I have a Huawei 4G router Litecat6 B612 (whatever that means). Anyway my internet speed has dropped from 10 to 15 D/L speeds to 0.5 to 2! It is the same whether I test a hard wired PC or a cell phone. Could the weather be an issue? It's -31C right now (-40with windchill).
I tried unplugging the modem and that did nothing. Any suggestions? Anyway to give this speed a boost?
