Latency issues on a SA gaming PC usually come from Wi-Fi adding jitter, ISP peering routing traffic over congested undersea cables, Windows network adapter power-saving cutting the link briefly, or background upload traffic saturating your line's small upload budget. A seven-step sequence resolves most cases without an ISP call.
📡 Step 1-2: Wire up and test baseline
Plug directly into your router with Cat 6 Ethernet. Disable Wi-Fi on your PC. Open Command Prompt and run ping 8.8.8.8 -t for 60 seconds. Average should be 12-30ms; jitter (standard deviation) should be under 5ms; zero packet loss. If any of those fail, your home network is the problem. Check for cable damage, a cheap switch in the chain, or a router older than 5 years. Quality networking hardware on a gigabit fibre line typically hits 8-15ms to local resolvers.
🌐 Step 3-4: DNS and ISP route
Change DNS to Cloudflare (1.1.1.1 and 1.0.0.1) in Control Panel → Network → adapter properties → IPv4. Then tracert evetech.co.za and note the hop pattern: if hop 3-5 (your ISP gateway) already has 40ms, your line is congested. Try at different times of day. If only peak hour (5-9 PM) is bad, your ISP is oversubscribed on shared infrastructure. Switch to an ISP with less contention in your area, or escalate via your provider's support line.
Stage 4+ loadshedding causes fibre cabinets to lose battery and drop connections for hours after power returns. A UPS for your router and ONT keeps your side up, but you cannot fix the street-side cabinet. Expect elevated latency during SA power crises. {{/TipBox}}
🔋 Step 5: Disable NIC power saving
Device Manager → Network adapters → your Ethernet adapter → Properties → Power Management → untick "Allow the computer to turn off this device". Then on Advanced tab, set "Energy Efficient Ethernet" to Disabled, and "Green Ethernet" to Disabled. These features save 0.2W while costing 10-50ms spikes during idle periods. On competitive gaming PCs, these are always off.
📊 Step 6-7: Background traffic and QoS
Open Task Manager → Performance → Network and watch while "idle". If you see 1+ Mbps upload, something is syncing: OneDrive, Dropbox, Steam background downloads, Chrome tabs running video. Close them. In your router's admin panel, enable QoS and prioritise your gaming PC's MAC address. Pair with a fast gaming monitor and a low-latency wired mouse to remove the last few ms of perceived latency. Re-test ping after each step: you should see consistent 10-30ms to local servers and stable jitter under 5ms.
