I've updated my 4.9.0-11.12 kernel to include a small patch that hopefully will improve RTL8723BS wifi. This new kernel has been included in a respin of my 17.04 Alpha 131216 ISO.
To try the ISO download it from the link below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.
