I have a Jetson nano that is running Ubuntu 18.04 LTS. I need internet access on the jetson. Currently, the only internet connection that I have is on my phone. I tried to tether my phone to the jetson via USB, but I cannot get internet access to the device. Jetson recognized my phone as a tethered device. lsusb gives the following output:

Bus 002 Device 002: ID 0bda:0411 Realtek Semiconductor Corp. 
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

ifconfig gives the following output:

Currently I have connected my laptop to the Jetson device via the micro-USB port on the Jetson.

  • I would problem solve the phone first. I have not had a Samsung for a few years but the phone (or tablet) does not likle to tether when the WiFi is also enabled. So assuming you intend to use your phone's actual internet connection, try switching off the WiFi and internet sharing first, then USB connect the phone, then activate USB tethering and see of you get a different result.
