Bandwidth throttling occurs when someone intentionally slows down your internet speed. Anyone with administrative privileges over the network, which reduces the available bandwidth, is engaging in bandwidth throttling. Regarding censorship and net neutrality, the perpetrator is typically the internet service provider and/or mobile carrier. But throttling is common on public networks at hotels, cafes, airports, and restaurants. In this article, we’ll talk you through why your internet might be being throttled and teach you how to bypass the issue by using a VPN.
Short for a virtual private network, a VPN encrypts a device’s internet traffic and routes it through a server in a location of the user’s choosing. VPNs also provide privacy to everything you do online, preventing your ISP and governments from snooping on your activity. They secure wifi networks against hackers, you can use them to unblock geographically-restricted content, and they can uncensor the web in environments where specific content is blocked, such as corporate office buildings and schools.
Why your internet might be being throttled
Reasons for throttling your bandwidth can vary from one ISP to another, but here are a few common examples:
- The ISP might throttle bandwidth to certain websites, apps, or services in order to discourage their use and encourage the adoption of alternative services that benefit the ISP and its affiliates
- The ISP might be required to throttle bandwidth to content and services deemed illegal, inappropriate, offensive, or sensitive by the government
- The user exceeded their monthly data cap, triggering bandwidth throttling as a penalty and to prevent abuse
- Your ISP plan has a bandwidth limit, either for all traffic, specific types of traffic, or specific websites and services
Whatever the reason behind ISP throttling, it can significantly impact your internet experience. It can affect streaming speeds, download times, and the overall performance of specific applications. You may also experience higher ping times when playing online games or using voice-over-IP services.
The first two cases can be remedied with a VPN. The VPN’s encryption prevents your ISP and anyone else on the network from seeing the contents of your web traffic while the server disguises that traffic’s destination. VPNs also mask the type of internet traffic, so there’s no way for your ISP to differentiate between VPN traffic from a web browser or a BitTorrent manager, for example.
If yours is the third or fourth case, not much can be done. Save for switching providers; your ISP will always know how much total data and bandwidth you consume. However, many VPNs can compress data before sending it to save bandwidth, which could lower your total data consumption. Some can block ads and other unwanted traffic, saving your precious kilobytes.
How to prevent bandwidth throttling with a VPN
Getting set up with a VPN is much simpler than you might think. Just follow our simple step-by-step guide below.
Here’s how to bypass internet throttling with a VPN:
- Start by signing up and purchasing a subscription from a reputable VPN provider. We recommend NordVPN. It uses top-notch encryption and perfect forward secrecy to keep your data safe. It stores no identifying usage logs or metadata. All traffic, including DNS requests that typically go through your ISP, is routed through the company’s global network of servers. Finally, it’s fast, so you won’t change one form of bandwidth throttling for another. Apps are available for Windows, macOS, iOS, Android, Linux, and certain wifi routers.
- Once you’re signed up for a VPN, download the client software to your device.
- With the app installed and running, you can either click the Connect button to automatically choose and connect to a nearby server or click the option to manually select a location.
- Wait a few seconds for the connection to establish. You’ll receive a notification upon success.
And that’s it! All your internet traffic will now be encrypted and routed through the VPN server. This should allow you to bypass most types of bandwidth throttling, as laid out above. If your ISP was throttling bandwidth for torrents, they should download faster. If it was throttling video, it should now stream smoother.

How do I know if I’m being throttled?
A simple speed test should be enough to ascertain whether your bandwidth is being throttled. Head over to speedtest.net and run the test. If you are getting speeds significantly below what your subscription promises, even at off-peak hours–then there’s a good chance you’re being throttled.
If you think that a specific website or service is being throttled, this is more difficult to prove. You’ll need to monitor your network while using said website or service to see what sort of speeds you’re getting. This can be done on your device or wifi router if they have such a capability. Windows 10, for example, allows you to monitor network bandwidth under the Performance tab of the Task Manager.
When testing, make sure no other devices in your home are eating up bandwidth. Check to see if you’re running any automatic backups, downloading software updates, or have contracted malware that’s using your internet.
Is bandwidth throttling legal?
This depends on where you live. Countries with strict net neutrality laws ban the prioritization of traffic. ISPs in these countries are required to treat all traffic equally and cannot intentionally slow down or speed up specific websites, apps, or services.
Bandwidth throttling is generally legal so long as the throttle applies to all traffic and not specific websites and services.
The FCC’s Open Internet Order requires ISPs in the United States to treat all internet traffic roughly the same way. They cannot discriminate by application or service, device, or content. ISPs are categorized under the same rules as utilities when providing service.
US net neutrality laws are currently under threat, however. The FCC, under the Trump administration, aimed to dismantle the Open Internet Order and instead give the FTC regulatory power over these issues. Critics argue that the FTC will not be able to adequately protect consumers, however, and say the current law should be kept in place.
ISPs want to remove net neutrality laws to provide faster access to products and services that benefit them, such as affiliated video-on-demand sites, while slowing down competing sites. Verizon was caught testing this throttling as recently as July 2017. They could also charge other companies for fast-lane access on their networks.

As part of the EU’s Digital Single Market, ISPs cannot block, throttle, or discriminate against online content, applications, and services. Due to Brexit, however, the future of net neutrality in the UK is uncertain.
Prior to the EU law taking effect in 2015, the UK used a voluntary system to keep net neutrality in place. But once the UK leaves the Union, the current law could be scrapped. And since the majority party doesn’t have the greatest record of protecting citizens’ digital rights (see: the snooper’s charter), there’s a possibility that bandwidth throttling could be on the UK’s horizon.

Canadian ISPs are known to throttle the bandwidth of certain protocols. These protocols are detected using deep packet inspection, which identifies the type of traffic traveling through its network. This can be used to reduce the speed of things like peer-to-peer filesharing, which use up large amounts of data and bandwidth. This is sometimes implemented during peak usage hours.
Canadian ISP Rogers has been known to degrade the speeds of all encrypted traffic, which would include VPN traffic.

Australian ISPs are known to engage in zero-rating practices but not so much bandwidth throttling. Due to a more competitive market, it’s not in their best interest to prioritize traffic.
However, the country has not enshrined any actual laws or regulations that prevent bandwidth throttling.

What about zero-rating?
Zero rating is similar to bandwidth throttling but, unfortunately, cannot be fixed with a VPN. Zero-rating occurs when the ISP doesn’t count traffic to certain websites or services against the user’s data cap.
For example, if AT&T allowed customers to stream videos from HBO Go without expending their monthly data allotment, this would be zero-rating.
Laws and regulations are less clear about zero-rating schemes, but net neutrality proponents are against it. They say it creates an unfair advantage for established players and prevents startups and small businesses from gaining a foothold, thus stifling innovation.
Bandwidth throttling FAQs
Can You Use a Free VPN to Bypass ISP Throttling?
You could, in theory, use a free VPN to bypass bandwidth throttling, but we wouldn't recommend it. Free VPNs often lack the level of encryption and security features a premium provider offers, such as DNS leak protection and a kill switch. For this reason, there's no certainty that your online activities are consistently sent via a secure VPN tunnel. If not, your ISP will have traffic visibility, allowing it to throttle your bandwidth.
Does bandwidth throttling affect mobile devices too?
Bandwidth throttling can affect any device connected to the internet, whether using mobile data or if you're connected via wifi. No device is safe from throttling unless you use one of the above methods.
I am a current customer of Mediacom. I pay for a 100mbps. I get about 120 Mbps speeds on my computer when running speed tests from various test sites. However I’m getting drastically reduced speeds on other home devices.(Smart TV 3.5 Mbps and Roku 70 Mbps) I have everything hardwired to my personal modem via ether net cables and I’m not running numerous devices at once nor am I using Wifi for anything. When I initially purchased the Smart tv a couple years ago it was running at about 20 to 30 Mbps out of the box. The tv is a Vizio and has a built in Network speed test function. It worked fine for about 6 months then suddenly overnight it dropped down to 3.5 and has stayed there since. The apps are extremely slow to load and the TV seems to have a mind of it’s own. At times the volume turns up and down by itself and my youtube browsing history clears itself without my consent. I took the TV to a couple friends homes and tried it with a different ISP, Cox and Centurylink and the speeds came back up to what they were receiving from their ISP. I have checked the specs for the NIC in the devices and they both will operate at up to 100 Mbps. There is nothing mechanically wrong with either device. I recently had my ISP do a speed increase from 60 to 100 Mbps for an extra $10 per month charge. The speed increased drastically on my computer but stayed the same on the other devices. I had a bandwidth cap of 400 GB at 60 Mbps download plan but have never even exceeded 200. After the speed increase I’m now allowed 1000 GB so that’s not the problem. My ISP has been out numerous times and claim they are not capable of targeting specific devices but something is definitely wrong. My signal acts as though it is being rerouted to an alternate server somewhere and I can’t figure out what the hell is going on.
