
Confirm that the SSID (network name) is set properly. To connect
to a wireless LAN access point, set the SSID to be the same as the
ID of the access point.

With data encryption, confirm that the encryption key is set
correctly. Set a specific encryption key for all wireless LAN access
points and computers connected to N22A.

Check if the environment is set properly. Set the environment again
if necessary.
Communication is disabled intermittently or the
communication speed is too late.

The wireless LAN device to be connected may be located too far
from N22A. Check the radio wave environment. In poor radio wave
environment, make the wireless LAN device close to N22A.
The possible distance between N22A and a wireless LAN device
varies depending on device specification.

If one or more wireless devices only conforming to IEEE802.11b
exist in a range where radio wave can be radiated to a connected
wireless LAN access point conforming to IEEE802.11g, the
communication speed for IEEE802.11g decreases.
If a wireless device only conforming to IEEE802.11b connects to
another access point, only reach of radio wave to the access point
influences the communication speed.
