Common Troubleshooting Tips
LED Ac tivity
If you encounter difficulty using and/or installing your Wireless 802.11b 11Mbps SDIO Card
product, the error may be related to various causes :
- Out-of range situation, which prevents the WL11-SD from establishing a wireless connection with the
network.
- Configuration mismatch, which prevents the WL11-SD from establishing a wireless connection with the
(correct) network.
- Absence of, or conflict of the WL11-SD Driver .
- A problem or conflict with the WL11-SD socket from powering on.
- A conflict of the WL11-SD hardware with another device.
The starting point to troubleshoot problems with your WL11-SD is looking at the LED activity of the
WL11-SD.
LED Activity
 The power LED will be blank when the WL11-SD is properly inserted but not transmitting/receving
data.
 The Act LED will be blinking Blue when transmitting/receiving wireless data.

If your WL11-SD seems to be working fine, but you are not able to connect to the network, this error might
be due to a configuration mismatch.
For example if LED of your WL11-SD lights, the problem is likely to
be caused by a configuration mismatch of :
- Network Name (The WL11-SD Network Name is case-sensitive).
- Encryption Key
Other causes may be :
- No driver loaded.
- Station not authorized to access network.
- WL11-SD defect.
The most common cause is simple mistake. First check whether the card is inserted properly or not. Check
whether any APs are available or not. If you see many APs, select any of one those APs and click connect.
If you don't see any APs click Rescan Button. If you still don’t see AP list after refscanning, it is possible
that no active AP is nearby. You may be in the dead zone. Move around or change the PDA orientations. It
may help.
Ca nno t Find the AP
Check the available access point in the neighborhood by clicking the Site Survey tab in the utility. If the
access point requires WEP key, input the same WEP key then try to connect again. If you do not know the
WEP key, contact the system administrator to obtain the appropriate key.
For identifying the specific AP, check the wireless networks available in the neighborhood. If the AP
shows ESSID, use the same ESSID to connect the AP. ESSID is assigned to the specific AP for that
purpose.
