Ever since I got my new Virgin SuperHub, I've found Safari can be really frustratingly slow. Often, but not always, the progress bar will move an inch and just sit there stubbornly. Usually if I click reload, it will whoosh along and load the page. Similarly, I'm regularly getting Mail telling me there's a connection problem: turning WIFI off and on again seems to deal with that. Yet whenever I do a speed test on my WIFI from my Mac I get great results. I just ran one now: Ping 16ms, Download 73.35Mbps, Upload 5.07Mbps. All this happens even if I'm sitting within 6ft of the router. Any ideas or suggestions?
