About 2 weeks ago I lost the ability to place calls on Wifi on my home network. It works on other wifi networks. The RW app diagnostic tool says I have an SIP Connection Failure.
RW has been very helpful by providing a good list of items to troubleshoot (nothing worked); my ISP says I need to upgrade my service ( though I have great speed, etc.).
Wifi works on the phone for data, etc., and all else is fine.
I’ve reset the router (Apple Airport Express), and factory reset my phone. The modem is about 9 years old; the router is about 8 years old.
Do I simply need new hardware? Any other suggestions?
Phone is a Moto E (4th gen). Same issue on a Moto G6 in the house.
