How to reduce ping on a Wi-Fi router: from simple settings to hardware upgrades

Have you noticed that in online games, characters seem to "teleport" or that in Zoom or Discord, the voice of the person you're talking to cuts out with a delay? The culprit is a high ping (network response delay), and most often the problem lies in your Wi-Fi router settings. Even with a stable internet connection from your provider, an incorrectly selected channel, an overloaded network, or outdated firmware can add extra milliseconds to each data packet.

In this article we will look at specific reasons high ping on routers of popular brands (TP-Link, ASUS, Keenetic, MikroTik) and provide step-by-step instructions on how to fix them—from changing the Wi-Fi channel to upgrading your network hardware. All recommendations have been tested on current router models (2023–2026) and require no specialized knowledge. If you're ready to reduce latency to an acceptable level (ideally— less than 30 ms for games and less than 100 ms for video communication), read on.

1. Check your current ping and identify the bottleneck

Before optimizing your router, make sure it's the problem. High ping can be caused by:

• 🌍 Provider — check the ping directly by connecting the cable to the PC (bypassing Wi-Fi).
• 📡 Router — if the ping is low via cable and high via Wi-Fi, the wireless network is to blame.
• 💻 Devices - Old laptops or smartphones may not support modern Wi-Fi standards (802.11ac/ax).

For testing, use the commands in Command line (Windows) or Terminal (macOS/Linux):

ping -n 20 ya.ru

Or use online services like Speedtest (Ping tab). If the difference between the cable and Wi-Fi ping exceeds 20–30 ms, the problem is definitely in the router settings.

2. Change your Wi-Fi channel: how to avoid interference from neighbors

The most common reason for high ping is congested channels in the 2.4 GHz band. In apartment buildings, neighbors' routers may use the same channel, causing interference. The solution is to manually select the least congested channel.

To do this:

1. Download the network analysis utility: Wi-Fi Analyzer (Android), NetSpot (Windows/macOS) or inSSIDer.
2. Check which channels are free (it’s better to choose 2.4 GHz) 1, 6 or 11 - they do not intersect).
3. Go to your router settings (usually at 192.168.1.1 or 192.168.0.1) and change the channel in the section Wireless Settings.

For 5 GHz, the situation is different: there are more channels and they are less susceptible to interference. It is optimal to choose channels with 36 By 48 (DFC channels may require additional settings in some countries).

⚠️ Attention: In some routers (Keenetic, Zyxel) when changing the channel in 5 GHz, you may need to specify Country Code (country code) in the settings, otherwise some channels will be unavailable.

3. Configure QoS (Quality of Service) to prioritize traffic

QoS Quality of Service (QoS) allows the router to distribute traffic so that critical packets (such as those from online games or video calls) pass through without delay. Without QoS, the router processes all data equally—from torrent downloads to Discord voice calls.

How to configure QoS on popular routers:

If your router does not support QoS, an alternative is to limit the speed for bandwidth-hungry devices (such as torrent clients) manually via Bandwidth Control.

4. Update your router firmware and disable unnecessary features

Outdated firmware may contain bugs that increase latency. Manufacturers regularly release updates that optimize packet processing. Check the firmware update in the router's web interface (section System Tools or Administration).

Also disable features that may slow down the network:

• 🔄 IPv6 - If your provider does not support it, disable it. Network → IPv6.
• 📡 Guest network - it takes up the router's resources even if it is not used.
• 🔒 Parental control — traffic filtering adds delay.
• 📊 Traffic statistics — data collection may put a strain on the processor.

⚠️ Attention: On routers MikroTik disabling the function FastTrack (V IP → Firewall → NAT) may increase ping. Leave it enabled unless you use complex firewall rules.

5. Optimize DNS and MTU settings

DNS servers ISPs may be slow, increasing response times. Replace them with public ones:

• 🌐 1.1.1.1 (Cloudflare) - Low latency, high speed.
• 🌐 8.8.8.8 (Google DNS) - stable, but sometimes overloaded.
• 🌐 76.76.76.76 (Yandex DNS) — optimized for Russia.

You can change DNS in the router settings (Network → WAN) or on the device itself.

MTU (Maximum Transmission Unit) — the maximum data packet size. If the value is too large, packets are fragmented, which increases ping. The optimal value for most networks is 1472 (for PPPoE) or 1500 (for DHCP). Change it in WAN Settings and check the ping after rebooting the router.

ping -f -l 1472 ya.ru

6. Change the Wi-Fi standard and channel width

Old standards (802.11n) and narrow channels limit speed and increase latency. Switch to modern ones:

• 📶 2.4 GHz — select standard 802.11n and channel width 20 MHz (wider - more interference).
• 📶 5 GHz - use 802.11ac or 802.11ax (Wi-Fi 6) with channel width 40 MHz or 80 MHz.

On routers with support Wi-Fi 6 (ASUS RT-AX88U, TP-Link Archer AX6000) enable features OFDMA And TWT - They reduce latency by distributing traffic more efficiently.

If your device does not support Wi-Fi 6, but the router—yes, don't disable this mode completely. Instead, in the wireless network settings (Wireless Mode) select 802.11a/n/ac/ax for backward compatibility.

7. Hardware upgrades: when software methods don't help

If all settings are optimized, but the ping remains high, the problem may be in the hardware:

• 🖥️ Old router — budget router processors (TP-Link TL-WR841N, D-Link DIR-300) cannot cope with modern loads.
• 📡 Weak Wi-Fi adapter — built-in laptop adapters are often worse than external USB adapters (ASUS USB-AC68).
• 🔌 Cables and connectors - a damaged Ethernet cable or oxidized contacts can add delay.

Minimum requirements for stable ping in 2026:

8. Additional methods: from mesh networks to alternative protocols

If standard methods don't help, try:

• 🔄 Mesh system - if the problem is in the weak signal (for example, TP-Link Deco or ASUS ZenWiFi).
• 🔌 Powerline adapters — for transmitting Internet via electrical wiring (suitable for thick walls).
• 📡 Bridge mode (WDS) - if you use the second router as a repeater.
• 🔗 IPv6 protocol - in some cases reduces latency (check with your provider).

For advanced users: on routers with firmware DD-WRT or OpenWRT can be configured manually Bufferbloat (using Cake or FQ_Codel), which significantly reduces latency under high load.
