Now to the issue,
I've been running NetBSD-9 since the RC1 release and was until yesterday running 9.0_STABLE.
Never had any issues with wifi.

I shall admit that I frankensteined the system a bit and for the last weeks have been running the 9 base
with the 9.99.69 kernel and modules. Also on this freak system, no issues with wifi.

As I need to have current packages, I've been using the 9.0_current repo for binary packages. But,
since J.Perking is now building current packages for HEAD, I've decided to give it a shot yesterday.
All went well setting it all up and my laptop is running.
All except for my wifi, it constantly connects and disconnects, I can't even ping to check speeds
after restarting wpa_supplicant. I have no issues with other machines connecting.
I'm writing this from a Linux box and downloading 9.0_STABLE again as the machine in its current state
is useless, I need wifi connection.
Just before I wipe it all clean, I thought I'd ask cause I know the 9.99.69 kernel had no issues on the
9 base, all configs are the same, so I wonder...

Thanks!
