No carrier -> not a DHCP problem. Check your cables, switches, NICs or whatever.

i just shut down the both computers
I took out the cards and connected again
and sprayed them contact spray

restarted the computers

i  plug a modem to wan2 on the 2.1.5 computer and it work

i plug a computer to lan on 2.2 computer and it work

i Check the cable and its good

But I noticed that LEDs on the cards do not blink (only when connecting 2.1.5 to 2.2)
when i test it with the modem and computer they blinked

I frankly have no idea what WAN/LAN/modem/computer you are talking about or what's your computer doing on WAN. No carrier -> HW problem.  No LEDs on NIC -> HW problem.

Something a little strange

I do not know why I thought to try it

But
Instead of connecting 2.1.5 to 2.2 Directly
I connected the two of them to a switch

and it work

Why it does not work without a switch ?

Yes again, HW problem. Most likely not using crossover cable on LAN cards not capable of auto MDI/MDI-X detection.
