Quick Answer
For school-holiday gaming with the whole house online, a dual-band Wi-Fi 6 router with QoS is the must-have. A TP-Link Archer AX55 (around R2,200) handles 20-30 devices and lets you prioritise the gaming PC so a sibling's stream does not spike your ping past 60ms.
Must-have, nice-to-have, skip
Must-have: Wi-Fi 6 and Quality of Service (QoS). Holidays mean every device is on at once, so QoS that prioritises the gaming PC keeps online matches under 40ms even while others stream. The Archer AX55 or ASUS RT-AX58U handle a busy household for around R2,200-R2,800. Nice-to-have: a mesh node if bedrooms sit far from the lounge, and a 160MHz channel for faster local transfers. Skip: tri-band flagships over R6,000 for a single-line home; the extra band rarely helps when the fibre cap is the real ceiling.
Sharing one line without ping spikes
When five people share a 100-200Mbps line over a holiday, congestion, not router speed, ruins gaming. Enable QoS and tag the gaming PC as highest priority so background downloads and 4K streams yield bandwidth during a match. A wired connection to the main gaming machine takes it out of the Wi-Fi contest entirely. If coverage is the issue rather than congestion, a Wi-Fi 6 mesh kit (TP-Link Deco X50 2-pack around R3,800) spreads signal to far bedrooms without dead zones that cause rubber-banding.
FAQ
How many devices can a home router handle during holidays?
A decent Wi-Fi 6 router like the Archer AX55 comfortably manages 20-30 active devices. The limit you hit first is usually the fibre line's bandwidth, not the router, so enable QoS to share it fairly.
Will QoS really lower my gaming ping?
Yes, when the line is congested. QoS tells the router to serve the gaming PC first, so a sibling's download or stream no longer spikes your ping. On an idle line it makes no difference, but holidays are rarely idle.
Do I need a wired connection for the gaming PC?
It is the most reliable fix. A wired PC sidesteps Wi-Fi congestion entirely, holding steady ping while phones and TVs share the wireless band. If you can run one cable, run it to the gaming machine.
QoS before the holidays", body="In your router app, enable QoS and set the gaming PC as top priority. It takes two minutes and is the difference between smooth matches and ping spikes every time someone else starts a download."
