WLAN Connection Is Not Established: What to Do
Error Scenario
Undefined malfunction.
Possible Cause
Radio traffic subjected to strong irradiation.
Remedy
Switch the WLAN channel setting on the access point. Find a better
location to place the WLAN products to avoid potential frequency
interference from microwaves, cordless DECT telephones or Blue-
tooth devices.
Error Scenario
You computer recognizes the network and the router, but cannot
access the network.
Possible Cause
Incorrect WLAN key
Remedy
Make sure the WLAN key is correct. If you have a WLAN access
point from the AVM FRITZ!Box family, you can find the key on the
base of the device and on the back of the installation CD. If you use
a WLAN access point from another manufacturer, please see the
documentation of this device.
Error Scenario
Two FRITZ!WLAN USB Sticks are connected directly via WLAN, but
cannot exchange any data with each other.
Possible Cause
The IP address was not assigned by Windows automatically (note:
the process can take up to 3 minutes), or the network key, work-
group or ad-hoc network names do not match.
Remedy
Make sure that the ad-hoc network name of your connection and
the network key match, and that automatic assignment of IP ad-
dresses is enabled in your operating system. The connected com-
puters must be in the same working group (for more information,
see: "Encryption" on page 27 and "Checking the IP Settings" on
page 32).
