My wife and I have been experiencing issues with our data connection at home. We will see our connection cycle from 3G to 4G to 1X without moving. As it cycles, we will see a delay where we basically have no connection at all, as it tries to switch. This appears to also cause an increased battery drain. We use a Samsung Galaxy S4 and Samsung Galaxy S4 Mini. We are in the 38135 area code. I do not see these problems outside of our home neighborhood. We have had this issue both indoors and outdoors. Any suggestions?
