I've been using the machine all day with the bluetooth disables without a problem with the wireless.
I've wasted a week with trying to get this laptop to work properly so rather behind with what I should be doing work wise. I'll have to have a play with the antivirus and bluetooth some other time now.
For reference I'm using Microsoft Security essentials on all of my machines here and Windows Firewall so nothing out of the normal. This is the only machine I've ever had an issue with on my network (Apple / Linux / Windows / Android) and it hasn't worked properly (from new on either Win8 preinstalled or a fresh Win7 install) on any of my routers or access points.
