Work From Home Internet Checklist

Your job went remote. Did your internet get the memo? Here is everything you need to check before your next meeting freezes at the worst possible moment.

Key Takeaway: Working from home reliably requires strong upload speed, not just download. With VPN overhead eating 10-30% of your bandwidth and multiple household members on calls, symmetrical fibre (where upload matches download) is the difference between smooth calls and pixelated frustration.

5 Key Points: Work From Home Internet Checklist

• Video calls on Zoom, Teams, and Meet need 3-5 Mbps upload per person. Add screen sharing and that jumps to 5-8 Mbps each way.
• Upload speed matters as much as download for remote work. Every camera feed, screen share, and cloud sync is outbound data.
• VPN encryption overhead costs you 10-30% of your raw speed. Factor this into your actual available bandwidth.
• A two-person WFH household with VPN and video calls needs roughly 15-20 Mbps upload running simultaneously during busy mornings.
• Symmetrical fibre packages give you equal upload and download, which can make remote work much smoother in busier households.

What Zoom, Teams, and Meet Actually Need

Working from home sounds great until you are three words into a client presentation and your face turns into a pixelated blob. Your boss asks you to repeat yourself. Your screen share lags. You spend the next ten minutes apologising for your connection instead of actually doing your job.

It is not your laptop. It is not the app. It is almost always your internet, specifically your upload speed and the total load your household is putting on the line.

Every video conferencing platform publishes recommended speeds, but most people never look them up. Here is what you are actually dealing with:

These numbers do not look scary on their own. Three or four megabits? Your fibre can do that in its sleep, right? Maybe. If you are the only person using it. But the moment you add screen sharing on top of video, you are pushing 5 Mbps upstream. Add a second person in the house on their own call, and that is 10 Mbps of upload, before anyone has even opened a browser, synced a file, or started a cloud backup running in the background.

Upload Speed: The Number Nobody Checks

Here is the part most people get wrong. When you shop for fibre, you look at the download speed, the big number. 50 Mbps. 100 Mbps. Looks great.

But for working from home, your upload speed matters just as much, sometimes more.

Every time your camera is on, you are uploading a live video stream. Every screen share, every file you push to the cloud, every message you send on Slack with an attachment: that is all upload. And most entry-level fibre packages give you significantly less upload than download.

A 50/25 package means you get 50 Mbps down but only 25 Mbps up. That sounds fine until two people in the house are on video calls while someone else is uploading a presentation to Google Drive. Suddenly that 25 Mbps is split three ways, and everyone’s video quality drops.

This is why symmetrical speeds, where your upload matches your download, make a real difference for remote workers. It is the difference between your colleagues seeing your face clearly and seeing a blurry mess that freezes every few seconds.

The VPN Tax Nobody Talks About

If your company uses a VPN (and most do for anything involving sensitive data), here is something you need to know: VPNs eat your bandwidth.

The encryption overhead typically costs you 10-30% of your raw speed. So that 25 Mbps upload? With a VPN running, you might be working with 17-22 Mbps in practice. It depends on the VPN provider, the encryption protocol, and how far away the server is, but the hit is real and it is consistent.

Now layer that on top of a video call running through the same VPN tunnel, and you are starting to feel the squeeze. Your IT department configured the VPN to route everything through the corporate network? That means even your Zoom traffic is taking the long way round, and your effective speeds drop further.

There is no way around this except having more speed to begin with. You cannot turn off the VPN. You cannot make the encryption lighter. The only variable you control is how much bandwidth you start with before the VPN takes its cut.

The Multi-WFH Household Problem

This is where it gets properly tricky, and it is increasingly common in South African homes. Two partners working remotely. Maybe a university student doing online lectures. Everyone needs reliable video calls, cloud access, and decent upload speed, all at the same time, all day.

Let us do the maths for a realistic two-person WFH household:

• Person 1: Video call with screen share = ~5 Mbps up, VPN overhead = ~30% extra
• Person 2: Video call with camera on = ~4 Mbps up, VPN overhead = ~30% extra
• Background sync: Cloud storage, email, messaging apps = ~2-3 Mbps up
• Other devices: Phones, smart home gear, security cameras = ~2-5 Mbps

That is roughly 15-20 Mbps of upload running simultaneously during a busy morning. On a package with 25 Mbps upload, you are already at 60-80% capacity, and that is before anyone downloads anything or a system update kicks off.

Now add a third person. A teenager in an online lecture with their camera on, or a housemate doing freelance work on video calls. Your 25 Mbps upload is done. Calls start dropping quality, screen shares stutter, and someone ends up turning their camera off just to keep the audio working.

The solution is not telling everyone to schedule their calls at different times. The solution is having enough bandwidth that nobody has to think about it.

The Checklist

Before your next work week, run through this:

Check your upload speed, not just download. Run a speed test at speedtest.net and look at the upload number specifically.

Count the simultaneous users. How many people in your home are on calls or uploading at the same time during work hours?

Factor in VPN overhead. Knock 20-30% off your measured upload speed if you use a corporate VPN.

Check your router placement. Your home office should have strong Wi-Fi signal, or better yet, a wired ethernet connection.

Monitor peak usage. If your calls are worst between 9AM and 12PM, that is your household peaking, not the network.

If the numbers do not add up, your package is not sized for how your household actually works.

Frequently Asked Questions

How much upload speed do I need to work from home? For a single person on regular video calls with screen sharing, you need at least 10 Mbps upload after VPN overhead. For two people working from home simultaneously, aim for 25 Mbps upload minimum. Symmetrical packages like Infini-fi 100/100 or 200/200 are ideal.

Why do my video calls freeze even though my internet seems fast? You are probably looking at your download speed. Video calls depend heavily on upload speed. Run a speed test and check your upload number. If it is below 5 Mbps while other people in the house are online, that is likely your bottleneck.

Does a VPN really slow down my internet by 10-30%? Yes. VPN encryption adds overhead to every packet of data. The exact impact depends on your VPN provider, the encryption protocol, and the server distance, but 10-30% speed reduction is typical. This is why starting with higher base speeds matters for WFH.

Is 25 Mbps upload enough for two people working from home? It can work, but you will be operating at 60-80% capacity during busy periods with limited headroom. If both people are on video calls with screen sharing plus VPN, quality may drop. A 50 Mbps or 100 Mbps symmetrical upload gives proper breathing room.

What is the difference between symmetrical and asymmetrical fibre? Asymmetrical packages give you more download than upload (e.g. 50/25 Mbps). Symmetrical packages give you equal speeds in both directions (e.g. 100/100 Mbps). For work from home, symmetrical is better because video calls, screen sharing, and cloud sync all depend on upload speed.

A Practical Starting Point

As a general guide, a single remote worker can often manage on a moderate fibre line if the household is quiet during the day. Where work-from-home setups usually struggle is shared use: multiple calls, cloud syncing, VPN overhead, and other family activity happening at the same time.

If you are comparing options, focus on upload performance and stability as much as download speed, then use our deals page to match that to the current package range.
