Problems with Wireless LAN
Communications with access point are cut off
Unable to connect to a network
Cannot communicate via an ADSL, or cable modem
Cannot set wireless LAN to [Enable] or [Disable]
The communications speed may be reduced for the following reasons. Shorten the
distance between the computer and the access point.
• IEEE 802.11g or IEEE 802.11b may be affected by a microwave oven or similar,
reducing the communications speed while the microwave oven is in operation.
• IEEE 802.11a is more susceptible to interference than IEEE 802.11g or IEEE 802.11b,
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.
When using a wireless LAN in an environment that combines both IEEE802.11g and
IEEE802.11b, communication speed when using IEEE802.11g may decrease.
Using the CPU Idle Setting to set to [Performance] may improve this problem.
See "A device connected to a PC Card does not operate correctly" (
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.
Using the CPU Idle Setting to set to [Performance] may improve this problem.
See "A device connected to a PC Card does not operate correctly" (
Following the operating instructions of the access point, set the IP address of the access
point again correctly.
Check to see whether IP address and DHCP server settings are set as indicated by the
ISP provider.
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.
