My mother and I have been having issues with our phones not sending texts and dropped phone calls due to both basic phones being connected to a neighbor's network extender. I would talk to the neighbor except for the fact that, after researching this, turning it to private does nothing. It is a managed mode, not a completely restricted mode, therefore outside lines are still able to connect to it. It even says prioritized in the setting. Is there any other possible way to fix this issue?
