I've spent around 6 weeks working full time from the fort, I wouldn't rely on the wifi at all, go with your own cellular hot spot, I personally use Verizon att and t mobile since I rely on it so much and generally speaking I found t mobile to provide the highest floor for its service, meaning that it's peak isn't the best but it's lows are generally acceptable, I suspect that when crowded att and vzw are congested and this is when t mobile starts out performing them.
