It's the standard > built-in NIC by Lenovo on the mainboard. I also have a T60p (though a different model/type number). Note that the BIOSes for the T60p have historically documented numerous changes to how the NIC is initialised and "fiddled with", **especially** if PXE booting is enabled (regardless if a PXE boot itself is performed or not). My employer sent a company-wide message to all owners of the T60p asking that they upgrade their BIOS solely to address link negotiation failures occasionally seen when PXE booting. Meaning: I would not be surprised if this issue proved to be something specific to Lenovo laptops, possibly this model. When I return to work on Wednesday night, I'll try to reproduce what you see (we have Juniper, Cisco, Extreme, and Netgear switches there), then bring the laptop home and test against a D-Link switch, as well as my ProCurve. I can tell you that I have absolutely no problems under Windows Vista when pulling the CAT5 cable out and reinserting it; and yes, DHCP is used. (I do this literally on a nightly basis, which is how/why I'm so sure.) -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
