Re: Which Network Controller Card handling Wi-Fi, Bluetooth, etc., connectivities, is GNU/Linux Approved/certified, and would be (1) compatible with my HP laptop's motherboard, and (2) could replace the "Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)"

I thank Mr. Butterworth for his kind information on the wireless N
model network card.
This gives me an opportunity to suggest to the Debian Universe to have
similar such internal add-ons and a comprehensive list of internal
add-ons be made available to us users, be bought from the open market,
rather than the list of only tested laptops at
https://wiki.debian.org/InstallingDebianOn#OfficialDocumentation and
some external accessories, such as printers, scanners, etc.
A fair amount of discussion is on the thread:

The economic model is sure to survive competition given the sheer
number of FSF, GNU/Linux users, including the Debian, Arch, Manjaro,
Ubuntu, et al, users all over the world.
I have sent an email to ThinkPenguin for the wireless N model model
using their Contact webpage.
Best wishes,
