Welcome to the community!
Sorry to hear you're having WiFi issues at this time. I am not able to look at our systems to see if any issues are affecting you at this time due the the lack of information. Could you please provide some further information and checks so we can look into this further.
Firstly, please try a 60 second pin hole reset on the router. This will revert any customisations back to factory settings and full update the router with firmware/software updates. Please do not reboot the router whilst it is completing the pin hole request.
If you are still having issues after this please try setting up a Broadband Quality Monitor and post a link to your live graph.
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum
Once we have this extra information we will be able to offer you the further support you need!
If you could also post your Hub status and logs after you have rebooted and waiting a few hours for the data to collect. Here are steps on how to do this;
• Please go to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
• Don't log in, click on 'router status'
• Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. Please do not include your MAC address.
