Planet Technology 802.11g Wireless USB Adapter WLU-356L - Manual (Page 23)

Chapter 4 Troubleshooting
1. The PLANET WL-U356L does not work properly.
a. Reinsert the PLANET WL-U356L into your PC’s .
b. Right click on My Computer and select Properties. Select the device manager and click
on the Network Adapter. You will find the Adapter if it is installed successfully. If you see the
yellow exclamation mark, the resources are conflicting. You will see the status of the
Adapter. If there is a yellow question mark, please check the following:
Make sure that your PC has a free IRQ (Interrupt Request, a hardware interrupt on a
PC.)
Make sure that you have inserted the right adapter and installed the proper driver.
c. If the Adapter does not function after attempting the above steps, remove the adapter
and do the following:
Uninstall the driver software from your PC.
Restart your PC and repeat the hardware and software installation as specified in
this User Guide.
2. I cannot communicate with the other computers linked via Ethernet in the
Infrastructure configuration.
a. Make sure that the PC to which the Adapter is associated is powered on.
b. Make sure that your Adapter is configured on the same channel and with the same
security options as with the other computers in the Infrastructure configuration.
3. What should I do when the computer with the Adapter installed is unable to connect
to the wireless network and/or the Internet?
a. Check that the LED indicators for the broadband modem are indicating normal activity. If
not, there may be a problem with the broadband connection.
b. Check that the LED indicators on the wireless router are functioning properly. If not,
check that the AC power and Ethernet cables are firmly connected.
c. Check that the IP address, subnet mask, gateway, and DNS settings are correctly
entered for the network.
d. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on
the settings for the wireless clients and access points.
e. In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note
that it might be necessary to set up one client to establish a BSS (Basic Service Set) and
wait briefly before setting up other clients. This prevents several clients from trying to
establish a BSS at the same time, which can result in multiple singular BSSs being
established, rather than a single BSS with multiple clients associated to it.
f. Check that the Network Connection for the wireless client is configured properly.
