It depends on what type of work you do and the number of people teleworking or online at the same time.
If you regularly download and upload large files and take part in videoconferences, a minimum download speed of 25 Mbps is recommended if you’re the only person working from home.
Here are some examples of minimum recommended speeds* for different types of telework:
Google Hangouts : 2.6 to 4 Mbps
Microsoft Teams : 1 to 4 Mbps
Skype : 0.2 to 4 Mbps
Zoom : 0.6 to 4 Mbps
Email : 1 Mbps
Web browsing : 3 to 5 Mbps
Social media: : 3 to 10 Mbps
