How to Reduce WiFi Latency for Gaming and Video Calls

Latency — the time it takes data to travel from your device to a server and back — is the difference between a buttery-smooth gaming session and a frustrating lag fest. While download speed gets all the attention, latency (measured in milliseconds of “ping”) is what gamers and video callers actually feel. The good news: most WiFi latency problems are fixable without buying new hardware.

What Is a Good Latency for Gaming and Video Calls?

Not all latency is created equal. Here’s how to grade your ping:

• 0–30 ms: Excellent. Virtually lag-free, ideal for competitive gaming (CS2, Call of Duty, Valorant).
• 31–50 ms: Good. Most players notice no delay at all.
• 51–100 ms: Playable. Fine for casual gaming; not recommended for fast-paced competitive titles.
• 101–150 ms: Borderline. Noticeable lag; reaction times suffer.
• 150 ms+: Poor. Significant, game-breaking delay.

For video calls (Zoom, Teams, Google Meet), conversations feel natural under 150 ms round-trip time. Above 300 ms, people start accidentally talking over each other. Jitter (variation in latency) should stay under 40 ms, and packet loss under 2% for clean audio and video.

What Causes High WiFi Latency?

Before diving into fixes, it helps to know what you’re fighting:

• Bufferbloat: When your router’s buffer fills up during heavy downloads or uploads, all other traffic — including your game packets — gets stuck behind it. This creates the dreaded “lag spikes when someone downloads something” pattern and is the most underappreciated cause of gaming latency.
• Channel congestion: In apartments and dense neighborhoods, dozens of WiFi networks share the same channels, forcing devices to queue for airtime.
• Wrong frequency band: The 2.4 GHz band adds far more latency than 5 GHz. In real-world tests, 2.4 GHz averages around 12.9 ms with spikes up to 52 ms, while 5 GHz averages just 4.6 ms with much lower jitter.
• Physical obstacles: Every wall, floor, or metal object between your device and router forces packet retransmissions that add latency.
• Too many devices: Bandwidth contention increases with every connected device, adding queueing delays.

8 Ways to Reduce WiFi Latency

1. Use a Wired Ethernet Connection

This is the single biggest improvement you can make. Ethernet eliminates WiFi overhead entirely, typically cutting latency by 15–25 ms and reducing jitter to near zero. A Cat5e or Cat6 cable connected directly from your PC or console to the router is the gold standard for gaming and video calls. If running cable isn’t practical, see our guide on how to run Ethernet cable through walls.

2. Switch to the 5 GHz Band

If you’re on 2.4 GHz WiFi, switching to 5 GHz alone can cut your wireless latency by two-thirds and dramatically reduce jitter. Log into your router or phone settings and connect to the 5 GHz version of your network (often labeled with a “5G” suffix). The 5 GHz band has far less interference from neighboring networks, microwaves, and Bluetooth devices. The tradeoff is shorter range, so this works best when you’re within 30–40 feet of the router.

3. Fix Bufferbloat with SQM or QoS

Bufferbloat is the hidden killer of gaming and VoIP performance. The most effective fix is Smart Queue Management (SQM) using the fq_codel or CAKE algorithm, available in router firmware like OpenWrt, ASUS Merlin, pfSense, OPNsense, and on GL.iNet routers. SQM can reduce bufferbloat-induced latency by 90–99% compared to a router with no queue management.

If your router doesn’t support SQM, enable standard QoS (Quality of Service) and set your gaming device or console to highest priority. Set the QoS upload bandwidth to about 85–90% of your measured upstream speed (not the advertised rate) to prevent line saturation. See our dedicated guide on how to fix bufferbloat for a step-by-step walkthrough.

4. Select a Less Congested WiFi Channel

On the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping — always use one of these three. Download a free WiFi analyzer app and find which of those three channels has the fewest competing networks at the strongest signal levels. On 5 GHz, channels 36, 40, 44, and 48 (the lower UNII-1 band) are typically the least congested and don’t require DFS radar avoidance delays. Log into your router admin panel (usually 192.168.1.1) to make the change manually.

5. Optimize Router Placement

Your router’s physical position directly affects signal quality, and weak signals cause retransmissions that add latency. Place the router in a central, elevated location — on a shelf or table in the middle of your home. Keep it away from microwaves, cordless phones, metal appliances, and concrete walls. For gaming rooms far from the router, a WiFi range extender or a second access point connected via Ethernet can bring the router signal closer to your device.

6. Reduce Network Load During Gaming Sessions

Pause large downloads, cloud backups (iCloud, Google Drive, OneDrive), and streaming on other devices while gaming or on a video call. Even a single device running a Windows update in the background can saturate upload bandwidth and trigger bufferbloat that spikes your ping from 20 ms to 200 ms. This is especially true for upload — most broadband connections have asymmetric speeds with much less upstream bandwidth available.

7. Restart Your Router Regularly

Routers accumulate memory leaks, stale NAT table entries, and fragmented buffers over weeks of continuous operation. A quick reboot (unplug for 30 seconds) clears all of this and can restore optimal routing performance. Many gamers schedule a weekly router reboot and see consistent latency improvements. Consider a smart plug on a schedule if you want this automated.

8. Upgrade to WiFi 6 for Dense Environments

If you’ve tried the above fixes and still see high latency in a busy household or apartment building, the problem may be your router’s inability to handle traffic efficiently. WiFi 6 (802.11ax) introduced OFDMA (which serves multiple devices simultaneously instead of one at a time) and BSS Coloring (which reduces interference from neighboring networks). In congested environments, real-world testing shows WiFi 6 can reduce average latency from 42 ms to 11 ms during peak hours — a 75% improvement. See our guide on whether upgrading to WiFi 6 is worth it for a full breakdown.

Quick Diagnosis: Run a Speed Test Under Load

The fastest way to determine if bufferbloat is your culprit: run a speed test once normally, then run it again while simultaneously downloading a large file. If your ping spikes dramatically during the loaded test (e.g., from 20 ms to 200+ ms), bufferbloat is your primary problem and SQM or QoS should be your first fix.

If ping is high even without load, the issue is more likely distance from the router, wrong WiFi band, or ISP-side congestion — which no home router setting can fix. In that case, an Ethernet cable or a closer access point is the answer.

Summary: Priority Order for Reducing WiFi Latency

1. Use Ethernet if at all possible
2. Switch from 2.4 GHz to 5 GHz WiFi
3. Enable SQM or QoS on your router
4. Select a less congested WiFi channel
5. Optimize router placement (closer, more central)
6. Pause downloads and backups during play
7. Reboot your router weekly
8. Upgrade to WiFi 6 if the above steps aren’t enough
