Technical Requirements

Browser, device, and network requirements for Lingco Classroom, including the domains and email addresses to whitelist.

Written by Ryan Graffy

Lingco is a modern web-based application. It runs in the browser, with nothing to install.

Supported browsers

  • Google Chrome — latest version. Recommended.

  • Safari — latest two versions

  • Mozilla Firefox — latest two versions

  • Microsoft Edge — latest two versions

Supported devices

  • Laptop or desktop computer — Windows, Mac, or Chromebook. Recommended.

  • iPad — fully supported

What you'll need

  • A stable internet connection with at least 4 Mbps download and 512 Kbps upload speeds

  • A screen size of at least 1280x720 pixels

  • Functioning speakers or headphones

  • A microphone, if your course includes speaking or pronunciation activities. A built-in mic works, but a headset gives much better results in a classroom.

  • A webcam, if your course includes video recording prompts

Note: Certain school network components, such as VPNs and firewalls, can impact the quality of audio and video files in Lingco. Please discuss this with your IT department if you discover such issues.

Domains and emails to whitelist

Course videos, audio, and images load from Lingco domains, and our account email is sent from them as well. If your school filters web or email traffic, IT will need to allow both.

Make sure email from lingco.io reaches instructors and students. It's sent from:

Whitelist both of these URLs:

  • lingco.io

  • *.lingco.io

The asterisk before .lingco.io is very important, since it accounts for any variation, such as class.lingco.io.

Checking a device

To confirm a specific computer is ready, open https://class.lingco.io/tech_check on it. No sign-in is needed. The page checks the browser, screen, network, speakers, microphone, and webcam, and tells you which one is failing.

Still having trouble? Email us at [email protected] and include what the tech check reported.
