I just did a dist-upgrade to kernel Linux 4.4.0-112-generic and when I rebooted I had no internet I did was not even able to see any wifi routers. I booted back into kernel Linux 4.4.0-109-generic and my wifi was fine. I am guessing there is a problem with my Broadcom wireless card with kernel Linux 4.4.0-112-generic .
Broadcom wireless BCM 4313 802.11bgn wireless network adapter
Anyone else experience problems with Linux 4.4.0-112 kernel and wireless?
