The DIR655 is brand new (old one replaced under warranty). The hardware revision is A4 and it's on firmware 1.30WW (As shipped). I installed 1.34WW on the old one when I was trouble shooting it, but that didn't solve this problem.
I suspect the router is working as it is supposed to, assuming I've configured it correctly.
I have set up the DHCP reservations for each machine in the router.
I have not configured any network filters because everytime I do it kills internet access for everyone and I have to reset router to factory defaults to get back into it. (see attached screen shots).
When a PC is set to use DHCP it will pick up the reserved address.
When a PC is configured with an IP address it will connect to the internet, regardless of the DHCP reservation.
There are five IPs not listed in the pics. 192.168.1.1 is the file/web server, 192.168.1.4 is currently turned off for repairs. The printer is 192.168.1.31
There are also two IPhones that are occasionally used. So /28 won't be enough addresses. But thanks for the suggestion.
