How many Mbps (that Mega bits per second) do other devices (say, a friends laptop) with a gigabit Ethernet port, and a shorter cable of the same quality, do?
I assume that you turned off all other, possibly interfering, software like firewalls and antivirus programs.
- what's the speed if you boot into a Linux disc or stick (free to make). Try it on your PC and on your friends laptop.
- Connect two 300 Mbps devices and test both simultaneously. If the speed slows down to 150, the bottleneck is in or behind the router. If the speed stays 300 on both, the bottleneck is the end points.
Please let us know the results of all experiments and your conclusion.
I have gigabit internet service through spectrum. a Nighthawk AX8 Wifi 6 router. my nighthawk app on my phone shows that the router speed tests at around 900 MBPS. i have a custom PC with a Asus Z170 motherboard. the computer is hard connected with a cat7 ethernet cable that runs about 50 feet to the pc. no matter what i do i cant get my PC to speed test higher than 300MB what do i do?
