Recently upgraded to 500MBps, slower than anticipated speeds

Hi folks,

We've recently upgraded from 100Mb/s to 500Mb with the extra time spent working and streaming from home. While we've seen speed increases across all devices, they're quite shy of the 500Mb promised.

At the moment we've got our HUb 3 set up in modem mode connected via an Asus RT-AX86U router and on the one machine that's hardwired with Cat-7 cables to and from the roouter (overkill I know), we're only getting around 240Mb. This has been duplicated when I pllug the same cable into a laptop.

There now follows a ton of numbers I don't really understand at all. In browsing for possible solutions I've gathered that something is wonky with channels 23 & 24, and possibly 1?

Any help much appreciated!

-Mark

Re: Recently upgraded to 500MBps, slower than anticipated speeds

Your downstream power levels are too low (In spec is -6 to +10).

Upstream power levels are quite high, but in spec.

Do you have one of these fitted?

Thanks for the quick reply Carl. No, nothing like that going into the Hub.

You'll need an engineer visit to correct the levels.
