Troubleshooting slow internet speeds



Here's what to do if your internet service seems to be running slowly

Understanding How Your Plan Can Impact Speeds

Data Capped Plans

The most common reason subscribers on a data capped plan experience slow speeds is the monthly data allowance has been exceeded. When that happens, your access won't be blocked, but speeds will be restricted and significantly slower.  If you're in restriction, you should already know it; we send restriction alerts that pop up on your browser. We also send out email notifications when you’re at 70% (for non-Liberty plans) and 100% of your data allowance. Log into MyViasat to see how much data you have used and how much is available for the current billing period. 

If you've reached your data allowance limit on a capped plan, here are a few options:
·      Wait until your new billing period begins and your data allowance resets to zero.
·      Shift your online activity to our un-metered Free Zone hours if your plan has one
·      Purchase additional data via the Buy More program.
·      If it's available, upgrade to a new plan with a higher limit. To check for new plans go to

For Liberty 12/25/50 customers only: You have an Early Morning Free Zone from 3 to 6 a.m.

For Evolution customers: A data allowance restriction won't affect the speed of your web and email access, but will restrict the ability to download and upload files, stream media, and all other activities. During the Early Bird Free Zone (3-8 a.m.), all activities are un-metered.

Unlimited Plans

The most common reason subscribers on Unlimited plans experience slow speeds is because they have reached the data threshold for the service plan and the network is congested.

On an unlimited data service plan, there are no limits to how much data you can use during your monthly measurement period.  Depending on the specific unlimited data service plan available at your location, after you exceed the data usage threshold for your service plan listed below we may prioritize your data behind other customers during network congestion, which will result in slower speeds.

  • Bronze 12 - after 35 or 40 GB of data usage 

  • Bronze 25 - after 35 GB of data usage

  • Silver 12 - after 45 or 60 GB of data usage 

  • Gold 12 - after 65 or 100 GB of data usage 

  • Silver 25 - after 60 or 100 GB of data usage

  • Gold 50 - after 100 GB of data usage

  • Platinum 100 - after 150 GB of data usage  

When the network is not congested, nothing will happen to your service speeds even if you have used over your monthly data usage threshold.

The data usage thresholds for each unlimited data plan are defined in the Unlimited Data Policy.

How slow is too slow?                                                     

Speed may vary slightly depending on overall network demand. For instance, service may sometimes be faster during the day than the busier evening hours. Here are some tips to help find out why you may be getting slow speeds and how to resolve these issues:

1. Find out what speeds you're getting  

We recommend checking your speeds to see if they are in line with the plan you are on. 
Visit to test your speeds. 

Please be aware that many other speed-test sites may report inaccurately over a satellite network. 

2. Reset the modem

The simplest fix often is to reset your modem: Unplug your modem from the electrical outlet (and router if you have one) and plug them back in. 
Read our router info page for more on how to properly reset your network. 

3. Test the web page

Try loading several different pages. If most are fast, but a few are slow, the issue is probably with those sites not your Viasat service. Try again in a few hours and see if there's a difference.
If one site is always slow or never loads correctly, please report to customer care so they can refer it to our engineering team. We can determine if our web acceleration technologies have trouble with that site and fix the issue if one is found.

4. Clear out your browser

Keeping lots of history and temporary files in a browser can slow down the browser and make your Internet connection seem slow. Clear your browser cache and temporary files. Keeping your browser up to date will ensure it loads the bug fixes and optimizations needed to keep your web surfing smooth. Your browser’s Help section will have information on how to update it or clear the cache and history.

5. Do a weather check

Heavy storm activity can affect the signal at your home dish as well as at our ground stations. These disruptions are more typically a short-lived outage.

6. Check for simultaneous household access

If several people in your household are using your Viasat service at once over a wireless network, each may experience slower speeds. This is especially true if at least one of the users is streaming video. When testing speed or verifying slowness, make sure no one else is using the service. If everyone else stops using the service and the speed returns to normal, it may not be an issue with your service but with your router or another device on the network.

7. Check for open Wi-Fi access

If you don't have a password on your wireless access point, someone might be using your internet without your knowledge. Set a password on your wireless router to help prevent any unauthorized use. If you have a password set and suspect too many people know it, considering changing it.

8. Run a virus scan 

Ensure your antivirus is up to date along with your operating system updates. Run a virus scan to make sure you don’t have any viruses, malware, or botnet software installed on your computer.
Other types of software that can slow down your computer and use your internet service include weather widgets, browser toolbars and stock quote widgets among many others.

9. Give your hardware and health check or update 

The internet today isn't the same as it was 5 or 10 years ago. Websites require much more power from computers to run smoothly and load quickly. A computer with at least a dual core CPU and 4 GB of RAM (memory) will provide enough power to run internet applications well. So what appears to be a low internet connection could actually be an outdated, less-capable computer.
Try using your Viasat Internet service with a newer, more powerful computer, tablet, or smart phone. If other devices perform well while your computer is slow to load web sites, the issue may be your computer — or even malware of some sort running on your computer.
Before you replace it, consider having someone check it for problems.

10. Consider Router Issues

A router can have a significant effect on the performance of your service. Since all devices in your home connect through the router, it can be the bottleneck that hampers your service - especially if you have more than one user on your network simultaneously. To find out, connect your computer directly to your Wi-Fi modem, bypassing your router. If speeds increase and slow speed issues go away, your router could be faulty or misconfigured.

If your router has a built-in wireless access point to provide Wi-Fi, the issue could be interference or distance from the router. Wi-Fi signals, microwaves, televisions, portable/cordless phones, electrical wires, other electronic devices and even walls can create interference. Try to set up your router away from other devices, and in the center of your home or work area. If you're several rooms away from the router, your Wi-Fi will be significantly slower than if you're in the same room or within a clear line of sight.

To determine if interference or proximity is an issue, place your router away from other devices and run a speed test while you're in the same room. If the issue goes away, there may be something interfering with your Wi-Fi signal.
