I have an SLS-BU103 installed. Worked great on my Samsung S10+ and wife's Note 9 for 6 months. About a month ago, calls started to drop after 5 minutes. Verizon customer service was not able to help. I have rebooted, factory reset the extender and changed settings on phone. Wifi calling is disabled. Nothing worked. Internet speed is 500Mb down, 20Mb up. No issues with Internet access dropping.
I am in zip code 95610.
Any help would be appreciated.
