Hi. Which network is this? WI-FI? Assuming it is tethering from an android phone.
Go to Settings > More > Tethering and portable hotspot > Touch "WI-FI hotspot" > Set up WI-FI hotspot > Touch "WPA2 PSK" and select "Open" .
Please note that your hotspot will be open for everyone to connect without a security pin.
