Hey Trix100, thank you for reaching out and I am sorry to hear you are having some CCTV issues.
Can you try and put the cameras on the 5GHz?
If you haven't done this already - try it first - it helps sort some Hub3/4/5 wifi issues for some devices.
Go into the Hub’s settings. Type in http://192.168.0.1 into your web browser’s url box and login with settings password on the Hub's base sticker (or your own if you changed it). Then in Advanced>wireless signal >smart wifi - tick the disable “channel optimisation” box or the“Smart Wifi” box and save settings. May be different pathways and wording on the 3 Hub types This (message 2) is for a Hub3… https://community.virginmedia.com/t5/Networking-and-WiFi/Hub-3-Wi-Fi-constantly-dropping/td-p/5391375
Then, go to advanced>wireless signal>security, rename the 2.4 & 5 GHz network ssid's. Just type over to change 'em to whatever you like and something that will differentiate them (e.g - TP4_2 & TP4_5) Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices. Use the same password for simplicity, Then, apply settings and restart the Hub. Your 2 wifi networks will now be clearly separated - and you can then select the network you want each device to connect to… individually from the "available networks" list on each of your devices. Cheers
