NIC link speed either 10 or 100Mbps

Does anyone know why whenever i disconnected the AC power (and use battery only), my link speed drops to 10Mbps. when power plugged in, it's 100Mbps. Machine is Dell Latitude E6400 brand new.

Ps: This is not OS specific i don't think, Vista and Xp have this problem so i'd more Windows 7 too.

As this issue, (or is it a feature? ), is OS independent I have to assume that it is a bios feature, included to reduce power use on battery power.

If this is correct there may or may not be an option to select this in the power management options in the bios, (normally press DEL on startup), the control may also be available from a specific DELL utility shipped with the laptop.

As this unit is stated as Windows 7 compatible, it is possible that this will be an option in the modified mobility centre that will be shipped with their version of windows 7 when available

Bios is a great place to check. In the device settings but also in power management too. But if not, check the properties for the NIC in the device manager inside Windows. On the advanced tab will probably be a setting for link speed. Or there may be an alternate setting there affecting this.

Problem fixed updating of driver. It seems Dell needs to update their drivers inventory with the latest from the vendor's (Intel).
