I finally solved the problem by getting a Belkin Gigabit Ethernet expresscard. I can now communicate with the USRP2. Still don't know why the ethernet interface on the Lenovo wouldn't work.
Thanks to all those who responded.

The results are the same. Given that the dongle is not a workable option, I still have the eth0 port not even showing connectivity. The dongle at least showed connectivity even if it can't sustain the speed. The port on the T61 is supposed to be GigE capable, but I can't get it it even show connectivity when configured with a fixed address.Al W8KHP
You might look at "ethtool" to turn off autonegotiation and nail the speed at 1000Mbits for that port.-- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
