I'm having the same problem with my
Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)
Everything was fine, but after reboot, I had no wifi connections available. The wifi controller was present in lspci output, but not in ifconfig output. Hitting hardware buttons had no effect.
After booting into 4.13.0-45-generic kernel, everything returned to normal: wifi works as earlier.
I'm posting 'apport-bug linux --save' data here. It was collected when booted into 4.15.0-24 kernel.
