I have a Dell M6700 Precision laptop that can only connect at 100MB to an ethernet network, even though it has a gigabit ethernet card.  I've checked my network cables, and can plug another laptop in and it connects at 1gigabit.  I've tried reinstalling the drivers from the Dell.com/support web page.  I've udated the bios.  I've checked that the network driver is on autonegotiate.  I've unchecked the "save power by slowing down the connection" option.

Whats happening if you set it manually to 1 gigabit within the driver options? Test the speed over the network with a system which capable to deliver more than 10 Mb/s over LAN once with autonegotiate options on so it should transfer nearly 10 Mb/s and the second time with 1gigabit mode set manually. Maybe its automatic discovery is not ok or its a combination of cable and nic/hardware, which is not occuring on other hardware.

>can plug another laptop in and it connects at 1gigabit.

Also a M6700?

You can only connect at gigabit speed only if both ends of the of the network is working at gigabit speed.
If you force it to run at gigabit manually and the other side of the network is not running at gigabit then you will not be able to connect to the network period.

I have seen this with Dell laptops before, when the laptop is running on battery power, it will automatically drop the NIC speed to 100mpbs, can you try it with the laptop powered up?

If this works, you would need to adjust the 'on battery' settings under power saving (or power management).

Saschao:  When I try to manually set the speed to 1 gig, it does not connect to the ethernet network at all.

nattygreg: I've got a 1gig switch we are connecting to, I've connected at 1 gig with another computer.

colditzz: I have been working with the laptop plugged into the wall outlet power.  I looked at the power settings on the driver.  I looked at the power settings in the actual control panel.  All the various power savings settings are disabled or set to maximum power useage.

At this point I'll contact Dell tech support, and see if there is something wrong with the hardware.

The Dell Tech came onsite, spent a couple hours attempting to fix it, and in the end I had to send the laptop to Dell to get it fixed.  Got it back just now, and the 1 Gig network is working.
