The Link creates two separate Wi-Fi networks -- a 2.4 GHz network and a 5 GHz network -- and the default password is based on the Link's serial number, as described in the Quick Start Guide in this article.
Since the networks are separate, each one can have different security settings; for example:
- the 2.4 GHz network could have no password set and security disabled, while the 5 GHz network could have a password.
- both the 2.4 and 5 GHz networks could have security enabled, but the 2.4 GHz network could have a different password that the 5 GHz network.
It is strongly suggested that the default password is changed to prevent unauthorized users from logging in to the Link's Wi-Fi network and viewing devices connected to the Link's network.
NOTE: if client devices like a Serv Pro or Cube are already connected to the Wi-Fi network of the Link where you're going to change the password, you will lose access to those client devices through the Link until they're updated with the new password.
Therefore, you may want to log in to each client device through the Link's network before adjusting the password on the Link, and change the configuration on the client device to use the new network password so that the client is already searching for the Link's updated network and will more easily reconnect.
1. Log in to the Link's Web UI as described in this article.
2. Select Network, then Wireless.
3. Options for both the 2.4 GHz and 5 GHz Wi-Fi networks are shown; click the Configure button specific to 2.4 or 5 GHz network that you wish to change.
4. Under the Interface Configuration section, select Wireless Security.
5. Options for Encryption, Cipher and Key are shown. For Encryption, the default and recommended setting is WPA2-PSK. For Cipher, leave this at the default of "auto".
6. In the Key field, clear the existing password (if present) and enter the new network passphrase, which must be a minimum of 8 characters and a maximum of 63 characters. The characters you type will be obscured by grey dots, but you can double check your entry by clicking the green circular arrows to the right of the Key field before saving the new password.
7. Click the Save button if you are adjusting other settings on the Link and will apply the changes later, or the Save & Apply button to have the new Wi-Fi network password take effect immediately.
