Fortress Technologies BreadCrumb Wireless Network guide

	Chapter 7. Troubleshooting

Problem	Resolution
A wireless client cannot join the network.	• Ensure that BreadCrumb devices are powered
	on.
	• Ensure that the wireless card in the client
	device (laptop) is enabled. This is usually
	indicated with a blinking light on the card.
	• Ensure that the wireless card is in
	"Infrastructure" or "Access Point" mode, and
	not in "Ad Hoc" mode. Scan for the ESSID
	"breadcrumb" (or the ESSID that you set for
	the network) using the software accompanying
	your wireless card.
	• Ensure that the wireless client’s IP address
	settings are conﬁgured properly.
	• Ensure that the WEP settings on the client
	device and BreadCrumb devices match.
	• Ensure that the client device is not prevented
	from connecting by an ACL.
	• If the BreadCrumb devices comprising the
	network have AirFortress encryption enabled,
	ensure that the client does as well.
