I have the Sony VAIO Duo 13 with Windows 10 and Ubuntu 16.04 Dual-Booted. I cannot get the internal wifi chip to work with Ubuntu. The internal chip works with Windows 10. I have tried many solutions including this one: Sony Vaio Pro Duo 13 SDIO Broadcom BCM43241 Not Recognized

I can use a usb adapter for WIFI (not desirable) so I can download anything needed if needed for a solution.

Any help would be greatly appreciated.

Some more info when my usb adapter is not plugged in (internal wifi card only):

From Windows 10 I was able to find info on the wifi adapter

Manufacturer: Broadcom

Description: Broadcom 802.11abgn Wireless SDIO Adapter

Driver version: 5.93.102.22

Physical address (MAC): (I have it but hid it for obvious reasons)

Thank you all for the assistance. I have spent 2+ days on this and finally stumbled on the solution from here: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/1777444

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install broadcom-sta-dkms
sudo reboot
