Troubleshooting (Advanced)
B
Right-click [Wireless Network Connection], and click [Properties] - [General] - [Internet Protocol (TCP/IP)] -
[Properties].
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.
z
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.
z
When using a wireless LAN in an environment that combines both IEEE802.11g and IEEE802.11b, communication speed
when using IEEE802.11g may decrease.
z
If you use a best-effort type service for internet connection, the communication speed may become slower than the nomi-
nal speed depending on the operating conditions.
z
Using the CPU Idle Setting to set to [Performance] may improve this problem.

Communications with access point are cut off
z
Shorten the distance between the computer and the access point, and try the detection again.
z
If there are multiple access points aside from the access point to which this computer is connected, confirm that different
channels have been set for each access point.
z
Using the CPU Idle Setting to set to [Performance] may improve this problem.
