You are now directed to a page similar to the one you see above. Clicking the Wi-Fi Protected Setup button at the top of the page takes you to the WPS page. Do not use WPS. It can be a weak link in the security of your network. If you are able, we recommend disabling WPS.

Click the radio button at the top of the page labeled Manual.

The first setting that needs to be changed is called the Network Name (SSID). This is a name you create in order to identify your local network. It's not important what you enter here but it is recommended that you avoid personal information. Read more on this topic at our Wireless Name Guide.

Under that is the Radio Band. Set this to Auto - 20/40MHz Channel.

Now, use the Wide Channel drop down list to choose channel 6. Then in the Standard Channel list, choose either channel 1 or 11. Learn why you should only use these three channels in our WiFi Channels Guide.

When you are done making changes on this page, click the Save Settings button.

First, set the Security Mode to WPA2 Personal. This is the most secure option available right now. Learn more in our WEP vs. WPA guide.

Second is the Encryption. For the best security, use AES.

The last thing that needs to be changed is the Passphrase. This is the password you type into any wireless device you want to connect to your network. Make this password as strong as possible by using a minimum of 14-20 characters. Don't forget that you can and should use symbols, numbers, and letters in this password. Learn more tips in our Choosing a Strong Password Guide.

That's it, you are done, just don't forget to click the Save Settings button before you exit.

Possible Problems when Changing your WiFi Settings

After making these changes to your router you will almost definitely have to reconnect any previously connected devices. This is usually done at the device itself and not at your computer.
