I suddenly lost the wifi capability of my ThinkPad E145. The easy fixes suggested on forums did not work. System is up to date (update, upgrade, autoremove done) and there is wired internet on this computer and wifi on other devices.
Output of sudo lshw -class network is:

The "Additional drivers" section of Software&Updates shows:
Broadcom Inc. and subsidiaries: BCM43142802.11b/g/n
- Broadcom 802.11 Linux STA wireless driver source from: bcmwl-kernel-source (closed)
- Device not used (This is selected)
When I want to switch (back) to the Broadcom driver, I get the following message:
"pk-client-error-quark: Error while installing package: installed bcmwl-kernel-source package post-installation script subprocess returned error exit status 10(313)"
Your answers and comments are greatly appreciated!
