Who I have the same questioned this topic

My entire family has problems with voice calls dropping in our house when we are connected to our home wifi network. If we turn off wifi, we have no problems with voice call reception or dropped calls. We have various models of iPhone and have never had reception problems in our house before, and I don't have any problem with voice calls when connected to my work wifi. About 5 months ago, I changed to a Linksys WRT1900ACS wireless router. I believe that the problem started when I installed the new router.

We are not using "WiFi Calling" or "HD Voice".

Has anybody else experienced similar behavior where being connected to a particular wifi network or router caused interference with voice calls?

Thanks in advance for any assistance.
