When I was installing a software, the system needed to be updated, but I forgot to turn off the kernel update. As a result, the kernel was also updated when the system was updated, from 4.9.253 to 4.9.337. However, after the upgrade was completed, the wifi driver could not be used. , recompiling cannot support this version of the kernel. How to solve it?
