With the last kernels (4.12.9 —> 4.12.12), I have some troubles with my WiFI.
From the 4.12.9 to the 4.12.11, I have no connection at all. With the last one (4.12.12), I lost the connection randomly. I have to restart the dhcpcd sv each 20 minutes.
Everything is ok with the previous kernel (4.11.11).
Any idea ?
