How Do I Find Out My Router's WEP Key?

Updated July 20, 2017

Security is a key consideration when connecting to the Internet. All commercially available network routers have this in mind and will encourage web surfers to create a WEP (Wired Equivalent Privacy) key when setting up their devices. Wireless LANs are vulnerable to tampering due to how they connect over radio waves. WEP keys are designed to provide a measure of privacy and protection. To connect other wireless devices, it is necessary to know the router WEP key. The following steps will assist you in finding the WEP key for three popular routing devices.

Open your favourite web browsing program and go to the IP address of your router. For most Linksys VOIP routers this is Enter the user name and password you created initially for an admin login.

Click on the "Wireless" tab and then select "Wireless Security." Key #1 shown will be your WEP key. You can copy this and paste it as needed.

If you find the "Wireless Security" section has not been set up, within this window pane select WEP as the Security Mode and under WEP encryption select "128 bits 26 hex digits."

In the "Passphrase" text box, type in a secret word to help generate new WEP keys. Click on the "Generate" button and new WEP keys will be created. Ensure you copy Key #1 (or the key number designated as the default transmit key).

In the address bar of your preferred web browser, type in (if this does not work, try This will bring you to your administration program for your router. You will be prompted to enter your admin user name and password. If you have not set this previously, the default settings are "admin" as the user name and "password" as the password. Ensure you change these to secure your router administration program.

On the left-hand side of the administration page, select "Wireless Settings" under the "Setup" menu section. The "Wireless Settings" page is split into four sections. The fourth section titled "Security Encryption (WEP) Key" will list any and all keys assigned to your router. Key #1 is normally the designated default transmit key.

If you have not created a WEP key within the "Wireless Settings," you may do so by first selecting "WEP (Wired Equivalent Privacy)" under the "Security Options" section.

Under the third section, "Security Encryption (WEP)," choose "Automatic" as the "Authentication Type" and 128 bit for Encryption Strength. Type in a passphrase then click on "Generate." You will then have four WEP keys generated with the first key being the default transmit key.

Open up your web browser and type in within the address bar. Your administration program for your DIR-615 router will open. Click on the "Setup" menu selection and then choose "Wireless Settings" from the left-hand menu.

If you have previously set up your WEP data, you will see several WEP keys within the bottom section of the "Wireless Settings" page. The default WEP number will be designated; you can copy and paste this key number as needed.

If you have not previously set your WEP key, the WEP section will not show and you will need to create the keys in order to continue. Within the "Wireless Security Mode" section, click on the drop-down box and select WEP. A new section will open up immediately below the "Wireless Security Mode" area.

Change the "WEP Encryption" selection to 128 bit and leave all other settings with their default selections. Scroll up to the top of the page and click on "Save Settings." Your router will need to reset and this may take up to a minute to complete. Once done, you can log back into your router, proceed to the "Wireless Settings" area and copy the WEP key as needed.
