Most people need at least 25Mbps to work from home. You can enjoy 720p HD video conferencing on Zoom using only 2.6Mbps of uploading bandwidth and 1.8Mbps of downloading bandwidth.
The higher speeds these ISPs provide really come in handy when downloading or uploading large files. If a coworker sends you a video recording they'd like to get your feedback on, you may have to wait several minutes for it to download if your speeds are significantly lower than what these ISPs offer. That's why it's best to aim for 200Mbps or higher if you want to work from home.
