Sounds like you have Mac filtering on. Either turn it off or add the mac of computer three to the table.
Interesting solution.
I went into MF and discovered Comp #3 was not there though Comp #1 & #2 were as well as other addresses.
I added Comp #3 and the Comp imedietly "discovered" other items on the network. The Router.
However. While the router itself is now visible to Comp #3 (where earlier it was not, only the other two Comps through it), I still have no Internet access.
LOGS now read...
"Allowed configuration authentication by IP address (Comp #3 address)"
But still cannot access Internet.
I can however, now access the router from Comp #3, just can't get through it.
Comp #3 Diagnostic:

etc.
Also, any particular reason your using static IP instead of using DHCP in your LAN? I mean its not wrong, just curious of your reasoning.
Actually I'm not.
I have DHCP Client as my connection type.
