Troubleshooting (continued)
6. Why can't I get a wireless connection? (continued)
Turn off your DWL-2200AP and the client. Turn the DWL-2200AP back on again,
and then turn on the client.
Make sure that all devices are set to Infrastructure mode.
Check that the LED indicators are indicating normal activity. If not, check that the
AC power and Ethernet cables are firmly connected.
Check that the IP address, subnet mask, and gateway settings are correctly
entered for the network.
If you are using 2.4GHz cordless phones, X-10 equipment or other home security
systems, ceiling fans, and lights, your wireless connection will degrade
dramatically or drop altogether. Try changing the channel on your DWL-2200AP,
and on all the devices in your network to avoid interference.
Keep your product away (at least 3-6 feet) from electrical devices that generate
RF noise, like microwaves, monitors, electric motors, etc.
7. I forgot my encryption key.
Reset the DWL-2200AP to its factory default settings and restore the other
devices on your network to their default settings. You may do this by pressing
the Reset button on the back of the unit. You will lose the current configuration
settings.
