Internet Speed for Working From Home
Working from home is more demanding on your upload speed than your download speed. A 500 Mbps download / 10 Mbps upload connection performs worse for remote work than a 50 Mbps symmetric connection. Here's what you actually need.
Speed requirements by WFH role
| Role / activity | Min download | Min upload | Latency target |
|---|---|---|---|
| Email, documents, light browsing | 5 Mbps | 2 Mbps | Any |
| 1-on-1 HD video call (Zoom, Teams) | 2.5 Mbps | 2.5 Mbps | <100 ms |
| Group video call (5+ participants) | 4 Mbps | 3.8 Mbps | <80 ms |
| Screen sharing (high resolution) | 2 Mbps | 4 Mbps | <80 ms |
| Cloud storage sync (Google Drive, OneDrive) | 2 Mbps | 10–50 Mbps | Any |
| Corporate VPN (light use) | 10 Mbps | 5 Mbps | <60 ms to VPN server |
| Video editing / large file transfers | 50 Mbps | 50 Mbps | Any |
| Developer / CI pipelines, large repo pushes | 25 Mbps | 25 Mbps | Any |
The hidden cost: cloud backup running in the background
Most WFH setups have automatic cloud backup running continuously - ICloud, OneDrive, Google Drive, Dropbox, or a corporate backup agent. These silently consume your upload bandwidth throughout the day. A cloud backup pushing 5 Mbps of files in the background is enough to degrade a video call on a connection with only 10 Mbps upload.
Solutions:
- Schedule cloud backups outside working hours (6 PM–8 AM)
- Enable bandwidth throttling in the backup client settings
- Enable QoS on your router to prioritise video call traffic over backup traffic
Multi-person households - Planning for simultaneous use
| Scenario | Download needed | Upload needed |
|---|---|---|
| 1 person WFH + 1 person streaming HD | 20 Mbps | 10 Mbps |
| 2 people WFH (both on video calls) | 20 Mbps | 20 Mbps |
| 2 WFH + 2 children remote schooling | 30 Mbps | 30 Mbps |
| 2 WFH + 4K TV + gaming + backups | 75 Mbps | 50 Mbps |
Why you should use Ethernet at your desk
Video calls are sensitive to jitter - The variation in latency over time. Wi-Fi introduces jitter due to channel contention, interference, and retransmissions. On a busy household Wi-Fi, jitter of 15–30 ms is common. This causes your video and audio to freeze and stutter on calls, even when average bandwidth is sufficient.
Ethernet eliminates Wi-Fi jitter entirely. For a home worker, connecting your laptop or desktop to the router via Ethernet cable is the single most impactful change you can make. Jitter drops to under 1 ms; audio quality becomes consistently clear. Ethernet vs Wi-Fi - The data →
Corporate VPN and your home connection
Many employers require staff to use a corporate VPN. This adds two costs: the encryption/decryption overhead (typically 10–20% speed reduction) and the additional latency to the VPN server (10–80 ms depending on location). If your corporate VPN server is in a distant data centre, all traffic - Including video calls - Is routed through it, adding round-trip latency to every packet.
The best mitigation: ask your IT team whether split tunnelling is available. Split tunnelling routes work traffic through the VPN while allowing direct internet access (Zoom, Slack, YouTube) to bypass the VPN entirely, dramatically improving call quality. How VPNs affect speed →
Checklist for an optimised WFH connection
- Connect your work computer to Ethernet, not Wi-Fi
- Schedule cloud backups for outside working hours
- Enable QoS on your router for video call traffic prioritisation
- Use a plan with at least 20 Mbps symmetric upload if multiple people work from home
- Keep your router firmware updated - Older firmware can have buffer management issues
- Test your connection at the start of a working day - Not just once a week
Frequently Asked Questions
Will a faster download plan improve my remote work if my upload stays the same?
Usually not. Most remote work bottlenecks, such as pixelated call video and slow cloud sync, are limited by upload, which many ISPs cap far below the advertised download. A symmetric fibre plan with balanced upload often improves your day more than a higher download tier on the same asymmetric service.
How can I tell if a cloud backup is what is ruining my calls?
Pause your backup client (iCloud, OneDrive, Dropbox, or a corporate agent) and run a call or upload test immediately afterward. If quality improves noticeably, the backup was saturating your upload. You can then schedule it outside working hours or enable bandwidth throttling in its settings.
Does QoS on my router actually help with working from home?
Yes, when several devices share one connection. QoS lets you prioritise real-time video call traffic over bulk transfers like backups and downloads, so your call stays smooth when the household is busy. It does not add bandwidth, but it decides what gets served first when the link is full.
Should I ask my employer about split tunnelling for the VPN?
It is worth asking if calls degrade whenever the corporate VPN is connected. Routing every packet through a distant VPN server adds latency and encryption overhead to Zoom, Teams, and Slack. Split tunnelling lets that traffic reach the internet directly while keeping work systems on the VPN, which usually restores call quality.
