A2 Check the TCP/IP properties of the computers to be connected through the com-
puter-to-computer (Ad Hoc) network. All of the computers to be connected
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 auto-
matically.
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, con-
figure IP address:10.0.0.1~10.0.0.254, and Subnet mask: 255.255.0.0, and
then try again.
Q8 The network does not operate properly when both the wireless
and the wired network connections are simultaneously config-
ured with the same IP address.
A You 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.
Q9 The wireless LAN does not operate properly when there are
other products operating in the 2.4GHz band.
A 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. Since the IEEE802.11g device operates in hybrid mode when
there is an IEEE 802.11b device in operation, the data rate might decrease.
Q10 An established wireless LAN connection is disconnected after
2~3 minutes, and the connection is not recovered.
A1 This may be caused by channel interference. Change the channel of the AP, and
reconnect.
A2 Selecting the "Use IEEE 802.1x network authentication" option in Windows XP
when IEEE 802.1x authentication is not used, may cause this phenomenon.
Check the properties of the AP in the wireless network settings. If the 'Use IEEE
802.1x authentication in this network' option is selected, deselect the option on
the Authentication tab.
For more detailed information about authentication server, ask your network
administrator.
