Swapped out WiFi card, now Wired Connection is dead

[ScottyK]

Running 10.10 on a Dell Vostro 1500.

Wifi was a broadcomm 4311 chip, and wouldn't work under 11.04, so I went out and bought a new card for it (Intel Pro/wireless 3945ABG Network Connection - Network Adapter - Mini-pci Expre).

Swapped out hard drives and put in the 60GB test drive, and wireless and wired worked perfectly.

Put the primary hard drive back in, and now 10.10 is telling me that there is no wired connection.

I have a light above the RJ-45, but the "wired" tab in the network manager is greyed out.

running ifconfig produces this.

typing "sudo ifconfig eth0 up" produces this.

eth0: ERROR while getting interface flags: No such device

Model number of the internel card -

lspci | grep Ethernet
03:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)

Since I dual boot, I'm going to switch over to windows to test the new wifi card there, and to make sure the wired works.
