I use wifi calling often as our cell signal is not great. I am seeing regular drops on multiple android phones, where the phone will message that "wifi disconnected" Before I get on the phone with Verizon, I was curious if anyone has a similar problem. I am running a R7800 with 19.07.02 on it.
I'm currently experiencing this exact issue after upgrading to 19.07.3. Had no issues on the previous build, 19.07.2. I'm running two Linksys WRT3200ACMs linked by long network cable to cover a ~3000sqft rambler.
