Ad-hoc Wireless on Chromebooks / Dell CB 13

| chromeos reviews

Doing Nanowrimo again, and had given away my Toshiba CB 2 to someone who could use it more than me, so instead picked up a refurbished Dell CB 13 (i3, 4GB, 32GB SSD) on sale from the Dell depot.

What an amazing machine. A beautiful 1920x1080 screen, keyboard that is backlit and has nice tactile feedback, a trackpad that is silky smooth and feels as good as the Mac trackpads, and overall the machine performs really well (Octane abou 20k). Speakers are decent as well, although maybe a bit scratchy at the upper volume ranges. Nonetheless, the price / performance ratio on this machine is ridiculously high.

Anyway, I ended up needing to create an ad-hoc wireless network with the Chromebook, and it was not obvious how to do it on a quick search. Creating an ad hoc network does not require Crouton but does require developer mode.

Turn off wireless, and go into shell:

sudo ip wlan0 set type ibss
sudo ip link set wlan0 up
sudo iw interface ibss join your_ssid 2437
sudo ifconfig wlan0 192.168.0.1 netmask 255.255.255.0

Obviously, pick whatever SSID / IP / netmask you want. Also, this is an unsecured link, which was fine for my purposes but you may want to run wpa_supplicant for WPA.
