You've posted saying your WiFi is dropping, are you seeing the same issues on wired connections. Virgin supply you with a broadband connection which your router converts into wired & wireless connections. WiFi dropping is a router issue, broadband dropping could be a VM issue - it's important to differentiate.
Do you have a BQM running? Free, takes all of 10 minutes to setup and monitors your connection 24/7 providing excellent diagnosis & evidence of network issues. If you don't have one, please set one up and give it a little while to start generating useful data - then post a link to your live graph.
