Features We Don’t Like

Lack of Multi-Gigabit Ports

The MSI RadiX AXE6600 only has a singular multi-gigabit port, the red WAN/LAN port. It’s a shame that there aren’t additional high-speed ports on this router, as this limits speeds through a wired connection, which many gamers prefer due to stability. If you’re the kind of gamer who needs multiple high-speed wired internet connections, it may be worth looking at alternative routers.

MSI AXE5400 Bandwidth Capabilities

We’ve tested the bandwidth capability of the MSI AXE5400 WiFi USB adapter to see how it performs at different ranges. This shows us how the AXE5400 will hold up in a real-life context where the router might not be nearby. To test this, we ran the ‘Internet speed test’ through Google Chrome, which evaluates a given network’s download, upload, and ping speeds.

Close-Range Bandwidth Test

In the close-range test (around 3ft from our router), WiFi speeds were as expected across the 2.4GHz and 5GHz bands. 2.4GHz is a much more congested and narrow band, so the 62.1Mbps and 67.2Mbps across download and upload speeds are the best we will get. However, it is worth noting that our ping was much more stable here, with a 5ms response time.

On the 5GHz band, our download and upload speeds surged to 306.1Mbps and 284.3Mbps, respectively. This demonstrates the stark difference between the 2.4GHz and 5GHz bands and the importance of using 5GHz or higher when available. Ping remained at 5ms within this benchmark.

30ft Range Bandwidth Test

During this testing run, we moved 30 ft away from our router and reran the same test across both available networking bands. The 2.4GHz test showed relatively poor results, with the AXE5400 barely offering a single megabit on the download speeds. Our upload speeds were more substantial at 8.6Mbps, and the ping sat around 7ms.

The likely explanation for this is interference. Moving further away from the router results in us crossing streams with other overlapping wireless networks, which can result in slower speeds. Physical obstructions such as walls, metal, and even furniture can significantly dampen the strength of WiFi connectivity.

The 5GHz performance is slightly diminished here compared to the close-range test, with our download speed at 152.2Mbps and our upload speed at 256.3Mbps. Admittedly, the ping didn’t change much, with only a slight increase to 6ms instead of 5ms. It’s excellent that performance hasn’t dropped off significantly here using the 5GHz band. These speeds would be ample for general day-to-day workloads or light gaming.

50ft Range Bandwidth Test

Our final bandwidth test was run 50 ft from the router to see if the connection would drop. Fortunately, the MSI AXE5400 held up pretty well, and we didn’t see any connection loss during the benchmark. However, we started to experience signal instability, which resulted in some odd numbers.

The 2.4GHz benchmark saw improved speeds over the 30ft bandwidth test, with a slight increase in upload speeds up to 11.6Mbps versus 8.6Mbps. Ping also increased from 7ms to 8ms. Admittedly, the numbers aren’t much different from the 30 ft range test, but our results were relatively volatile during the benchmark. This demonstrates that the further away we get, the more instability we’ll likely see over WiFi.

The 5GHz test saw a slight improvement in bandwidth, with the MSI AXE5400 offering 192.9Mbps for download speeds and 283.9Mbps for upload speeds, while our ping dropped to 5ms. The results are better here versus the 30-foot test, but due to the unstable nature of the signal, the speeds will continue to worsen and become less stable as the distance from the router increases.
