Giving the Pi the Internet
Go to the fifth floor of Upson and stand outside the bike lab, then use the LocomotionLab wifi as detailed in Connecting to the Pi#General notes.
If you don't want to walk:
Note that for these directions, you must not be using the Pi in ad-hoc mode (see explanation here. Use Ethernet instead.
Also, note that /etc/network/interfaces must be EMPTY or deleted.
- Remember to restart the Pi after you edit /etc/network/interfaces, or changes will not take effect! You can unplug and plug in the Pi, or just run
sudo reboot. - Remember that NEITHER the ad-hoc NOR the locomotionlab wifi networks will work at all after you wipe out the /etc/network/interfaces file! The physical Ethernet cable will definitely work though. Or just plug in a monitor and keyboard.
set up a hotspot on your phone and then run these commands:
sudo ip link set dev wlan0 up
(then wait 30 seconds or however long it takes before the next command stops giving an error message. the "set up" command may print no output even if it worked)
sudo iw dev wlan0 connect -w 'NAME OF WIFI NETWORK'
(then wait about 30 seconds or so - it's fine if nothing appears)
sudo dhclient
(then wait a random number of seconds)
sudo dhclient
(yes, you have to run it again)
The Internet should come on within a minute or so.
