Dealing with Problems (Advanced)
Communication speed decreases 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 rate may drop while a microwave oven is being used
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
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 [CPU Idle Setting] to [Performance] (Î page 144)
Unable to connect to a network z Is the IP address of the access point wrong?
Following the operating instructions of the access point, set the IP address of
the access point again correctly
Cannot communicate via an ADSL, or
cable modem
z Check to see whether IP address and DHCP server settings are set as
indicated by the ISP provider
