CAX 80 / WIFI calling issues
Just recently upgraded from the Netgear C6220 to the CAX80. I noticed that the WIFI calling feature on my Samsung Note 10 Plus is no longer working. I cannot send or receive calls/texts over WIFI...
- Solved:
After 7 months of painful troubleshooting we have finally found the fix to wifi calling.
It seems the culprit was "ipsec alg". The service is not found on the official firmware and therefore cannot be disabled.
For everyone with the issue:
You must contact netgear support and explain the wifi calling issues and that you'd like to try the beta firmware with the ipsec alg feature. Currently they do not have plans to release it publicly. Not sure why.
Februrary Update:
I have finally gotten the issue pushed up to Netgear's engineering team. They are now aware of the issue and working on a fix. It has taken awhile to get this issue recognized as a widespread problem and not an isolated incident. A big part of this was trying to get Netgear to realize that the problem was the router and not a myriad of other things (phones, carriers, internet connectivity, etc...). Whatever it is, it seems to be affecting Samsung devices in particular.
Hopefully we will have the issue fixed soon and a new firmware update in the not too distant future.
Happy to hear that. Now, we wait. We installed the NETGEAR CAX80 just over a week ago, on the Xfinity network. I have a Samsung Galaxy S9+, and my wife has an iPhone 11. Hers still works with Wi-Fi calling; mine does not. We're in an area with sketchy mobile coverage, so have relied on Wi-Fi calling, inside our home.
