This guide shows you how to reset your Westell A90-9100EM15-10 router. A router reset is very different than a router reboot. Rebooting a router is simply turning it off and back on again. However, when you reset a router you, return it back to its factory default settings.

Warning: Proceed with caution; resetting your router can be a major headache. When you reset your router, the following will happen.

  • The router's login credentials are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Any ISP settings saved in your router will be removed. You may have to contact your ISP.
  • Any firewall settings, parental controls, or port forwards that you have configured will be removed.

A router reset is the last step you should take in recovering your router's password. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN faster than ever deal!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

There is usually a small reset button located on either the back or the bottom of a router. Most reset buttons look like this:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. You may need a paper clip to push the reset button.

Watch the front panel lights while you hold the reset button down for at least 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Remember, this will erase everything you have previously done to this Westell A90-9100EM15-10 router.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the Westell A90-9100EM15-10

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. We have a A90-9100EM15-10 Login Guide with all this information ready for you.

Change Your Password

After logging in to your router for the first time, you need to change your router's password. It is a huge security risk to leave your router's password set to the factory default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
