the only way you are going to get a new shub is by directly connection a pc (which means long patch cable from upstairs if you don't want to move your pc downstairs) because the only test VM will accept is from a single device directly connected to the shub so they can rule our wireless interference and any 3rd party hardware (e.g. if you was using your own router). Using a shub 2 will go a long way towards fixing your problems but I still think there are two of three contributing factors. The other two is wifi and electrical interference through the powerline adapters. All of that would be fixed by either getting a proper router with decent wifi or running patch cables straight to the router for a wired connection, all of which I said in my first post. Getting a new router wont fix the interference between your router and the powerline adapters. If you need want a perfect connection for gaming you need to fix all the problems and not just one.
