Red face Puzzling problem with LAN cables

I replace now my old router with wireless. However one of the laptops is not wireless so I connect it with a cable.

To make the following less confusing by grammar I will use the notation:
A - old router, B - new router, C - the laptop

The old cable I have connects C and A fine.
It does not connect C to B. (LAN LEDs dont lit up and ipconfig says "cable disconnected").
BUT the connection between A and B is established fine using the same cable!
Conclusion: the problem isnt at either end of connection alone.

However there is another cable which came with B - it is alas too short (only 1m) to be convenient for me.
And it does connect C to B!!!
So the problem is not a holistic property of the B - C system either!

Any suggestions to this puzzle?

Or computer science champions against the rules of logic once again?

Heh, right now I am writing this through C - A - B network!
