Connecting your OT-2 to Wi-Fi offers an improved experience using your robot and the Opentrons App:

  • You can run your protocols from anywhere you can connect to the same network
  • Our Support Team is better able to diagnose and fix any problems you may encounter

We recommend reading our Networking Requirements for the OT-2 support article first to make sure your networking environment is properly set-up. Also, please ensure you are running the latest version of the Opentrons App and your robot is fully up-to-date before proceeding.

We highly recommend that you only change the Wi-Fi network of your robot while connected via USB-to-Ethernet. Changing the Wi-Fi network of a robot while you are connected over Wi-Fi can prevent the app from communicating with the robot, because you could move the robot to a network your computer is not connected to.

Connecting to a WPA2 Personal network

WPA2 Personal is a standard Wi-Fi network that requires a password. To connect to a WPA2 Personal network:

  1. Select the network in the list
  2. Enter your password
  3. Click “Join” or press “Enter/Return” on your keyboard
  4. The robot will attempt to join to the selected network

Connecting to a WPA2 Enterprise network

A WPA2 Enterprise network (also known as 802.1x and “eduroam”) is a Wi-Fi network with extra authentication mechanisms for extra security. We support the following security types, which require the following credentials. Please contact your IT department if you are unsure of the credentials per your institution's EAP:

EAP-TTLS with TLS (ttls/eap-tls)

  • Username (required)
  • Anonymous Identity (optional)
  • CA Certificate File (optional)
  • Private Key File (optional)
  • Private Key Password (optional)
  • Inner Client Certificate File (required)
  • Inner Private Key File (required)
  • Inner Private Key Password (optional)
  • Inner CA Certificate File (optional)

EAP-TTLS with MS-CHAP v2 (ttls/eap-mschapv2)

  • Username (required)
  • Password (required)
  • Anonymous Identity (optional)
  • CA Certificate File (optional)
  • Client Certificate File (optional)
  • Private Key File (optional)
  • Private Key Password (optional)

EAP-TTLS with MD5 (ttls/eap-md5)

  • Username (required)
  • Password (required)
  • Anonymous Identity (optional)
  • CA Certificate File (optional)
  • Client Certificate File (optional)
  • Private Key File (optional)
  • Private Key Password (optional)

EAP-PEAP with MS-CHAP v2 (peap/eap-mschapv2)

  • Username (required)
  • Password (required)
  • Anonymous Identity (optional)
  • CA Certificate File (optional)

EAP-TLS (tls)

  • Username (required)
  • Client Certificate File (required)
  • Private Key File (required)
  • Private Key Password (optional)
  • CA Certificate File (optional)

To connect to a WPA2 Enterprise network:

  1. Select the network in the list
  2. Enter your credentials
  3. For text credentials like “Username”, type them in
  4. For password credentials like “Password”, type them in and toggle the “Show Password” checkbox if you would like to double-check them
  5. For file credentials like “Client Certificate File”, either:
  6. Select a previously uploaded certificate from the list, or
  7. Select “Add new…” to upload a new file
  8. Click “Join” or press “Enter/Return” on your keyboard
  9. The robot will attempt to join to the selected network

Connecting to an open Wi-Fi network

The OT-2 supports connecting to Wi-Fi networks without any security. We do not recommend connecting your robot to unsecured networks, because anybody could then connect to the network and control your robot. Also, please note that the OT-2 does not support networks that use a captive-portal.

If you are aware of the risk and would still like to connect to an open network:

  1. Select the network in the list
  2. The robot will attempt to join the selected network

Troubleshooting

If you can’t connect to a Wi-Fi network, we recommend the following steps:

  1. Make sure your app and robot are fully up-to-date
  2. If you are connecting to an open network, please make sure the network does not use a captive portal
  3. The OT-2 does not support captive portal networks
  4. Double check your network credentials
  5. The “Show Password” toggle can be useful to ensure you are typing any passwords in correctly
  6. If you are having trouble connecting to a WPA2 Enterprise network, please consult your IT department
  7. Your IT department will know more than us about your particular network setup and credentials
  8. They may need to whitelist your robot’s MAC address or something similar
  9. If you’re still unable to connect, connect our Support Team with the error message(s) you are receiving along with any details from your IT department (if applicable)

If you are able to connect your OT-2  to Wi-Fi but your app is unable to find your robot on your Wi-Fi network, please ensure that your network and firewall(s) are set up to allow traffic as described in the “Networking Requirements for OT-2” support document. If you are on an enterprise network, you may want to check in with your IT department.
