1) From a web browser, go to “http://192.168.1.1”. Login with the username “admin” and the password “seiadmin”.

2) Click the WiFi link on the left-hand menu bar and click on “Networks”.
  – By default the two Network interfaces (2.4GHZ and 5GHz) are enabled and set to have the same Network name and password.
  – Multi-band SSID setting only allows 1 single WiFi network name, password, and encryption to exist.

3) Scroll down to 2.4GHz and 5GHz sections and from here you can change the Network Name of the router by changing the name under “SSID” line. You can then change the password of each Network interface under the “Password” line.

4) Click on the drop-down “Encryption” in the 2.4GHz or 5GHz interface sections. You can change your encryption passphrase/key here, or you can view the current one as well.
  – The default passphrase/key is the last 8 numbers of the Serial Number of the router, located on the bottom of the router.
  – Please note that this key is case sensitive.

5) Once the changes have been made click on the “Apply” button at the top to save change.
