[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] 4bpp:
I just installed the 01-10 image on a new G930W8, and am also unable to enable the wifi, which may be the same problem everybody else is experiencing. Here's the dmesg log when I try to power it up in Settings > Network & Internet:

To my eyes, it looks like the relevant segment is

[ 932.993953] dhdpcie_download_code_file: download firmware /system/vendor/etc/wifi/bcmdhd_sta.bin_c0
[ 933.069205] _dhdpcie_download_firmware: dongle nvram file download failed

No part of this error yields useful-looking hits on Google, as far as I can tell. Let me know if there are any other useful diagnostics I can procure. (I'm a proficient Linux user, but entirely inexperienced in Android or anything to do with ARM SoCs.)

For what it's worth, wlan0 seems to have been assigned a plausible-looking MAC address, at least. I'm going to proceed to try flashing the 11-30 image if some random fiddling doesn't resolve this.
