After reinstalling Ubuntu, my laptop's network interface has suddenly disappeared.
It's not shown anymore in lspci nor lsusb.
I tried various recent versions of Ubuntu install medias and none have recognized my network controller.
The Broadcom driver used to be available in the additional drivers settings.
If I recall correctly, it was a BCM4352.
I tried the suggestions in this post: Wifi broadcom BCM4352 not recognized after fresh install
Tried installing bcmwl-kernel-source and dkms manually from the install USB.
Nothing soft or hard blocked in rfkill.
I'm not sure what else to try.
I appreciate any help.
