The issue is my Elitebook 8530p (approx 2 yrs old) will not connect at gigabit speed. Running Win7 x64, latest windows updates, latest bios, latest nic drivers from intel (tried from hp site too).
The nic is an Intel 82567LM (Gigabit Network Connection).
Whenever it's set to Auto Negotiate on a gigabit network, it connects at 100/Full.
If I set it to Gigabit/Full it reports no network cable connected.
My desktop (atheros card) and another laptop (Intel 82579LM) using the same cable and same switch port connect at gigabit with no trouble.
Cables I'm testing with are cat5e. Have tried direct connection between laptops, as well as with the switch, symptoms remain the same.
I have the intel proset features installed and run the diag tests on the properties of the nic, comes back with no issues.
Checked all the advanced properties compared the laptop which works fine - all the same.
I have checked through the bios in case there was a limit set there - can't see anything.
I do have vmware workstation installed, which of course hooks into the network stack but I can't think that it would be the cause.
One strange thing I have come across is that if I go to safe mode with networking, I can't get to the properties of the nic - device manager freezes when I try.
My next step is to reinstall windows, or can someone suggest a (linux?) OS on a cd that I can boot and easily check how the card is behaving?
