wireless not working after installing ubuntu 18.04

[phyzzy2008]

This works great once I turned off secure boot.

Yes it works great, unless like me you messed up the MOK edit at secure boot.
It works fine with secure boot off but being paranoid I would like to continue using secure boot.
Is there a way to sign the module/s in retrospect or to completely remove them so that I can rebuild them?
Or perhaps I should reinstall 18.04 from scratch because I missed the MOK at the new install reboot, though it seems to work OK.
Any advice and instruction?
Thanks, Nigel

Not that I know of.

You might ask the gurus over on General Questions; probably involving mokutils.

Thanks @praseodym
It worked for me also on my acer laptop having ubuntu 18.04

Thanks, Praseodym! I had installed the driver earlier and got the wi-fi working, but your method for changing the antenna worked even though some other methods I tried didn't. When using the wrong antenna, I had to be almost next to my router, and even then it didn't work well.

I recently purchased the HP 14-cf0014dx, and (as far as I know) the only thing that didn't work out of the box with Ubuntu 18.10 was the wi-fi. Fortunately, Bluetooth worked fine and let me use my phone as a hotspot so I could download the driver.
