11.0 Appendix D – Wireless Troubleshooting
The main challenge is getting the 802.11b equipped Crane Scale to associate with a Wireless Access Point (WAP).
Once this is accomplished, the Crane Scale can be further configured by using the Scale Discovery Utility.
The settings below are the default settings that the Crane Scale will attempt to look for in an access point. Once the
Crane Scale has associated these settings, they can be changed, provided they are changed on the Crane Scale AND
the access point. At this point, encryption and authentication can be set up.
Access Point Settings (Case Sensitive):
SSID: Connect
Authentication: none (i.e. open) Encryption: none
Channel: Auto (1, 6, 11 preferred)
Mode: Infrastructure (as opposed to Ad Hoc) DHCP server: enabled
The Crane Scale by default will look for an access point with an SSID of “Connect.” If it can't find “Connect” it will
then look for an Ad Hoc network with an SSID of “Connect.” If that fails it will then associate with the strongest
unencrypted access point signal regardless of SSID. If there are more than one access points, the Crane Scale will
attempt to associate with the SSID of “Connect,” regardless of signal strength. The Crane Scale needs an access
point without authentication or encryption. It will not be able to associate if either of them are enabled. It can
associate with any channel, but 1, 6, or 11 are preferred (assuming North America). The Crane Scale by default will
look for an access point in Infrastructure mode. It will come up in “BSS_Join” mode.
Once the Crane Scale has successfully associated with the access point, assuming that the module has not been
assigned a static IP address, it will attempt to acquire a dynamic IP address from any available DHCP server on the
network.
OTHER TROUBLESHOOTING TIPS
• Make sure the AP is running in mixed or “B mode” (802.11b). If it is running in "G Mode" (802.11G) only the
Crane Scale module will not be able to associate with it as it can only do “B mode” (11 Mbps).
• If problems continue, then try to force the Crane Scale to associate with the desired access point. Remove the
antenna from the Crane Scale and move it within a few inches of the desired access point. Check the above
settings on the access point. If have any other access points in the area might want to power them off.
• Make sure the access point is not blocking multi-cast IP traffic. The Scale Discovery Utility uses multi-cast IP to
find and configure scale network settings.
• Make sure the access point being used has the newest firmware loaded onto it. In rare circumstances, errors in
the access point’s firmware can impede communications.
