Charter internet sucks!!!

[cbaer5]

hey guys so long story short after 7 months of having really slow upload speeds a charter tech tells me why. They have to replace a overhead line that crosses a train track that is in use 24 hours a day and to do so they need a permit from the city. So I'm beginning to think this might take a long time so has anyone used or uses one of those 4g cell tower internet companies they are calming 18mbgs at my house. Is this accurate? worth the money? any problems you guys know of? thanks.
