Hi everyone.

I own a computer with an Asus M4A78LT-M LE motherboard, that comes with a Qualcomm Atheros AR8131 PCI-E Gigabit Ethernet card.

Today I changed my 100mb fiber connection for a FFTH 200mb simmetric connection.

The thing is that while I'm getting 200mb download on Ubuntu, it won't go faster than 100mb on Windows 8.1 ... the test websites I've tried seem to freeze when downloading and don't got further that 100mb ...

Anyone can give me a hint on what can be failing? I've downloaded the latest drivers and that didn't fix it...

Here is the info I get from my network card on windows:

possibly the websites you are testing with are limiting bandwidth. Are you getting greater than 100mb from any website when using windows?

I've been doing some more tests and I've found that it has to do with flash websites... as mainly all the speed test sites are flash made, it seems my old dual core is choking with flash... strange because this doesn't happen on Ubuntu.

When I download a file from MEGA, for example it rockets to 19MB/s (that's near the 200mb/s) and using JDownloader with paid account, I got 23MB/s from Alldebrid > Uploaded ... so it seems to be working...
