rtl_usb is buggy. The fact anything that depends on it works, e.g. rtl8192cu, is nothing more than a fluke. And there's no point fixing it because it's being replaced by rtl8xxxu. You could try blacklisting rtl8192cu so rtl8xxxu is loaded. It was a very new driver back in kernel 4.4 but may work well enough although you may still have problems with connection dropping out. There was a bug in rtl8xxxu that only affected certain chipsets that existed up till around December 2016 when I reported the cause to the maintainer.
For any realtek usb wifi dongles, if a person is up to the task, I recommend blacklisting the in-kernel drivers, compiling and using the original realtek supplied driver instead. Even with rtl8xxxu, you won't get as good as performance as the original realtek driver and without documentation for the chipsets I can't see that changing anytime soon. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
