Cannot Connect To Network
If your SD WLAN Module 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 the problem is likely to be caused by a configuration mismatch of:
- Network Name (The SD WLAN Module Network Name (SSID) is case-sensitive).
- Encryption Key of the AP that you try to make a connection.
Other causes may be:
- No driver loaded.
- Station not authorized to access network.
- SD WLAN Module 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 to make a connection. If you do not see any APs in the AP list field, there
might be no active AP nearby. Please move around or change the PDA orientations.
Cannot Find the AP
Check the available access point in the neighborhood the system will scan automatically.
If the access point requires WEP key, input the same WEP key then try to make a
connection 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.
The System is Very Slow
Some devices with non-powerful CPU may suffer their performance significantly. If the
system is very slow, go to check:
- If you are opening too many windows close them please.
- Change the antenna orientation for better signal reception.
- Check the signal strength if it is weak move toward the AP.
SD WLAN Module Does Not Operate After Returning From the Stand-
by or Sleeping Mode
This may happen when the driver is not functioning. Please try to remove and reinstall
the SD WLAN Module driver that might solve the problem.
