Visibility 
Status:
Visible networks conveniently advertise their existence to devices 
looking for Wi-Fi networks to join. Invisible, or hidden, networks do not. 
To join an invisible network users must manually input its SSID.
Note: Making a network Invisible is not a form of security alone.
Country: Select the country in which your router resides. This will automatically 
configure the transmit power, frequencies, and available channels the 
router’s wireless radios will use. This is based on the regulation provisions 
set by each country.
Wireless 
Channel:
Select the desired channel you wish your wireless network to operate on. 
Auto is the default and recommended setting. The router will 
automatically select the clearest wireless channel available. The current

for areas with a large number of wireless networks nearby, in order to 
improve wireless transmission.
