Lenovo Support T450 Drivers

I'm trying to install Ubuntu Mate minimal installation using the Ubuntu 16.04 mini.iso on my ThinkPad T450s. I was able to do so on my T60, but I'm running into network config issues on this machine. For some reason, the installer is not detecting the Intel wireless card, despite the fact that the correct drivers seem to be included in the mini.iso package (iwlwifi-7265, if I'm not mistaken). It detects the ethernet interface and tries to configure that, but of course fails because it's not connected. I tried disabling ethernet in the bios to 'force' it to configure the wireless network, but then the installer just says, 'No network interfaces detected.'

I'll add that the wireless works fine with the currently installed OS, which is vanilla Ubuntu 16.04, so I can't understand why it wouldn't work with the 16.04 mini.iso.

Your Intel 7265 uses the driver iwlwifi which also requires the module iwlmvm. The mini.iso evidently provides drivers for a limited number of common networking devices.

I downloaded and extracted the mini.iso and, unfortunately, the module iwlmvm is not included. As well, when you tried to install, you got a message:

'failed to load module iwlmvm (error 256), is dynamic loading enabled?'

I know of no way, aside from a temporary ethernet connection, to get a working network interface with your Lenovo T450s.

I recently picked up a T450s to replace my T430 that took a trample and had a bent frame.

I ran into this very issue while trying to do a minimal install on the T450s. Thanks to the answer by chili555, I was able to track down a solution which would let me perform the install wirelessly from a thumb drive.

Since the iwlmvm kernel module is needed for this wireless card, where does this file come from anyway?

This module is provided by the linux-image-extra package. The mini.iso installer (as well as the Ubuntu Server ISO) doesn't seem to have this package installed for the live OS.

Once the installer fails to connect, hit 'Go Back' and select the menu option to open a shell. Check the version of the running kernel.In my case, this was 4.4.0-21-generic.

Searching for this in Ubuntu Package Search, you are able to find where you can download the linux-image-extra-4.4.0-21-generic package:

Downloading linux-image-extra-4.4.0-21-generic_4.4.0-21.37_amd64.deb to another machine (or the same one if you are planning to reinstall), extract the file:

By copying this module to a thumb drive, you can copy it somewhere on the root filesystem of the installer (which is running in memory) and insert it manually.

What's this? Checking dmesg, it looks like this module relies on symbols from another module.

If you check the output of lsmod on another machine, you can determine the other modules needed to load:

In my case, cfg80211 was already loaded on mini.iso, so all I needed to load were the following two modules (copying mac80211.ko in the same method as iwlmvm.ko):

At this stage, if you check dmesg again, you will see that iwlwifi has detected your wireless card. You can exit the shell and try to detect network hardware again, and you'll be able to complete the installation with your wireless card.

Hope this helps!
