Check whether the router
is not physically displaced. And All the access points
are within the range of the router. You can fix the
problem by changing the place of either the router
or the access points.
If you are using the router having
an internal antenna then you can use an external antenna
with that to increase the range and performance of
the router.
Monitor the strength of the signal
of the router. And if the signal distorts or loses
at certain point then identify those points.
Most importantly, check whether the
ip address are configured properly both at the terminals
and the router end.
Check that routing table is up to
date. Up to date routing information is very essential.
As if the routing table is not up to date then whole
of the routing process gets collapse. And the data
is not transmitted. So check for proper routing table,
the addresses of the receiving nodes, and timely updates
from those terminals.
