Hello @Gingerbeardyman, sorry that your wifi appears to still be intermittent.
I've ran some checks and it appears that there seems to be some issues with the power levels on your Hub, potentially impacting your performance to date.
I'm going to pop you a quick PM to ask you to confirm some details, just so I can arrange a technician to come to you to get this fixed.
Please expect this PM to arrive within the next few minutes!
Many thanks
