Here are some rough throughput benchmarks I did to find the approximate maximum bandwidth a router can handle. Tested with iperf3. I’m a noob at this so I don’t know if I benched properly, take these test results with a grain of salt. I’m also open to suggestions. You can email me at email@example.com for that.
The pings shown in these videos are pings to my Surface Pro 4 from my Desktop.

As of 10/11/2018, I only have test results for the TM-AC1900.
