Is 4 Mbps Fast Enough to Work From Home?

Working from home requires that you have a secure, and stable connection, especially if you want to work effectively. 4 mbps internet is a little slow if you are planning on working from home.

We really recommend at least an internet speed of 5 mbps if you are planning on working from home. With an internet speed of 4 mbps, you should be able to browse the web, open and send emails, use zoom, as well as download moderate sized files in a timely manner.

If your job requires the sending and receiving of very large files (over 100 mbps or more) then your work efficiency may suffer as it will take you a long time to send and receive files with such a slow internet speed.

If downloading and uploading will be most important for your work, then we highly recommend going with a higher internet speed like 25 mbps. This speed is about 5 times faster than 4 mbps and should also give you about a 5 mbps upload minimum to go along with it.


Zoom is one of the main reasons to have a fast and reliable internet speed. Zoom is mostly used for internet voice calls as well as video calls/chats. This is a must have application if you are working from home as it’s a great way to keep in touch with your boss as well as coworkers.

In order to meet the minimum requirements set by Zoom themselves, you will need to have at least 3.8 mbps down as well as at least a 3mbps upload. This is essential to stream 1 on 1 video and group calls in 1080p quality.

Having a download speed of 4 mbps is barely meeting this minimum, so you may have a lower quality stream than the 1080p, but nonetheless, you will still be able to use Zoom just fine.
