through a computer-to-computer (Ad Hoc) network should be configured so that their IP addresses are within the same subnet range.

-If the IP address is configured to DHCP (Obtain an IP address automatically) in TCP/IP properties, IP address is configured within the same subnet range automatically.

-If the IP address is configured to static IP in TCP/IP properties, select Use the following IP address in the TCP/IP properties of the wireless adapter, configure IP address:10.0.0.1~10.0.0.254, and Subnet mask: 255.255.0.0, and then try again.

Q8 When using a computer-to-computer (Ad Hoc) network, sometimes I cannot search the access point.

AIt may happen occasionally when you are using a computer-to-computer (Ad Hoc) network connection. Even if you cannot find some access points, the computer-to-computer (Ad Hoc) network is operating properly. Click Refresh to view the latest search result.

Q9 Running Help file while running Profile Wizard in the wireless LAN program (PROSet) makes the PROSet window white.

AIt will be displayed properly when you finish the profile wizard. It dose not affect the program operation.

Q10 The network does not operate properly when both the wireless and the wired network connections are simultaneously configured with the same IP address.

AYou cannot use the wireless and the wired network connections using the same IP address simultaneously. To use either the wireless or the wired network in turn with the same IP address, you have to Disable whichever network device will not be using in the network connection of the Control Panel.

Q11 The wireless LAN does not operate properly when there are other products operating in the 2.4GHz band.

ADevices compliant with IEEE 802.11b, operate in the public frequency, ISM band. Therefore some channel interference may happen when there are other devices using the same frequency band such as a wireless video transceiver, a microwave oven, etc. If other products cause channel interference, changing the AP channel is recommended.
