broadcom gigabit netlink adapter won't connect at 1Gbps, auto negotiate connects at 10Mbps

Hello,

I'm very pleased with my Alienware Aurora ALX purchase, and happy to be a part of this community.  However, I do have this issue:

The Ethernet adapter won't connect at 1Gbps; here is what I've tried so far:

1) Confirmed that my router is capable of supporting Gigabit Ethernet.  I've got two other devices connected at this speed (an older PC and a NAS).

2) When I set the speed and duplex of the adapter to auto negotiate, it will only connect at 10mbps

3) I notice there is no setting for 1000Mbs in the speed and duplex options.

4) I tried 100Mb full duplex, it will connect but my Internet connection slows to less than 1Mbps (I'm on a 15Mbps connection, and testing the other PC it was able to achieve around 14Mbps).

5) I then tried 100Mb half duplex, this will also connect and my overall network performance is good.

6) I confirmed that I have the current driver from Dell. I've had the computer for 3 days (using windows 7 by the way).

7) I tried all the ports on my router and confirmed that the router side was also set to auto negotiate and not trying to force a specific speed.

I'm hoping that someone has a solution or suggestion to fix this.

Kind Regards,

Jason
