What are some extra steps I can take to secure my network?

· ·

DD-WRT open source firmware removes many firmware vulnerabilities and backdoor access issues that may cause problems in stock firmware. DD-WRT is also updated more frequently than stock firmware, so be sure to always check with the FlashRouter support team to see which DD-WRT build we recommend for the highest level of security for your router at any time.

Aside from avoiding common issues and flaws with stock firmware, DD-WRT give you more control over the firmware settings and allows you to take some extra steps to really lock down your network security. In this article we highlight additional options for WiFi network security and also preventative measures for remote execution attacks.

Why is my router not connecting to internet?

· ·

Router not connecting to the internet? Follow these simple steps!

  1. Make sure that you are not setting a WAN IP of 0.0.0.0 in the top right corner of your FlashRouter DD-WRT settings. If you do, then make sure your FlashRouter is wired correctly for Internet.
  2. Try power cycling your ISP modem, FlashRouter and any other router that may be in the setup. Power the modem back on first, wait for it to boot up fully, and then power the FlashRouter back on.
  3. Make sure you do not have Global Kill Switch enabled in the FlashRouters Privacy App and if you do make sure your VPN status is Connected.

Why is the power light on my FlashRouter blinking?

· ·

A slowly blinking power light means that the FlashRouter was somehow put into Rescue/Restore/Recovery Mode. This usually happens if the reset button was held down for too long.

This may also happen if you have incorrectly tried to update the firmware on your FlashRouter. The first thing to try is a simple reboot of the router to see if it exits restore mode.

If a reboot does not clear up the issue then try to reset and reconfigure your FlashRouter.

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.
