Hello Goodnight. I recently upgraded from 100mbps to 900mbps. I'm doing the speed test and the Google Mesh Wifi routers on all devices (pc, iphone, android, tablets...) show me a speed of less than 300mbps. Does someone know how to solve this problem? The maximum speed for these mesh wifi is supposed to be more than 1gb. Cheers!!
Wi-Fi speeds are theoretical, hypothetical.
To get faster than 3-400mbps Wi-Fi speeds, you should look into equipment that supports the newer standards, Wi-Fi 6 or even 6E. And clients (PC, phone etc.) that can take advantage of it, which isn't a given.
If you can hardwire devices, you'll be able to get gigabit speeds. You can add more LAN ports by adding an unmanaged switch to the mix.
