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
- when devices are unable to communicate with router they can 
communicate with other devices on the network

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.
