10 Gbit/s Speed: UXG-Pro with Fiber7-X

Upgrade to a lightning-fast 10 Gbit/s connection with Fiber7 from Init7 and the UniFi Gateway Pro (UXG-Pro). This setup ensures faster downloads, advanced security, and improved performance. Discover how to achieve high-speed connectivity affordably and optimize your network for the future.

10 Gbit/s Speed: UXG-Pro with Fiber7-X

Introduction & Main Upgrade Goal

Upgrade your internet speed affordably by switching to a lightning-fast 10 Gbit/s connection with Fiber7 from Init7. The main goal was to bid farewell to the aging UniFi Security Gateway (USG) and embrace the superior performance and advanced security features of the UniFi Gateway Pro (UXG-Pro). This upgrade ensures not just faster downloads but also a smarter, safer internet experience, aligning with evolving security needs. Thanks to Fiber7, achieving high-speed connectivity with our Ubiquiti UniFi gear is now cost-effective. It's like upgrading to the fastest internet without burning a big hole in our pockets! πŸš€πŸ’»

Speed Tests and Results

The built-in Speedtest feature in UXG-Pro lacks the ability to change the speed test server, unlike some users with UDM Pros who claim success using the Wifiman app to switch servers. However, the UXG-Pro, with its current version "3.2.17", does not exhibit this functionality. Additionally, there are indications of CPU reaching maximum utilization during download tests.

Numerous posts about UXG-Pro highlight concerns that the Speedtest results may significantly deviate from the accurate ISP speed, a discrepancy believed to be influenced by the location of the Speedtest servers.

UXG-Pro articles about built-in speedtest issues:

Update from Init7

Init7 has announced the setup of their own speed test server for Ubiquiti UniFi devices. According to this tweet on X.com, Init7 now offers a dedicated speed test server for UniFi users πŸ‘.

My speed test results have slightly improved with the new Init7 UniFi speed test server. However, the CPU on my UXG-Pro still reaches 100% during download tests.

Iperf3

When directly employing iperf3 in the UXG-Pro console (via ssh), impressive speeds approaching 9.2 Gbps are achieved, aligning closely with the real-world maximum of approximately 9.4 Gbps. It's essential to emphasize that the iperf3 server you connect to must support a minimum of 10 Gbps and be in close proximity to accurately reflect the true speed offered by your ISP.

iperf3 commands for speedtests using the Init7 iperf3 server:

iperf3 -c speedtest.init7.net

# -R => run in reverse mode (server sends, client receives)
iperf3 -R -c speedtest.init7.net

# Three speedtests in a loop with random sleep between 10-40 seconds:
for i in {0..2}; do echo "> $i"; iperf3 -c speedtest.init7.net; sleep $((RANDOM % 41 + 10)); done

Real-world Performance

Example results with iperf3 using my ISP (Init7) iperf3 server which should support 20Gbps:

for i in {0..2}; do echo "> $i"; iperf3 -c speedtest.init7.net; sleep $((RANDOM % 41 + 10)); done
