Hello everyone!
I'm trying to use my old laptop as an air gap devices, how do I know if it's air gapped because I already used it before for internet connection but but it has been a very very long time and I also removed the wifi adapter so it can be er go online again.
Thanks for your help
You should also plan on how are you going to transfer the unsigned/signed transaction to/from your offline laptop.
After you install the new OS, and configure the way you want it, you should physically disable all
ports, USB, HDMI, Ethernet, SD card reader, Wifi/WWAN, etc.
(Unless you carry it around 24/7 and you sleep with it, LOL).
Use QR codes and laptop cameras to transfer the data between your air gapped computers.
