I recently retested the Ubiquiti U7 Pro Max and was initially disappointed by the slow progress on Multi-Link Operation (MLO) support. However, Ubiquiti finally released a beta firmware enabling MLO, and after some effort, I got it working on the client side. I used a Qualcomm FastConnect 7800 adapter with an unofficial driver update (which MSI later made official) and ran tests on Windows 11 with the experimental 24H2 update. Linux v6.11 now also fully supports MLO.
The U7 Pro has a 2.5GbE port, but I connected it to a 10GbE server to avoid bottlenecks, powered by the Zyxel XS1930 switch. Setting up MLO was straightforward with the latest beta firmware (v7.1.24). I aggregated the 5GHz (160MHz) and 6GHz (320MHz) bands, and Windows 11 confirmed the connection. The results were impressive: near-max throughput at 5 feet and improved performance at 70 feet.
Compared to the Zyxel NWA130BE, the U7 Pro performed better under high signal attenuation but lagged slightly at 30 feet. Aggregating all three bands (6GHz at 320MHz, 5GHz at 160MHz, and 2.4GHz at 40MHz) delivered nearly 200Mbps upstream at 70 feet, with strong downstream results. However, aggregating just the 2.4GHz and 5GHz bands showed weaker nearby throughput.
I also tested latency using Flent. The 6GHz band at 160MHz averaged 50ms latency, while 320MHz kept it below 50ms. Aggregating the 5GHz and 6GHz bands improved latency to around 30ms initially, rising to 40ms later. Using all three bands, the 320MHz width maintained consistent latency at 40-45ms, while 160MHz saw spikes to 75ms.
Overall, Ubiquiti has made significant improvements to the U7 Pro. I encountered no bugs or crashes during testing, though the WiFi 7 adapter occasionally struggled with the 6GHz band. If you have compatible hardware, the U7 Pro is now a much stronger option than before.

That’s a helpful review, @Mark B. I agree, the U7 Pro has noticeably improved, especially with the Multi-Link Operation. The speed and performance are worth mentioning. However, the 6GHz band seems to have intermittent issues, so users need to keep that in mind. For those who have the compatible hardware setup, the U7 Pro does indeed come across as a solid option now. The latency results sound pretty decent too. Would be interesting to see how it performs in heavy-traffic scenarios. Thanks for sharing your experience.
