5 Troubleshooting
5.1 Sporadic Network Connectivity
Table 6: 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 default
ESSID "breadcrumb54" or "breadcrumb54-
v10" (or the ESSID that you set for the
network) using the software accompanying
