Network Adapter
Note: This is an interactive test.
Network Adapter Test items:

TCP/IP Test
Tests if the TCP/IP protocol is properly configured.

Network Connection Status Test
Note: This test launches the ASUS website through the PING command. These three
reasons may cause the test to fail: (1) The current network connection is abnormal. (2)
The ASUS official website is not accessible. (3) The firewall blocked the PING
command.
Note: You can configure the proxy settings during the network test. If you are asked to
configure the proxy settings to access the ASUS official website, configure the settings in this
area. If not, ignore the proxy settings and start the test directly.
