Linksys Velop - slow Wi-Fi when broadband speed increased

So I have a two node mesh system.

Upgraded my home broadband from 70mbps to 150mbps but my Wi-Fi speed was stuck at 68mbps.

Spend a few days trying to debug. New cables. Multiple restarts etc.

Turns out you should disable and reenable device prioritisation in the Linksys app if you increase your Broadband speed. This will recalculate the limits based on the new speed.
