To configure the TZ Wireless settings for a LAN
Select the radio button for the Wireless Guide wizard.
For international (non USA or Japan) TZ370 Wireless appliances, you are asked to select a country code when using the Wireless Guide or when you initially navigate to the DEVICE | Internal Wireless > Settings page. Be sure to select the country code for the country in which the appliance is deployed, even if you are not currently in that country.
If you select the country code for Canada, it cannot be changed except by contacting SonicWall Support.
