Chapter 7. Recovering the Computer
Q10 The wireless LAN does not operate properly when there are
other products operating in the 2.4GHz band.
A1 Since IEEE 802.11b and IEEE 802.11g equipment uses a common frequency or
the ISM band, channel interference may occur when a wireless video transceiver
or a microwave oven is being used. If you experience channel interference from
other equipment, it is recommended changing the channel to connect to the AP.
A2 IEEE802.11g equipment operates in hybrid mode when there is active
IEEE802.11b equipment. This may result in data rate degradation.
Q11 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 This may be caused by selecting the ‘Use IEEE 802.1x network authentication’
option when IEEE 802.1x authentication is not available.
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.
A3 If the AP is configured to ‘Use network authentication (Shared Key)’
If the AP is configured to authentication shared mode, all computers to be con-
nected should be configured as follows:
If you are using Windows XP, select network authentication(shared mode) in the
wireless network settings.
Click Start > Control Panel > Network and Internet Connections >
Network Connections
. Right-click the Wireless Network Connection icon,
and click View Available Wireless Networks > Advanced. In the
Wireless Networks tab, select an AP in the Available Networks field and click
Configure and select Network Authentication (Shared Mode).
If you are using Windows 2000, check that the network authentication mode is
configured to Share in the security settings of the wireless LAN program
(PROSet).
For more network authentication procedures, ask your AP (Access Point) adminis-
trator.
