How to Share Internet With a Housemate While WFH in SA

Quick Answer

Sharing internet with a housemate while working from home in South Africa works best by connecting both devices to the same router or Wi-Fi network and managing bandwidth through QoS settings. For heavy users, a Wi-Fi 6 router or a dedicated second line is the most reliable long-term solution.

Sharing a fibre or LTE connection with a housemate while both of you work from home is a balancing act. South African fibre plans have improved significantly in value, but a single 50Mbps or 100Mbps line shared between two people on video calls, large file uploads, and cloud applications can still feel constrained. Here are the practical approaches that actually work.

Set Up QoS on Your Router

Quality of Service (QoS) is the first tool to use. Most mid-range and premium routers - including those bundled by SA ISPs or purchased separately - have a QoS settings page in the admin panel (usually accessed at 192.168.1.1 or 192.168.0.1 in your browser). QoS lets you prioritize traffic by device, application type, or time of day. Set video conferencing apps (Zoom, Teams, Google Meet) as high priority for both devices, and deprioritize large downloads or streaming during core work hours. This alone can prevent one housemate's 2GB software update from breaking the other's Zoom call.

Wired vs Wireless: Which Housemate Gets the Cable?

If only one Ethernet port is available near the router, give the cable to whoever has the most latency-sensitive workload. Video calls and VoIP (like Microsoft Teams calls) are more sensitive to jitter and packet loss than general web browsing or document work. A wired connection eliminates Wi-Fi interference and provides consistent speeds. The other housemate benefits from a good Wi-Fi 5 or Wi-Fi 6 router. If your rental's router is a basic ISP-provided unit, replacing it with a quality router (R800 to R2,000 in SA) is one of the best WFH investments you can make.

When to Consider a Second Line

If both housemates are constantly on video calls, uploading large files, or running cloud-heavy workflows, a second line is worth considering. Many South African fibre providers offer entry-level plans at R350 to R600 per month. Splitting this cost between two people is less than the productivity loss from a congested shared line. Alternatively, one person can use a mobile LTE or 5G connection as a backup for high-priority calls, while the shared fibre line handles everything else.

Frequently Asked Questions

Q: Can two people use the same Wi-Fi network for remote work without issues? A: On a 50Mbps or faster fibre line, yes - most of the time. Video calls use 1.5Mbps to 4Mbps per person, so bandwidth isn't usually the issue. Congestion problems are more often caused by large background downloads or a weak Wi-Fi signal than raw speed.

Q: What is the best router for a shared WFH setup in South Africa? A: A Wi-Fi 6 router with QoS controls makes a meaningful difference in shared environments. Look for units with dual-band or tri-band support to separate high-demand devices onto less congested frequencies.

Q: Is using a mobile hotspot as a backup a good idea during loadshedding? A: Yes. If your fibre router loses power during loadshedding, a mobile hotspot from your phone's cellular data keeps critical calls running. Most SA mobile plans have enough data for a few hours of video calls per month.
