6.1 BREADCRUMB WIRELESS NETWORK
6.1.1 SPORADIC NETWORK CONNECTIVITY
Table 4. Sporadic Network Connectivity Issues
Problem Resolution
As a BreadCrumb device’s battery approaches
exhaustion, network connectivity will become sporadic
for the BreadCrumb device and its associated wireless
clients.
Monitory battery usage and charge/replace batteries as
necessary.
Light precipitation or fog beginning after initial
deployment of the BCWN can result in sudden sporadic
network connectivity for BreadCrumb devices and their
associated wireless clients.
Increase the density of the network by adding more
BreadCrumb devices or by moving existing
BreadCrumbs closer together.
As a wireless client moves around through the coverage
area, LOS to the BreadCrumb device can become
obstructed resulting in sporadic network connectivity
for this wireless client.
Train users to maintain LOS to known BreadCrumb
device locations. Place BreadCrumb devices
strategically to ensure coverage of areas through which
users are expected to move.
A wireless client that moves beyond the range of the
BCWN will experience sporadic, and eventually
complete, loss of network connectivity.
Drop more BreadCrumb devices as necessary to
increase range.
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 connectingby anACL.
• If the BreadCrumb devices comprising the
network have AirFortress encryption enabled,
ensure that the client does as well.
