I just bought Lenovo ThinkPad X201 t. I have installed Debian Jessie (testing). I was able to make working all of its hardware, but with one exception. And that is mobile broadband modem. I have checked it: it's there and correctly pluged. Mobile bradband is allowed by BIOS. When I have runned lspci the results was:

00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 02)

ff:02.3 Host bridge: Intel Corporation 1st Generation Core Processor Reserved (rev 02)

Well, not one looks like it (at least to me). If it is not there, does it mean it is a hardware problem? Because I'm pretty sure that it should be on PCI bus (not some internal USB or something else).

Thank you!

  • Try rfkill. Besides, it is the best hardware question i've ever seen.

  • I am not be sure that is on PCI exactly (try lsusb). Secondary try to search by modem name + notebook name for some drivers

It is possible that the device is blocked by rfkill. If so, this is not a hardware problem. To check out, run the rfkill(1) utility programme rfkill list. If a mobile broadband modem is listed and shown as "blocked", then unblock it with the same programme. See manuals.

rfkill is a subsystem to activate and deactivate radio transceivers. When a device is blocked by rfkill, it is not listed in PCI probing.

  • rfkill programme is provided by the rfkill debian package.
