My home lan is set up based upon a Linksys wireless access point and

All works well until 9.30 a.m. every morning when 192.168.1.2 is taken
down and reset to 192.168.1.100, apparently by dhclient accessing the
dhcp server running on the wap.
If the computer is set up to use static addressing...it shouldn't be
running a dhclient.
There should be two ways I know of this happening...1, the computer is
set to dynamic addressing and by "static" someone is defining it as an
entry in the DHCP server to assign the same address to a particular MAC
every time, which isn't static addressing, or 2, the computer has
something, a script, running at that time that resets the network to
another config.
What's in your (and root's) crontab at that time?
Thanks to all for the interesting responses on this.
I've taken out dhclient (which took out dhcdbd with it) as I can't see any
need for it.
For the moment I'll wait until 9.30 a.m. tomorrow to see whether this alone is
enough to resolve the issue.
In view of the large input I'll post back again to report on progress.
To those suggesting a change to dhcp from static addresses, I don't think this
is a workable option for me, unless maybe going into the router and linking
machine names to the mac addresses is the way to go. I need to know the
addresses of the machines on the lan.
