  If a wireless client can't join the Rajant Corporation Network Hardware network, here are some things to check: * Make sure the BreadCrumb devices are powered on. * Confirm the wireless card in the client device is enabled (look for a blinking light). * Verify the wireless card is in "Infrastructure" or "Access Point" mode, not "Ad Hoc" mode. Scan for the network's ESSID (default is "breadcrumb54" or "breadcrumb54-v10"). * Check that the wireless client’s IP address settings are configured correctly. * Ensure the security settings on the client device and BreadCrumb devices match. * Confirm the client device isn't blocked by an Access Control List (ACL). * If AirFortress encryption is enabled on the BreadCrumb devices, make sure it's also enabled on the client.
