6 GHz Wi-Fi Tested: The Clear Winner

Shenzhen China — Do you game on LAN or Wi-Fi? Does the network lag ever pull your gaming performance? Cudy testing team have some raw testing figure that shows how good 6 GHz Wi-Fi for wireless online gamers, especially in stabilizing the latency.  

"6 GHz Wi-Fi has been here for a while, but not a major vendor has officially showing its testing data" said Levi Li, the Testing Engineer at Cudy "we want more people to know how perfect the 6 GHz is for gaming, so we bring these test data to you."

This article will introduce what 6 GHz Wi-Fi is, how 6 GHz benefits gaming experience, and the test data of speed and latency in comparison with 5 Ghz Wi-Fi. Welcome to the 6 GHz gaming.

TL;DR

The 6 GHz Wi-Fi band is a "clean slate" band with minimum interference brought by Wi-Fi 6E and Wi-Fi 7. "Almost no interference" is its strongest advantages over another two Wi-Fi band.

In our tests, compared with 5 GHz Wi-Fi, Cudy 6 GHz Wi-Fi adapters reduced latency by ~40% (based on 300+ records) and jitter by ~80%, delivering a smoother online gaming experience in a noisy Wi-Fi environment—even with a wall as a physical barrier.

Straight to the data >

Cudy tri-band Wi-Fi 7 routers M21000, WR11000, and M11000 enable gamers to deploy seamelss 6 GHz Wi-Fi throughout their homes. If they don't have 6 GHz adpater on their PC, Cudy provides plug-and-play tri-band USB Wi-Fi adapters WU6500, WU5400, and tri-band PCI-E Wi-Fi adapter WE9300S, WE9300, and WE3000S for PC gamers to upgrade their PC and enjoy the best of 6 GHz Wi-Fi. 

6 GHz Wi-Fi — The "Clean Slate" Band

Wi-Fi has been using two wireless bands to transmit data — 2.4 GHz and 5 GHz — for a long time. 2.4 GHz is a crowded band which has been used by microwaves, cordless phones, and even garage door openers. As we demanded more bandwidth and fewer interruption cutting our Zoom calls and gaming lags, Wi-Fi introduced the 5 GHz band, which offered faster speeds, more channels, and less interference — at least for a while.

In a wired setup, Ethernet cables give each device a direct, interference-free connection to the router or switch, so data travels fast with almost no loss. But running cables to multiple rooms or devices can get expensive, and if there’s no port nearby your computer, you end up with messy, visible wires that don’t look great in your space.

As everything goes wireless and our homes filled up with smart TVs, gaming rigs, and streaming apps, Wi-Fi needed more room to breathe.

Now we’re stepping into the 6 GHz era, enabled by tri-band Wi-Fi 6E and Wi-Fi 7 routers and adapters. Unlike 2.4 GHz and 5 GHz, this spectrum has never been polluted by legacy technologies — a true ‘clean slate’ band.

This "Clean Slate" means:

• Less legacy clutter: No interference from older 2.4 GHz or 5 GHz devices, nor from any other home appliances.
• Wider lanes: More wider 160 MHz / 320 MHz channels, make it easier to establish and maintain faster connections. 
• Lower latency and higher speed, in busy homes or offices, perfect for high-speed, low-latency applications like gaming, VR, or 4K streaming.

WR11000: Tri-Band Devices Access The 6 GHz Band with Minimum Latency

There’s a common belief that Wi-Fi on higher frequencies doesn’t travel as far, but our tests show it’s not an issue at all. In busy apartments or cities, even through walls, the lower noise and ability to maintain higher data rates still give you a cleaner connection and more stable latency.

Latency is the Key to Online Gaming

Online gamers are familiar with PING, which represents the time it takes for a data packets to travel from your computer to the game server and back — the latency. While Wi-Fi speed matters for downloading updates or streaming, it’s latency that determines whether your character moves the instant you press a key or ends up reacting a fraction of a second too late.

In competitive gaming, even a 20–30 ms difference can mean losing a duel or missing a critical shot. High latency leads to lag, rubber-banding, or delayed actions — all of which are game-killers.

Another key factor is jitter, the variation in latency over time. You might have a low average ping, but if your connection spikes unpredictably, the gameplay still feels choppy.

6 GHz is wider, cleaner, and suitable for higher-speed, latency-sensitive tasks

The 6 GHz band helps here by reducing interference and congestion, which are major causes of latency and jitter in 2.4 GHz and 5 GHz networks. With cleaner airwaves, data packets travel more directly and consistently, resulting in smoother, more responsive gameplay.

In short: for gaming, latency stability > raw speed — and 6 GHz delivers both.

The 6 GHz Test

How We Did the Test

We picked Cudy WU6500/WU5400/WE9300 and four more 4-stream dual-band adapters to get their latency and speed performance in three different environments to measure how good the 6 GHz Wi-Fi can be.

• PC
  • OS: Windows 11 24H2
  • CPU: Intel 
  • Memory: 16 GB
• Main Router
  • Cudy BE11000 Wi-Fi 7 Router — WR11000
  • Another BE11000 Wi-Fi 7 Router
  • Both routers are connected to a 2.5 Gbps broadband service
• Environments
  • Cudy Office: 50+ surrounding Wi-Fi.   
  • Cudy Snacks Room: 50+ surrounding Wi-Fi. 
  • Cudy OTA Chamber: almost 0 interference environments. 
• Testing Methods
  • Latency: We connected the PC via the 6 GHz or 5 GHz network to the Internet, and then connected to testing services of online games by top game vendors, and record 300+ continuous latency values. We repeated the testing process in three environments. We also connected via Ethernet to get data for reference.
  • Speed: We connected the PC via the 6 GHz or 5 GHz network to the Internet. We used Cudy speed testing applications to get the TCP throughput data to and from a self-built server via the router. We repeated multiple times and record the max throughput number.
• How We Processed the Number
  • Latency: we recorded the maximum and mininum latency, and we used standard deviation of all latency values in the group to represent its stability level (Jitter).
  • Speed: we recorded the maximum throughput number to represent speed performance.

The Result — Latency

Scene 1 Cudy Office (50+ Neighboring Wi-Fi)

Cudy office, where we have more than 50 Wi-Fi points, poses an intense challenge to wireless gaming. The test result shows a 5 GHz band can hardly provide consistent low-latency in such an environment, with sudden "lag spikes" happening frequently, disrupting the gaming experience. In contrast, 6 GHz adapters draw smooth and almost-flat lines, providing a consistent low-latency network, obviously because there are few 6 GHz band interference, allowing the game frames to respond instantaneously.

Cudy testing engineers then moved the PC client into the Cudy Snacks Room, where the transmission path had to pass through a wall. This scenario better reflects real-life conditions in large houses, where an immovable blockage stands between your PC and the router. In this environment, latency fluctuated more sharply on 5 GHz devices. On the 6 GHz side, two Wi-Fi 7 adapters (WU6500 and WE9300) maintained impressively stable connections, while the Wi-Fi 6E WU5400 experienced minor turbulence but still kept latency below 30 ms.

To confirm that interference was the real cause of the difference, Cudy’s testing engineers also ran the device in an OTA chamber as control group, where all possible interference is absorbed. In this optimal setting, both 6 GHz and 5 GHz performed similarly well, with quality comparable to an Ethernet connection.  

The Result — Speed

Scene 1 Cudy Office (50+ Neighboring Wi-Fi)

In Cudy’s office environment, which is crowded with neighboring Wi-Fi interference, three PCs equipped with 6 GHz Wi-Fi topped the benchmarks in both RX and TX throughput, outperforming all non-6 GHz adapters. Thanks to its external antennas and heatsink for dissipation, the WE9300 claimed first place, fully utilizing the bandwidth originated from the WR11000’s 2.5 Gbps ports.

When wall blockage combines with an interference-heavy environment, the advantages of 6 GHz become even more significant—delivering more than 3x the RX throughput of 5 GHz, whether using a PCIe adapter with high-gain external antennas or a tri-band USB adapter.

Still, our engineers did testing in the Cudy OTA chamber to confirm these devices can all realize their full speed in a no-interference environment.
