Use a strong wireless password to protect your Linksys wireless network from unauthorized access. To password protect the Wi-Fi network, use your router's Linksys Web interface, which should also have a highly secure password to prevent others from accessing it and changing its security settings.
Password Protect Your Wi-Fi Network
You can access the Web interface of your Linksys router from your computer over a wired or wireless connection, as long as the two devices are connected.
Open the Web browser, type 192.168.1.1 into the address field and press Enter to open the Linksys Web interface. Type the username and password into the User Name and Password fields and click OK to log in.
If you can't access the interface, someone may have changed the IP address of the router, which you can locate via the Command Prompt.
- Press Windows-X to display the Power User menu in Windows 8.1 and click Command Prompt to open it.
- Type ipconfig into the Command Prompt and press Enter to see information about your network connection.
- Find the router's IP address in the Default Gateway section and use it in the Web browser to open the Web interface.
Switch to the Wireless tab and select the Wireless Security sub tab.
Select one of the security modes from the Security Mode drop-down box. WPA2 Personal provides adequate protection for most users. WEP is an old standard that is less secure than WPA and WPA2.
Select AES -- the latest Wi-Fi encryption standard -- from the WPA Algorithms drop-down box. Select TKIP+AES if you have older devices that may not support the newer AES standard.
Type the wireless password into the WPA Shared Key field. Use a strong password to prevent an attacker from cracking it. Click Save Settings to save and apply the settings immediately.
Change the Administrator Password
Change the router's administrator password to prevent people from accessing the Web interface and changing the settings.
Select the Administration tab after you log in to the Linksys Web interface and then type a new password into the Password and Re-enter to Confirm fields. Click Save Settings to change the router's password immediately.
