Who I have the same questioned this topic

We used to have decent upload and download speeds on 4G. Just last month, we had 18 down and 6 up for example. Signal strength about 3 bars. But then it suddenly dropped to under 2mbps each, same signal strength.

We added an antennae on the roof and have tried pointing it at the different towers in our rural area. We can get 3 bars signal strength but speed tests are consistently .5 download and .2 upload. This is unusable really.

We've driven around to other towns and have excellent speeds. 

Our zip code is 27562. Yes, it's rural, but it should still work. Our area has no high speed internet option....only DSL from CenturyLink and they're actually turning down new accounts even for that. Does the cell tower need to be upgraded? How to request a review of the tower? We're desperate for a solution.
