I have my nexus 5 on Viareo wireless and the 3G/4G connection has been working fine, until today. I am currently a block from the tower and whenever i try using my data connection if i download more than a few mb it drops the signal and then reconnects. What i mean by that is when doing a speed test or downloading an app after a few seconds the signal bars go blank for about half a second then fills back up again and the download stops. I can send and receive texts and calls fine, but the data acts like i only get a few mb and then it resets the connection. Does anyone know how to fix this?
