The driver for wifi should be there. To make sure, please post relevant info about your wireless chip. You can obtain that by running lspci -vv | grep -i wireless
.
Yes, we are finding clues. It appears that siducer is not detecting the hardware. I saw this with stretch before installing the driver for the wifi chip; seems there was a startup message about some brcm device, if you can tell me where to find the startup messages maybe there is something to be seen. Here is the info you requested:
siducer@siduction:~$ man lspci
siducer@siduction:~$ lspci -vv | grep wireless
siducer@siduction:~$ /usr/bin/lspci -vv | grep wireless
siducer@siduction:~$ /usr/bin/lspci -vv
