More than likely, your satellite internet is chugging along slower than usual if you've gone over your data cap for the month. But problems with your satellite dish, cables, or modem could also be to blame. That said, satellite internet isn't known as the speediest internet connection on the block. Even Viasat's "unlimited" data plans come with a data cap. You'll still get to browse the web, but your speeds will slow down to 5 or even 1 Mbps. That is slow. We cover Viasat's data caps and slowed speeds in our guide to Viasat data. If you're still under your data cap for the month, you might want to update your modem's and router's firmware, then take a look outside at your cables and satellite dish. We'll walk you through what to look for in our tips for speeding up your satellite internet.
