Instructions

Part One

1. Turn off blutooth on computer
2. Turn off blutooth on phone
3. Turn off Wifi on phone

Part Two

1. Turn on wifi hotspot or usb tethering

Verify!

You want to verify that you are connected to your Android hotspot. Android tether is a router that will stand up a subnet of 192.168.43.0/24 for wifi hotspot, and 192.168.42.0/24 for usb tether.

• On linux open a terminal and type ip addr

• on Windows open a cmd console and type ipconfig

• If tethering via wifi hotspot you should see an ipv4 address of 192.168.43.XX

• If tethering via usb you should see an ipv4 address of 192.168.42.XX

ACHTUNG Do Not!

• DO NOT turn on ethernet tethering
  • you probably don't have the physical equipment available to do that
• DO NOT turn on blutooth tethering
  • $#?# DUH!!
• DO NOT turn on blutooth
  • Your phone's radio hardware already has enough to do, trying to simultaneously maintain an LTE uplink to your mobile carrier and a wifi downlink to your computer
• DO NOT turn on wifi
  • Don't let your phone try to connect to something that isn't working right now
• DO NOT forget to turn off blutooth

Blutooth

If you leave blutooth on while trying to tether, your phone could get hot, your battery could go dead, and your hotspot could fail to work properly. Be surprised it it doesn't crash and soft-reboot.
