That's what my friend said should be done to fix his slow wifi. It doesn't affect his phone because he has regular service for that, but now that he's got roku tv, it could be a problem. I often use wifi for my phone there. Does increasing bandwidth really help? There's only one company providing wifi in the back of beyond, and he had to go all the way over to the highway to get it done. By the way, internet service was practically nonexistent the other day, but it was cured by nightfall.
