Can anyone explain this please: I have a new Virgin bb system. When I run the Virgin Broadband speed checker I usually get around 30-40 mbps download. If I run the same speed checker immediately again I get around 12 mbps. If I then run the 'Which' speed checker I get around 12 mbps. Which speed is right? I have done this repeatedly over a few days and I always get this higher speed on the first run and the lower speed on all subsequent runs, unless I leave it for an hour or so and then it follows the same pattern again.
I have a Virgin router attached to a tv by an ethernet cable and all my other equipment (desktop computer, iPad etc) attached with wifi.
speedtest.net is usually regarded as the most consistent site for speed checking (I only ever use this one). You should first check the speeds on a Cat5e/6A ethernet cable (attached directly to the Hub} on a gigabit enabled laptop/computer booted into "Safe mode" (if its windoze) also with the Hub in modem mode - this takes out any "throttling" due to software running on you computer/laptop and any other network traffic. That's your baseline connection speed - the one that you are paying for !. Then go back and check how wifi compares to that.
