cannot turn autonegotiation off in atheros ar8151 ethernet card

My isp requires me to turn autonegotiation off and use 10mbps full duplex as connection type, I do that for my laptop using ethtool

 #ethtool -s eth0 autoneg off speed 10 duplex full 

And i can successfully use the internet but, my desktop has a atheros ar8151 using the atl1c driver and if give the same command in ethtool it does not change autonegotiation to off. Although it says autonegotiation advertised is off, but autonegotiation status still remains on.
This cause serious packet loses and i can't use the internet.
Is this a kernel bug? or the alt1c driver? I am facing the same problem in ubuntu 12.04 using the 3.2 kernel

MoonSwan, he's talking about a wired device, not wireless.
