AT&T 4G LTE Problems.

[karadactyl]

Over the last couple months I have noticed my 4G LTE not coming in as well as it used to. Most of the time I only get 2 or 3 bars, and hardly anything ever loads. I set a wap.cingular APN to avoid connecting to LTE, and the regular ol' 4G works great, but it randomly disconnects ALL THE TIME. I can usually get 3 to 4 bars of regular 4G, and it is so much faster than the LTE it's not even funny, but it disconnects at random every few minutes. If I wait patiently it will eventually reconnect, but sometimes I have to switch back and forth between APNs or restart my phone to get it to work again. Are there any APN settings that I could use to avoid this, or any other solutions at all? Also, any advice about the LTE?
