How can I connect to the LinkZone 

network?

Select the Wi-Fi name (or the SSID) of the LinkZone 

on your wireless devices, and enter the Wi-Fi 

password. 

NOTE

 Find the default Wi-Fi name and password on 

the label inside your LinkZone.

"PIN lock" or "PUK lock" is 

displayed on the screen of the 

device connected to the LinkZone 

network.

This indicates that the SIM card is locked. 
To unlock the SIM card, log in to the web UI and enter 

the PIN code or PUK code. To obtain the PUK code, 

contact your internet service provider.

 If the PIN code is entered incorrectly 3 times, 

you will be required to enter the PUK code. If the PUK 

code is entered incorrectly 10 times, the SIM card will 

be locked permanently.
