While Wi-Fi 7 is right around the corner, many are still getting acclimated to Wi-Fi 6E. We’ve already tested several Wi-Fi 6E routers, with the latest coming courtesy of MSI.
MSI’s RadiX AXE6600 is a compelling entry into the wireless gaming router field with its array of six antennas and heavy use of MSI’s Mystic Light to liven things up stylistically. MSI also enhances the RadiX AXE6600 with a 2.5Gbps WAN/LAN port (one of the four remaining 1 Gbps ports can also be used for WAN if you desire).
Available for a reasonable $256, RadiX AXE6600 delivers good looks, a comprehensive web GUI and performed well in our benchmarking suite. That makes it one of the best gaming routers available and also one of the best routers overall.
Looking at the router, the feature that stands out most is the antenna array, with six poseable elements along its sides and back panel. Each antenna features an LED for syncing with MSI’s Mystic Light. There’s one additional LED located in the MSI logo on top of the router.
Interestingly, while you can enable Mystic Light from the web interface (or using the smartphone app), you cannot adjust the colors using these methods. Instead, you must install the MSI Center app on a Windows PC to change the RGB settings.
A status panel near the top rear of the router also highlights internet connectivity, power status, and activity from the four gigabit ethernet ports. There are also buttons for Wi-Fi and WPS, along with an “LED Off” button which, understandably, turns off the LEDs on the status panel.
Moving around to the rear of the router, you’ll find a 2.5 GbE WAN port, four GbE LAN ports, a USB 3.0 port, and a power button. There’s also a plethora of vents along the front, sides, and bottom of the RadiX AXE6600 to keep the router cool.

MSI RadiX AXE6600 Setup
Although you can set up the RadiX AXE6600 using a smartphone, I used the tried-and-true web browser method. After navigating to the http://msirouter.login address, I could log in using the credentials printed on the bottom of the router. Then, I was greeted with a vibrant, easy-to-navigate user interface with large buttons and clear graphics.
Thankfully, the router already had the latest firmware installed. However, updating the firmware is a simple affair. You just must navigate to Advanced → Administration → Firmware Upgrade. You can manually upgrade using a firmware package downloaded directly from MSI or an online tool that automatically checks for new updates and installs the firmware.
When you first login to the router, you’re greeted with the Dashboard, which presents information on hardware resources consumed and currently-connected devices. You’ll also find presets to change the router’s QoS (Quality of Service) settings. The four that most users will likely enable at some point include AI Auto, Gaming, Streaming, and WFH.
There’s also a dedicated Game Center subsection where you can enable Game Boost mode. If you select the Traditional QoS mode, you’re also given the option to prioritize MSI devices. Game Center is also where you’ll find controls to enable the Mystic Light function.
Like most Wi-Fi 6E routers, the RadiX AXE6600 ships with three wireless bands enabled (2.4GHz, 5GHz, 6GHz), each with its own SSID. In this case, the router defaulted to MSI_2G_FE, MSI_5G_FE, and MSI_6G_FE as the SSIDs, but you will want to set your own.
However, the RadiX AXE6600 can also use Smart Connect, which sets a single SSID for the router. Whether your device maxes out at Wi-Fi 5, Wi-Fi 6 or Wi-Fi 6E, it will connect to the router using the same SSID, with the client choosing the appropriate band automatically. However, keep in mind that Smart Connect can often diminish network performance.
The Radix AXE6600 offers basic parental controls, including the ability to filter for Adult content, gambling, violence, drugs/firearms, malicious content and games. Each is individually selectable, and you can specify the MAC address to which the settings apply.
MSI RadiX AXE6600 Performance
We conducted multiple tests in a single-family, two-story home with a 500 Mbps connection, using a laptop with an AMD RZ616 160 MHz network adapter as the client. Another PC, attached via Ethernet, functioned as the server to receive traffic. We used iPerf to test throughput and ping to test latency. Four sets of tests were conducted on the 2.4-GHz, 5-GHz and 6-GHz bands:
Near uncongested: Testing laptop approximately 6 feet away from the router, no substantial traffic being carried across other devices
Far uncongested: Testing laptop approximately 25 feet away from the router, no substantial traffic being carried across other devices
Near congested: Testing laptop approximately 6 feet away from the router with videos streaming on four devices throughout the house
Far congested: Testing laptop approximately 25 feet away from the router with videos streaming on four devices throughout the house

The RadiX AXE6600 put up solid numbers on the 6-GHz band, as witnessed by our iPerf test scores. The RadiX AXE6600 can hit a theoretical 4,804 Mbps on the 6-GHz channel, but real-world iPerf numbers for every router we’ve tested are in the 150 to 550 Mbps range.
The RadiX AXE6600 managed 532 Mbps in the 6-foot iPerf test, which still far surpassed that of the next-closest competitor, the Netgear Nighthawk RAXE300. The results weren’t nearly as impressive 25 feet away, where the RadiX AXE6600 managed just 283 Mbps. Congested performance at 6-GHz was also strong, reaching 500 Mbps at 6 feet. However, that performance dropped at 25 feet, dropping to just under 200 Mbps, putting it well behind the other Wi-Fi 6E competition.
We witnessed a similar Dr. Jekel and Mr. Hyde performance at 5-GHz, with the 6-foot numbers coming in at a healthy 486 Mbps, well over 100 Mbps faster than the next-closest competitor. The tables turned at 25 feet, with the RadiX AXE6600 coming in at just 149 Mbps, below the average performance of the other assembled routers. With congested traffic, the RadiX AXE6600 pulled up last place at 6 feet and 25 feet.
At 2.4-GHz, the RadiX AXE6600 had some of the weakest throughput numbers of any router we tested. However, it still had very low latency and its speeds were more than good enough for the kinds of devices most people would have on a 2.4-GHz band (smart home devices, old tablets, etc).
The 2.4-GHz uncongested iPerf numbers reached 128 Mbps at 6 feet and 44.5 Mbps at 25 feet, both of which are quite low. The router slipped into last place among its competitors on the 2.4-GHz band when the network was congested, managing just 73.6 Mbps at 6 feet compared to 101.2 Mbps for the nearest competitor and 151.4 Mbps for the first-place Asus RT-AXE7800.
One thing that was consistent through all the tests, however, was the ping. Across 6-GHz, 5-GHz and 2.4-GHz channels with congested or uncongested traffic, the RadiX AXE6600 maintained speedy pings of 1 to 4 ms. Latency matters more than throughput when you’re playing games because most of the game data is actually on your PC, but your movements and commands need to reach the server quickly.
Bottom Line
The MSI RadiX AXE6600 offers strong performance on the 6-GHz band, a wealth of features, and striking looks at an attractive price point. On the other hand, 5-GHz performance was inconsistent, and 2.4-GHz performance put it at the back of the pack compared to other assembled Wi-Fi 6E routers. The RadiX AXE6600 has an MSRP of $349.99; however, retailers like Amazon offer the RadiX AXE6600 with a $90 discount, taking it to just $256 shipped.
If you have Wi-Fi 6E devices on your network, the RadiX AXE6600 is by far the best-performing router that we’ve tested. The numbers that the router was able to consistently deliver on the 6-GHz band far outpaced the competition at 6 feet and were in the same ballpark at 25 feet. 5-GHz performance was a bit more sporadic (although it took a considerable lead in the 6-foot iPerf test). 2.4-GHz performance, while on the lower side, is more than adequate for the older, slower devices that typically use that band.
We also can’t ignore that MSI has crafted an easy-to-use UI for configuration changes. There are plenty of presets for those that want AI to take over for QoS, or you can get down in the weeds and make granular adjustments on your own. And for those that aren’t enamored with the flashiness of the Mystic Light, it can be turned off.
If you don’t have any Wi-Fi 6E devices on your network or don’t plan on enlisting any soon, there are plenty of cheaper Wi-Fi 6 routers out there to consider, including the budget-minded Asus RT-AX1800S. But if you want blazing-fast Wi-Fi 6E performance, the RadiX AXE6600 is tough to beat.
