Troubleshooting (Advanced)
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.
When using a wireless LAN in an environment that combines both IEEE802.11g and IEEE802.11b, communication speed
when using IEEE802.11g may decrease.
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
Shorten the distance between the computer and the access point, and try the detection again.
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.
Cannot set wireless LAN to [Enabled] or [Disabled]
It may become impossible to set the wireless LAN to [Enabled] or [Disabled] if these settings are changed repeatedly on
the [Network Connections] screen. In this case, restart the computer.
Press F9 in the Setup Utility. This will restore the Setup Utility's settings to their default values (except the password
settings).
