I have a Lenovo e10 30, the WiFi is not working. When I go to Software and Updates under the Additional Drivers tab; this device is using an alternative driver, and the driver that it is using is the Broadcom propriety driver.
Ubuntu 18.04 does not show the wireless card, only the ethernet network is working.
Can this problem be fixed?
I have included the output for sudo lshw -c network
