The benchmark will always be a fairly new/decent laptop or desktop with a Gigabit NIC wired directly into the main router. If you do the same file and same site to reduce.variables to each device. You can download some large files here: Download Test Files | thinkbroadband Older devices are generally slower and wired and wireless network adapters generally get faster the newer they are. That is a tool we use a fair bit on customer sites to troubleshoot and proof speed between points. Only true way you can get an accurate speed test is to use something like iPerf between two points with least variables and known good high speed and device at other end. It has taken some hours so far and will take many more. I've been in the game over 25 years and just troubleshooting a wireless issue on one AP out of 4 in my place. There are so many variables often it is unreal and it is getting much harder to troubleshoot issues. A kin to a car on a rolling road with flywheel and wheel horse power I guess.

You will never ever get 100% as there is overhead and losses routing through devices. Wireless is often much slower than wired. As above check some different speed checkers.
