6.1 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.
Monitor battery usage and charge/replace batteries
as necessary.
Light precipitation or fog beginning after initial
deployment of the mesh 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 mobile 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 mobile wireless client 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 mobile wireless client that moves beyond the
range of the mesh 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 BreadCrumb configuration
has
Enable Access Point
checked. This is
off by default.
● 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 client's wireless card is in
"Infrastructure" or "Access Point" mode,
and not in "Ad Hoc" mode. Scan for the
default ESSID "rajant" (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.
