Troubleshooting (Advanced)
Access point is not detected
z
Shorten the distance between the computer and the access point, and try the detection again.
z
Confirm the following settings:
• [Wireless LAN] in the [Advanced] menu of the Setup Utility
Confirm that [Wireless LAN] is set to [Enable]. (
)
• Wireless LAN power supply
Slide the wireless switch to the right (ON).
z
This computer uses channels 1 through 11
when using IEEE802.11b/g. Check the chan-
nel being used by the access point.
*3
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
z
Using the following procedure, confirm whether the computer’s protocol settings are correct (only when using TCP/IP).
A
Click
or
on the notification area, and click [Network and Sharing Center].
B
Click [Manage network connections].
C
Right-click [Wireless Network Connection] and click [Properties].
z
A standard user needs to enter an administrator password.
D
Click [Internet Protocol Version 4 (TCP/IPv4)] and click [Properties].
E
Confirm the protocol settings such as IP address, and do the settings properly again.
z
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 (
) and register it according to the operat-
ing instructions of the access point.
The communications speed is low
z
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.
