What a home office connection actually needs: video calls, VPN overhead, cloud tools, and how to stay reliable when the rest of the household is online too.

Remote work isn't one thing, bandwidth-wise
A home office connection has to handle several different kinds of traffic at once : video calls that need steady upload and low latency, cloud apps that sync in the background, occasional large file uploads, and sometimes a VPN layered on top of all of it. None of these individually need a huge amount of bandwidth, but they're sensitive to different things: calls care about latency and jitter, uploads care about raw upload speed, and everything gets worse at once if the connection is also congested.
Video calls and screen sharing
Video calls are usually the most noticeable part of a remote workday, and they lean on upload as much as download : your camera and microphone feed has to go out at the same time everyone else's comes in. Screen sharing adds its own overhead on top. See our video calls guide for typical bandwidth numbers and why latency and jitter matter more than a big download figure here.
VPN overhead
A work VPN routes your traffic through an extra server and encrypts it, which adds latency and can cap your effective throughput below what your connection is otherwise capable of. A noticeably slower speed test result with the VPN on than off is expected behavior, not a fault with your home connection : if it's a significant drag on your workday, ask whether your organization's VPN supports split-tunneling so only work traffic actually needs to go through it.
Cloud tools and background sync
Cloud storage and collaboration tools (file sync, automatic backups, large attachments) quietly use upload bandwidth in the background, often without you noticing until a call starts stuttering right as a big file finishes uploading. If calls degrade at predictable moments during the day, check what's syncing at that time before assuming the connection itself is the problem.
Sharing a connection with the rest of the household
Working from home usually means sharing bandwidth with everyone else at home during the day too : a partner streaming, kids on remote schooling, or general household devices. None of that needs to be a problem if the connection has enough headroom for your busiest realistic moment, not just your average one. Use the calculator on What Is a Good Internet Speed? to add up what's actually running at the same time in your home.
When it's bufferbloat, not bandwidth
A connection with plenty of raw speed can still make calls stutter the moment someone else starts a large download or upload : that's loaded latency (bufferbloat), not a lack of bandwidth. See ping, jitter & loaded latency explained for how to read that signal, and consider enabling Quality of Service (QoS) on your router if it's available, since it can prioritize call traffic ahead of large transfers sharing the same line.
Wi-Fi vs. a wired desk setup
If your desk is in a fixed spot and video calls or uploads are a daily part of the job, a wired Ethernet connection removes Wi-Fi signal strength, interference, and contention from the equation entirely. See Wi-Fi vs. Ethernet for when the effort of running a cable is worth it.
Frequently asked questions
For video calls, cloud apps, and general office work, 25-50 Mbps download and at least 5-10 Mbps upload is comfortable for one person. The bigger factor is usually who else is sharing the connection during the day, not the raw number.
Yes, to some degree : a VPN adds an extra hop and encryption overhead, which increases latency and can cap throughput below what you'd get without it. A large drop when the VPN is on is normal; see if your IT team offers split-tunneling for non-work traffic.
You're likely sharing limited bandwidth or hitting bufferbloat : the other stream is saturating the connection and delaying your call's small, time-sensitive packets. Check loaded latency specifically, and consider enabling QoS on your router if it supports it.
Wi-Fi is fine for most remote work, but if your desk is fixed and you rely on video calls or large uploads daily, a wired connection removes Wi-Fi as a variable entirely and is usually worth the one-time effort of running a cable.

Check your home office connection
Run a speed test during a normal workday : ideally with your VPN on and other household devices active : to see what your connection actually delivers under real conditions, not just its best case.
