Q
When connecting to a computer-to-computer (Ad Hoc) network, I cannot
connect to another computer on the same computer-to-computer network.
A1 Make sure that the security settings and network name of the computer-to-
computer (Ad Hoc) network are correct.
A2 Check the TCP/IP properties of the computers to be connected through the
computer-to-computer (Ad Hoc) network. All computers to be connected through
the computer-to-computer (Ad Hoc) network should be configured so that their IP
addresses are within the same subnet range.
● If the TCP/IP Settings are configured to DHCP, the address is automatically
configured to an address within the subnet IP range. This will take about 2~3
minutes.
● If the IP address is configured to a static IP in the TCP/IP properties, select
Use the following IP address in the TCP/IP properties of the wireless adapter,
configure an IP address between 10.0.0.1~10.0.0.254, and a Subnet mask of
255.255.255.0, and try again.
● A fixed IP is recommended for a small-sized network.
● If you are using a DHCP IP address, the system boot time may be extended.
A3 You have to register the IP address allocated for the wireless adapter as a 'Trusted
IP' in McAfee SecurityCenter.
Click McAfee SecurityCenter > Advanced menu > Configure > Internet and
Network > Advanced > Trusted and Banned IPs, and register the IP address or
IP address range as a Trusted IP address.
