Status in linux package in Ubuntu: Incomplete Bug description: I use a very low and laptop with a built in rtl8723b wifi card. I always used the driver from lwfinger on github and that one worked well. But now Ubuntu comes with a driver for this card but that does not work on normal boot. Strange thing is this driver is initialised after resume from suspend. So i blacklisted the kernel module with: echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf and used the lwfinger driver from github again. So with rtl8xxu driver wifi card does not work on normal boot but does work when recovering from suspend to ram. Thank you.
