Why is my connection speed slower?

· ·

The encryption provided by a VPN connection almost always results in slower connection speed. In some cases you may have noticed that your computer or tablet was working faster when running a VPN client application or program, that is because a computer has a processor that is normally about 4-6x times as strong as a the processor on a router, and that is for managing a single VPN connection. A router has a smaller processor and is managing an entire network of devices. Encrypting an entire network does take considerable processing power.

Speed test results while connected to VPN are never going to be accurate. A speed test measures the rate at which a data packet travels from one server to another, however when you are connecting to VPN the data packets travel to an extra server where they are encrypted and then sent back into the route. We strongly recommend disabling the FlashRouter’s VPN connection when testing speeds to make sure there isn’t and issue with the router.

Connection Types

Ethernet: Wired ethernet connections will almost always be the most stable and reliable connection. To speed up your internet connection, use an ethernet cable to wire your devices to the FlashRouter.

Wireless (5.0GHz): The 5.0GHz WiFi frequency has less range than the standard 2.4GHz WiFi, but also transmits your internet connection at a significantly faster speed. If you were previously using the 2.4GHz network and experiencing slow speeds please connect to the 5GHz wireless network which should improve your speed.

Connect to the closest VPN server

Our supported VPN providers offer many servers in different countries and regions. If a server has slower connection speed we recommend connecting to the server closest to your actual location.

The process for changing servers is detailed in your provider’s setup instructions.

DD-WRT Manual VPN Configuration

Select a UDP server

UDP servers do not authenticate every data packets the way TCP servers do which results in faster connection speeds.

Contact your VPN provider for a server recommendation that should provide the fastest speeds for you.

  2. Visit ExpressVPN’s IP Check to verify your new IP address and virtual location.

In some cases you may notice that the location is not showing the same location as the server you have input in your router settings; this is because geo tracking tools are often tricked by VPN connections. As long as you see an IP address that is not the same as your normal Internet IP address then you are indeed connected to ExpressVPN.

How to change the ExpressVPN server

  1. Download a new .ovpn file location as detailed above.
  2. In the ExpressVPN Group on the OpenVPN Client area click Upload Configuration File and select the new .ovpn file.

What is a DNS leak and how can I prevent a DNS leak in my router?

· ·

What is a DNS leak?

A DNS Leak is an instance where your ISP receives DNS requests despite being connected to a VPN tunnel.

How do I check if my DNS is leaking?

  1. Perform the extended test on DNSLeakTest.com. Be sure to do so on multiple web browsers for best accuracy.
  2. Here you should only find one server and your ISP should not be listed as your actual ISP.
  3. If your actual ISP is not listed there is no DNS leak.

How can I prevent a DNS leak in DD-WRT?

Check your device's browser settings

Updates to web browsers have added DNS settings capabilities, while this often makes your browsing experience more secure it can also effect the results of a DNS leak test. You can go into your browser’s settings and search for “DNS” and disable the DNS of the browser for more accurate DNS leak test results.

A simple web search for “DNS settings [browser name]” should return helpful information for finding the setting in your browser.

Adjust DD-WRT settings

1. On the Setup > Basic Setup page of the DD-WRT settings check the Ignore WAN DNS box.

This setting may not appear in older DD-WRT firmware builds. If it is not appearing for you, upgrade your DD-WRT firmware.

DD-WRT Check Ignore WAN DNS

2. Lower on the same page check the Forced DNS Redirection box.

DD-WRT Check Forced DNS Redirection

3. Click Apply Settings at the bottom of the page and then wait a full minute and power the FlashRouter off and back on. Reconnect to the FlashRouter’s network once it boots back up and then make sure you are connected to VPN by going to https://whatismyipaddress.com then perform the DNS leak test again.

Adding your VPN provider’s DNS servers to the router’s configuration can be helpful as well. The DNS servers are typically found on the VPN provider’s website or you can reach out to their team for a recommendation of what DNS servers to enter.
