We recently upgraded our phones from Iphone 8 to Iphone 12 and discovered we now have poor signal quality at our house since they have not upgraded the nearby towers. Verizon sent us a Network extender 4G LTE, which we installed and plugged into our WOWWay internet modem and it initialized just fine and seemed to work right off the bat. But, we started noticing that we will receive calls were we can hear people, but they can't hear us and it would take up to three call backs before we could finally hear them and they heard us. This is occurring all the time now and we don't know what is going on or what to do to fix it.
Anyone else having the same issues?
