Hello, I have just bought a new Fujitsu laptop which I have connected to the same router as my wife's Samsung. We have both run download speed tests on speedtest.net one after the other and she is getting a constant average of 21mbps and I am getting a constant average of 3 mbps. we have no other downloads running and my laptop seems to be a higher spec than her's. I have tried turning off both the avast virus protection and windows firewall and re-running the test but get the same results. The laptop has only been turned on for the first time this evening so I would expect everything to be perfect. Please help.
