"trying to get wi-fi setup on my beagle bone or raspberry pi were hell"

Can I ask which wifi card/chipset you chose? Was it one that you researched and found out was 100% Linux compatible? Assuming you did do that and didn't find something that was barely hacked to together to have partial support did you actually find editing /etc/network/interfaces with the text below difficult?

auto wlan0

iface wlan0 inet dhcp

    wpa-ssid GUESS_WHAT_GOES_HERE

    wpa-psk PSK_MEANS_PASSWORD

I'm going to assume you chose a wifi solution that was not 100% linux compatible. One that had a weird firmware blob or something else. My point is that I watched someone spend a week trying to get a wifi card working on Linux. He called me up for help so I looked up his Laptop and wifi card. I went on Ebay and spent $7(with shipping) for a card that was 100% compatible, swapped it out and it just worked.
