I have tried the mii-tool as suggested by alexander.janssen@gmx.de it did
help to some extent but I was not successful in the overall situation
I would like to elaborate the setup in more detail

A(eth0) <----->distance 2mts <---> (intel Switch 550T) <---->distance30mts
(hub) distance 20mts <--->B(eth0) (eth1 wireless card  wan) < ~ ~ ~ ~ ~ >
(eth1 wireless card wan) (eth0) <---->distance 2mts (hub) <------>distance
10mts (PC)

A(eth0) the value of this interface card as per the dmesg of the box is as
