@Ripcord

Unfortunately for you the Hub two does not have any QoS settings.

Which product do you have, hopefully you are testing using a wired connection?

Where are you see this latency?

The Hub two is not the best for bufferbloat, do you have any applications that is using the uplink like cloud saves that could be active. This will use up some of the bandwidth. A wired connection would be best as wifi can add to the bufferbloat.

Check if Full Fibre is available to you here:- https://www.broadbandchecker.btwholesale.com/#/ADSL/AddressHome

This site https://www.openreach.com/ will hopefully indicate if/when Full Fibre will be available to you.

A third party router supporting QoS might improve the situation.

So a diagnostic tool suggests you might have a problem … but what real world issue are you actually experiencing?

If you want lightening performance you’ll need to buy your own high performance router … but will it make any meaningful difference to your use of the internet?

Be careful that the “diagnostic” is not nothing more than a “vector” to part you from your dosh to buy something you do not really need. The “diagnostic” very much looks like “here is a problem you might not know about and here is a solution you do not really need - but we will earn commission if you buy”.

I don't particularly trust the program - my laptop never moves, is permanently on 5Ghz, but can give buffer-bloat results of B to E
