Troubleshooting (Advanced)
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.
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.
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
Set the wireless adapter setting of the current power plan to [Maximum Performance].
A
Click
(Start) - [Control Panel] - [Change battery settings].
B
Click [Change plan settings] of the current power plan, and click [Change advanced power settings].
C
Double-click [Wireless Adapter Settings], and double-click [Power Saving Mode], and set [On battery] and
[Plugged in] to [Maximum Performance].
Cannot set wireless LAN to [Enable] or [Disable]
z
It may become impossible to set the wireless LAN to [Enable] or [Disable] if these settings are changed repeatedly on the
[Network Connections] screen. In this case, restart the computer.
z
Press
F9
in the Setup Utility. This will restore the Setup Utility’s settings to their default values (except the password set-
tings).
