I just setup a Ubiquiti UniFi Cloud Gateway Ultra (UCG-Ultra) to replace a Ubiquiti EdgeRouter 4. There were no problems with the EdgeRouter, but I wanted some of the additional network management functions found in a UniFi gateway.
I have the 1 Gig plan with Google Fiber. Doing a speed test using Ookla's Speedtest app in my Mac was yielding around 700 Mbps download whereas I was getting about 930 Mbps using the EdgeRouter. I was able to fix the problem by changing the WAN port 1 Gbps FDX. By default it was set to auto-negotiate and appeared to be negotiating at 2.5 Gbps to the Fiber Jack (ONT). The mismatch between the service speed and the ethernet speed must have caused the slowdown since I'm now seeing my expected speeds.
