And no, I'm not talking about pirating on the internet, I'm talking about getting your internet connection to the outside world without paying or having a subscription or license. Something like a mesh network with your neighbors with the exit node being one person's high-speed fiber line, or even an exit node through a free public wifi network that you've hidden a little repeater device within range of... something like that could be interesting. I've been thinking lately of a world where decentralized networks become more common, and where people can freely use the internet without paying an ISP. What are your thoughts?

When I was in college, I rented a house just outside my budget and found I couldn't afford things like cable internet.

I had a wifi->ethernet bridge that was originally to connect my OG Xbox to a wifi network. I also had neighbors with Wifi using WEP encryption. An idea was born.

Was able to use aircrack-ng on my laptop to crack their WEP key in about 15 minutes. Plugged that key into my wifi->ethernet bridge, and then hooked that into my router. Bam, my whole house was online.

That worked for probably a year and a half.

Does aircrack ng still work?

Aircrack-ng still works as a packet sniffer and a wifi detector but breaking WPA is way more difficult than breaking WEP. No one basically uses WEP anymore.

Darn. Thank you!

WPA and WPA2 gear still has plenty of vulnerabilities.

AFAIK, yes. Though I haven't tried it with WPA3.

While WEP is dead, you can still use it to capture the WPA/2 handshake and run it through something like John the Ripper to try to recover the passphrase.

Admittedly, I haven't messed with it in years.

Either way, you still need a wireless adapter that's capable of promiscuous mode as well as a driver for it that supports packet injection (not sure how rare that is nowadays).
