Thanks but ive disabled both auto channel and smart WiFi, but the problem is still there
There's a bit more to it than that.
Having disabled the auto channel selection and smart you need to check that your hub is set to use different channels to whatever your neighbours are using. You can check what channels they are using by using a Wi-Fi analyser app (free) other than the Virgin one. A shortcut is just to try changing the channel - preferably keeping to 1, 6 or 11 on 2.4 GHz - also checking 5GHz too.
Unfortunately WiFi is somewhat more complicated than Virgin and the other providers have tried to make it!
Ultimately you may be better off getting your own third party Wireless kit or router and using the Virgin Hub in modem mode no matter how much you feel you shouldn't have to do so. Higher end third party kit generally copes better than the 'down to a price' offerings from VM and other ISPs which might well work okay in many situations, but not yours.
