Step 1: Diagnose Before You Fix
Blindly applying fixes wastes time. Before changing anything, run a ping test to establish a baseline and a speed test to check whether congestion is contributing. Then run a traceroute to the server you're having trouble with to see exactly where in the path latency accumulates.
Key questions to answer during diagnosis:
- Does the high ping occur on all servers, or just specific ones?
- Does it happen on wired and wireless connections, or just wireless?
- Is it constant or intermittent? Does it worsen during peak evening hours?
- Does running a speed test (which saturates your connection) spike your ping? If so, you likely have bufferbloat.
- Does your ping measure high only to distant servers (e.g., overseas), or also to servers in your own country?
Documenting these answers before starting saves significant troubleshooting time. If ping to a server in your own city is above 30–40 ms, there's definitely a local or ISP-level problem worth investigating.
Steps 2–4: Fix Your Local Network
2. Switch from WiFi to Ethernet. This is the single most impactful change for most users. WiFi adds 5–30 ms of latency under ideal conditions and significantly more when there's interference or congestion. A wired Ethernet connection eliminates wireless overhead, interference, and retransmissions.
3. Reboot your router and modem. Routers can develop routing table bloat, memory issues, and state table problems that accumulate over weeks. A full power cycle (unplug for 30 seconds, modem first, then router) often reduces latency by 10–30 ms on aging home equipment. Some gaming routers benefit from weekly reboots scheduled automatically.
4. Close background applications consuming bandwidth. Streaming updates (game clients, Windows Update, cloud backup), peer-to-peer applications, and streaming video can all cause queue buildup on your router. Use your router's traffic monitor or your OS task manager to identify bandwidth-hungry processes and pause them while gaming or on video calls.
On Windows, open Task Manager (Ctrl+Shift+Esc), click the Network column to sort by usage, and identify any processes consuming unexpected bandwidth. On macOS, use Activity Monitor and select the Network tab.

5. Enable QoS (Quality of Service). QoS allows your router to prioritize latency-sensitive traffic (gaming, VoIP) over bandwidth-heavy but tolerant traffic (downloads, backups). Most modern routers offer QoS under the WAN or Traffic Management settings. Some support "DSCP marking" which provides more granular control. Enabling QoS with gaming or VoIP priority often reduces in-game ping spikes by 30–60% when other devices are active on the network.
6. Fix bufferbloat by enabling SQM or CAKE. Bufferbloat is caused by oversized buffers in consumer routers that hold too many packets, causing massive latency spikes when the connection is saturated. If your router runs OpenWrt or DD-WRT, enable SQM (Smart Queue Management) with the CAKE algorithm — this typically reduces bufferbloat from 200+ ms spikes to under 10 ms. Even without custom firmware, reducing your QoS speed limits to 90–95% of your actual speeds can mitigate bufferbloat.
7. Use a 5 GHz WiFi band if you must stay wireless. The 5 GHz band is less congested, supports higher speeds, and typically delivers 5–15 ms lower latency than 2.4 GHz in environments with many WiFi networks. The tradeoff is shorter range. If you're near your router, 5 GHz (or 6 GHz on WiFi 6E routers) is almost always preferable for latency-sensitive applications.
Steps 8–10: ISP and Server-Side Fixes
8. Change your DNS servers. While DNS latency doesn't directly affect your ping to game servers, slow DNS resolution delays the initial connection and can cause intermittent "lag spikes" that are actually DNS timeouts. Switch to faster DNS resolvers — Google (8.8.8.8), Cloudflare (1.1.1.1), or your ISP's local DNS. You can test DNS performance to see which resolves fastest for your location.
9. Connect to a geographically closer server. Game clients and streaming services usually auto-select the nearest server, but they sometimes pick suboptimally. Manually selecting a server in your own country or region (rather than auto-select) can reduce latency by 50–150 ms for users on borders of auto-selection zones.
10. Contact your ISP with evidence. If traceroutes show high latency at ISP-owned hops (visible by the ASN in WHOIS data), document the issue with timestamped traceroute outputs and contact your ISP's technical support — not billing. Persistent high latency at the first few hops often indicates a line fault or degraded modem signal. Request a line quality test; they can check signal-to-noise ratio and error rates on your connection remotely.
Bonus: Advanced Techniques for Gamers
Beyond the core 10 steps, network-savvy gamers use several additional techniques:
- Dedicated gaming router — routers like the ASUS ROG Rapture or Netgear Nighthawk Pro include hardware-accelerated QoS and game-specific traffic classification that outperforms software solutions on consumer hardware.
- Gaming VPN for routing optimization — services like Exitlag or Mudfish offer multi-path routing that can sometimes find lower-latency paths to game servers by bypassing congested ISP peering points. Useful specifically when traceroute shows excessive hops through distant cities.
- Disable Nagle's algorithm on Windows — this TCP optimization batches small packets, which increases efficiency but also adds 5–40 ms of latency for games that use small frequent packets. Disable it in the Windows Registry for game-specific benefits.
- Monitor with mtr continuously — install MTR for Windows (WinMTR) and run it during gameplay sessions to capture transient spikes and identify their location precisely.
After applying changes, always re-run your ping test and speed test to measure the actual improvement before and after each fix.
Frequently Asked Questions
Why is my ping high only in the evening?
Evening peak hours (typically 7–11 PM) see the heaviest internet usage in residential areas. ISPs often have insufficient capacity at network aggregation and peering points, causing congestion and higher latency for all users. This is called 'peak hour congestion' and is an ISP infrastructure issue. Document it with timestamped ping tests and escalate to your ISP.
Does a gaming VPN actually lower ping?
Occasionally, yes — but usually no. Gaming VPNs help when your ISP routes traffic inefficiently and the VPN offers a more direct path. In most cases they add latency due to encryption overhead and routing through an extra server. Test your baseline ping first, then test with the VPN enabled to see whether it genuinely helps for your specific ISP and game server combination.
Can upgrading from 100 Mbps to 1 Gbps internet reduce my ping?
Not directly. Latency is mostly determined by routing and distance, not speed. However, if you were previously experiencing congestion on a 100 Mbps line (hitting your limit), upgrading eliminates that congestion source and may indirectly reduce latency. For most gamers, a stable 25 Mbps connection with 20 ms latency beats an unstable 1 Gbps connection with 80 ms latency.
What is a normal ping to a game server?
For servers in your own country or region, 10–50 ms is normal and excellent. 50–100 ms is acceptable. Servers on another continent will typically be 100–300 ms depending on the distance. For competitive gaming, anything above 80–100 ms to your primary game server region is worth investigating.
