Netgear Router. Let us know if you have any other questions or concerns.
interesting. Those are all VPN protocols. Any clue why you decided to enable them? L2TP is regarded as a weak VPN proto. Doesn't seem to be related to your phone making an outgoing connection to VZW for wifi calling.
I have a V60 ThinQ 5G UW that originally came with Android 9 (I think) and recently went to v11. Ever since the v11, I've noticed that when receiving calls, the audio is broken and intermittent, then I have the callers call my home phone, which is over Vonage, and the audio is much better/normal. I can't admin. the Vonage device, but I do have a wireless router and understand many of the settings. From what I'm seeing here, you need to enable the VPN in order to do wireless calling? That seems odd, but it appears the only way to access the L2TP and IPSEC settings and enable them. I'm going to try and turn OFF wireless calling and see if that improves anything. I already have a VPN for my PC and not sure I'd want to be running one on my PC that would also go through the router VPN (I have an ASUS wireless router/switch) and my ASUS router is a RT-AC66R. Also, I live outside the "city" proper, but I do have fairly decent mobile coverage, and the newer phone has helped with that I think.
