I'm currently running fedora 27 on an Acer Aspire Switch One SW1-011 (https://www.notebookcheck.info/Acer-Aspire-Switch-One-10-SW1-011-11AN.231024.0.html)

according to that link it's a Realtek RTL8723BS

 

uname -a:

When running lshw -C network it returns only my usb-ethernet adaptor

I've additionally also tried adding blacklist acer_wmi into /etc/modprobe.d/blacklist.conf without any luck

It possible that the hardware is fully proprietary or just block.

lspci -k

-k option show kernel driver handling each device as explain in the manual

then

rfkill unblock all && rm -rf /dev/rfkill && reboot

That will unblock all things from rfkill that could be block by default

Seems like you have the driver module r8723bs for the wifi loaded, judging by the the lsmod output. Does the driver say what is wrong in the output of dmesg?

If you are missing its /lib/firmware/rtlwifi/rtl8723bs_nic.bin firmware, note that you can substitute rtl8723bu_nic.bin as this part of the firmware is interchangeable between the two, and if you don't have that you can get it from however your distro delivers firmware, or from upstream: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rtlwifi
