running ubuntu-16.04.3-desktop-amd64

I need to completely disable wireless on my old windows tablet-PC (now running Ubuntu) preventing it from ever accessing networks wirelessly or the internet ever again, particularly after reboots. this is for security concern.

Normally you could disable the network card in the bios in a laptop or desktop motherboard, but on this tablet-PC it doesn't give me such option :< Anyone know how I could achieve this on Ubuntu, i assume for example by deleting all wireless drivers?. thx

The output of your systems dmesg might be useful in identifying your wireless controller.

You can blacklist the wireless module. Depending on your wireless card manufacturer you would blacklist a different kernel module.

For instance, on my system with a Broadcom wireless controller I would blacklist b43.

lsmod | grep b43
b43 401408 0
bcma 49152 1 b43
mac80211 659456 1 b43
cfg80211 499712 2 b43,mac80211
ssb 57344 1 b43

Atheros controllers might be ath9k or ath10k_pci.

lsmod | grep ath9k

This is a generic explanation of blacklisting. Note the EDIT for the blacklist file name changed to /etc/modprobe.d/blacklist.conf: How to blacklist kernel modules?

This is an example where someone asked the same question: https://ubuntuforums.org/showthread.php?t=1622582
