I tested well all the options others than auto-neg. But the result always 
remains the same.

Do not worry about this.
The connections are good.

Every time I change a parameter on the router I change it on the switch.

It is exactly the case for me. Other router on which I try to  ping is on a 
port of the same switch and the same vlan.

I put a PC in a port of the switch on which is my 3845 and by having an 
addresse of this network I was able to ping without probleme!!
