Wireless communication between different rooms or floors is generally poor. Adjust the
location of the devices.

The wireless channel to be used may be limited depending on wireless network devices
installed in the computer. Refer to the manual provided with your computer or your wireless
network device to specify the valid wireless channel.

communicate with the computer, confirmed in Check 9.
If not, change the channel set to the access point.
Check 11: Make sure that the firewall of the security software is disabled.
