I have a Toshiba Satellite PSAG8U-04001W.

No eth* interface shows up on ifconfig.

$ ifconfig -a

Even more surprinsingly, neither lshw nor lspci shows anything related to wired ethernet controller/adapter: lshw:

Why is my laptop's wired ethernet not showing? How can I debug this?

The installation of Debian wasn't originally on this system: it was on an older laptop whose motherboard fried, so I rescued the hard drive as well as the Debian installation. However, I doubt this should have anything to do with lspci not even detecting the wired eth controller.

Are you sure that the wired network card hasn't been disabled in the BIOS? –  Cristian Ciupitu Jun 19 at 1:48
    
The last time I checked this Toshiba bios had a pretty limited set of options, and I don't recall anything about the network card. But I will check again. –  user84207 Jun 19 at 1:52
    
actually, you were right! apparently there is an option to disable something like "built-in LAN", which was checked. Can you please add your comment as an answer? –  user84207 Jun 19 at 2:40
