Troubleshooting (Advanced)
• Wireless LAN power supply
If is displayed on the notification area, slide the wireless switch to the right (ON).
• IEEE802.11a settings
Even if the wireless LAN is on, IEEE802.11a may be set to disable. If IEEE802.11a is to
be used, change this setting to enable. (
This computer uses channels 1 through 11
point.

In the case of wireless communications, the frequency band being used can be divided into segments, so that different communications
can be conducted on each band segment. A "Channel" refers to the individual frequency bandwidth divisions.
Cannot communicate with the access point
Using the following procedure, confirm whether the computer's protocol settings are correct (only when using TCP/IP).
When is displayed on the notification area:
A
Right-click
When is not displayed on the notification area:
Click [start] - [Control Panel] - [Network and Internet Connections] - [Network Connections].
Right-click [Wireless Network Connection], and click [Properties] - [General] - [Internet Protocol (TCP/IP)] -
B
[Properties].
Confirm the protocol settings, such as IP address, and do the settings properly again.
C
Depending on the access point and settings, access may not be accepted unless the computer's MAC address is regis-
tered beforehand. In this case, check the computer's MAC address (
ing instructions of the access point.
The communications speed is low
Communication speed may decrease if, aside from the access point to which this computer is connected, there is another
access point nearby using the same channel or a similar channel. Change the channel on the connection access point,
and check to see if the speed recovers. Confirm method for changing channels using the access point manual.
The communications speed may be reduced for the following reasons. Shorten the distance between the computer and
the access point.
• IEEE802.11g or IEEE802.11b may be affected by a microwave oven or similar, reducing the communications speed
while the microwave oven is in operation.
• IEEE802.11a is more susceptible to interference than IEEE802.11g or IEEE802.11b, and therefore the communications
speed may be reduced if there is a wall between the computer and the access point or if the computer is further away.
