If I understand what you're saying,
the following conditions are true:
- router reboot makes router unable to
connect to other devices on the LAN
that connect to it via wireless
- reboot of devices restores
connectivity to router
- devices have static IP addresses on LAN
.
The first three items are true.
- when devices are unable to
communicate with router they can
communicate with other devices on the
network
.
I do not think the last statement is
true but the cameras and the printer do
not normally communicate between
themselves, I guess "I dunno?"
A sticking point for me, assuming I am
not missing something, is that other
devices can communicate with each
other over the wireless link provided
by the router but the router can't see
any of them. That is really strange.
I would recommend restarting the
firewall service but the fact
rebooting a device makes things work
again seems to indicate the firewall
isn't the problem.
The fact rebooting a device, an
external entity, causes the router to
be able to communicate with it again
might indicate that reconnecting to
the wireless access point is what
kicks things back into gear. I know
that a reboot will do this by default
(grasping at straws here), but have
you tried disabling/enabling the
wireless service on the router after
it has fully rebooted to see if that
has any effect? Maybe the run level
it is being started at has something
to do with the problem. Also, it
might be interesting to execute "arp
-a" on the router both before and
after it reboots to see what results
you get.

Reboot router:

Note: This morning's tests are using the
original Linksys E3000 router and Tomato
1.28 which was in use when the problem
first appeared. Just thought I needed to
go back and reassure myself that the
replacement Buffalo/OpenWRT router
wasn't introducing new problems.
The more I look into this the more
puzzled I become, presently the router
is connected to my portable which I just
booted as a trial, and an Apple Watch,
but it wont connect to my Brother
Printer. That will require a wired
connection to investigate. It also does
not connect to the remote "IP" cameras
until I "re-cycle" the ac power, I just
did that on the nearest one and it came
up, but not the printer.
I may have to live with what I have
until F-24 comes along.
Thanks for considering this,
Bob
