How long does the cracking process take? I remember WEP only taking 10 minutes using aircrack-ng in BackTrace... I imagine this takes substantially longer.
So I don't have experience with WPA cracking, but if the access point has WPS (the click to connect button) you can sniff handshakes on the network and crack the WPA password it in relatively no time. In my experience this has usually been under 10 minutes.

#124,733,979 out of the 14,344,391 passwords (33%) in the rockyou.txt dictionary file used for cracking in this guide are too short to be WPA2 passwords, which have a minimum length of 8 characters. Are aircrack and/or hashcat smart enough to not bother hashing those short passwords?

#13I attempted to do this once and it turned out to be monumentally difficult. I got as far as setting up a bootable kali thumb drive before getting stopped in my tracks by hardware incompatibilities and unexpected behaviors and errors. These articles make it sounds a LOT easier than it is. I was very disappointed because I was really excited about it.
It was almost easier to automate a brute force, sit back and wait.

It's not for the faint of heart or faint of technical skill - different drivers have different behaviors and ways to enter the various capture and raw packet modes needed to do this. Personally, as long as I stick to supported chipsets, I've almost never had an issue.

#15Just so nobody freaks out, this is cracking weak passwords, not broken WPA.
I have myself cracked countless WiFi passwords when security testing. It's easy if the passwords are bad, which is maybe 90% of the time for home networks and 60% for businesses. The attack is completely passive if you don't want to be noticed, and with a cheap dish you can pickup both ends of the handshakes from up to around a quarter mile away (line of sight).

#16I'm not sure why this is amazing enough to make the first page but W/E it's HN :). Just so less informed are aware, this has been feasible for maybe 7 years (since GPU calculation became possible). Just so nobody freaks out, this is cracking weak passwords, not broken WPA.

I beg to differ. The fact that WPA is subject to a passive attack at all is a defect. It should use a PAKE, which would entirely avoid this type of attack.
There are simple balanced PAKE protocols that would do the trick. DH-EKE, SPAKE2, J-PAKE, and even the venerable SRP would all work. I believe that several are old enough that no patents are possible, and, even when WPA was standardized, something should have been available.

Have you found a wifi card that will work on any laptop or desktop?

although some of the reviews seem to indicate there may have been a change in chipset/drivers. I wish you luck!

Is 10 characters considered weak for mixed case letters, numbers, plus punctuation now?

I've had great luck with this wireless card. Works out of the box on any linux distro I've used it with. I bought it specifically for its aircrack compatibility (packet injection and monitor mode). https://www.amazon.com/Alfa-AWUSO36NH-Wireless-Long-Rang-Net... although some of the reviews seem to indicate there may have been a change in chipset/drivers.

It was a pain the get working on my Raspberry Pi, I had to try several different drivers and edit a Makefile to get it to compile. But I did eventually get it working as an AP, there's a script called create_ap which is very nice to painlessly run an AP on Linux.
