# Connecting the A1 to the Internet

{% hint style="info" %}
If the timezone on the nvidia board isn’t set up properly (automatic) errors with network requests can occur. 

To solve this problem simply connect the nvidia board to a external monitor and keyboard and set the time zone to `automatic` in the `linux settings menu.`

Or set it manually in the commandline with `date --set="2 OCT 2006 18:00:00”` to your current time.
{% endhint %}

To download new software packages, the Nvidia Board of the A1 has to be connected in the following way:

#### Networks other than ZHAW

1. Connect the nvidia board to the ethernet cable via the **ethernet to usb adapter** and `port 2 (TX2 USB3.0)` Check if your ethernet cable has a network connection.
2. Start the Unitree A1.
3. Connect Laptop to the Unitree Hotspot.
4. Connect over ssh in the windows powershell: `ssh unitree@192.168.123.12` (sometimes the bridge adapter to the Linux VM doesn’t work with the DNS of the LAN).
5. Enter the password `123`.
6. Check the internet connection with `ping google.com`. If you receive back data, the connection was successful.
7. Upgrade / install software.

#### @ ZHAW

To connect to the ZHAW network, additional changes have to be made:

1. Connect a monitor and keyboard using the HDMI (TX HDMI) and usb port (TX2 USB2.0).
2. Connect the nvidia board to the ethernet cable via the **ethernet to usb adapter** and `port 2 (TX2 USB3.0)`.
3. Start the robot.
4. Login using the password `123`.
5. Go to ***Settings/Network*** and find the correct `wired` network. The hardware address `00:13:3B:A3:00:6E` has full connection to the ZHAW network without having to log in. 
6. Check if the ***DNS*** is equal to `160.85.192.100 160.85.193.100`.
7. Access the ***options*** by pressing the `options` button.
8. In the ***Ethernet*** tab make sure the ***Device*** `eth1(00:13:3B:A3:00:6E)` is selected.
9. In the ***IPv4 Settings*** tab change the ***Method*** to `Automatic(DHCP)`, the ***DHCP client ID*** to `stud-pfammjur-1` and ***enable*** `Require IPv4 address for this connection to complete`.
10. Make sure to change these back to `Link-Local` for the LiDAR sensor.
11. You should now have access to the internet (if not, try turning WiFi off and on again or unplug the cable for a few seconds).
12. You can check the internet connection by opening a webpage via the chromium browser.
13. Upgrade / install software.
