As of about 2 months ago, the signal around my house, about 50 ft in any direction, is almost always non-existent. My signal strength when standing outside shows -116dBm - basically nothing. Occasionally during the day the signal suddenly boosts to full strength for a few minutes, only to drop back down.
Is this a cell tower issue? cell blocker somewhere? Prior to 2 months ago, we had full signal 100% of the time
