My Vista Home Premium laptop gives strange results when I check the download speed on any of the speed test sites. I have a 10Mbit cable connection, but www.speedtest.net
(for example), shows a speed of up to 150Mbit... It starts off very slowly, around 1 Mbit, then bursts up to some crazy speed towards the end of the download. The upload speeds are always pretty accurate (about 1 Mbit). Download speeds for large files (rather than just tests) are generally much less than they should be (as low as 10-20%).
When I boot into safe mode, the speedtest.net results are as expected (around 10 Mbit). Same when I check the speed using an XP machine.
Device Manager shows the network card to be a Realtek RTL8168C(P) Family PCI-E Gigabit Ethernet NIC. I've tried several different drivers, and uninstalled and reinstalled drivers in safe mode, but nothing has made any difference.
Can anyone help me please?
