PSA: RTL8723BE users beware upgrading to kernel 4.12+ - users - Fedora Mailing-Lists

Tuesday, 29 August 2017

For anyone else with the misfortune to have a laptop with the RTL8723BE 
wifi chipset, be cautious about upgrading the kernel to 4.12 or later. 
It might still work if you use antenna 2, but I can't verify that.  In 
my case with ant_sel=1, the wifi can't see anything with the 4.12 kernel 
or higher.

I've filed https://bugzilla.redhat.com/show_bug.cgi?id=1486463 if anyone 
else wants to follow it.  There was a patch related to ant_sel not 
working that was applied to 4.13, but it was reverted due to a null 
pointer problem.
