what i've done far:

- deleted rules file , restarted udev, didn't work
- manually downloaded bcmwl-kernel-source_5.100.82.38+bdcom-0ubuntu4 , 0ubuntu6 off of launch pad jockey, both older current version of broadcom driver installed.

again, wireless never not working, during installation. randomly stopped working today when booted up.

ideas of can do? there manual way of me pulling recent driver (i'm assuming driver issue due card being "unclaimed"), putting on usb, , loading manually? again don't have ethernet port.
