As the title says, I've got an ethernet card but not enough specs information.

I have tried looking in Device Manager -> Properties but no dice. Google searches haven't revealed much.

The card is an

Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller(NDIS6.20)

...and I'm specifically looking for maximum data transfer rate of the card.

Any links or ideas?

It's a Gigabit ethernet card, so 1000Mb/s but it'd be nice to have a neat way to prove it!

+1 for the info - yes, it would be nice. How'd you know that it's a Gigabit? – Ben Mar 25 '11 at 5:06
I googled the first bit of that line, I googled Atheros AR8121/AR8113/AR8114 . The first link says "Atheros Communications Inc. (R) AR8121/AR8113/AR8114 Gigabit/Fast Ethernet Driver " – barlop Mar 25 '11 at 5:58
Finding the datasheet for free isn't that likely..… "Bad news for you Cedric. Atheros, like Broadcom, Marvel and others.....pretty much won't talk to you unless your building 250K+ EAU. Atheros has authorized design houses, with contact information on the website. If you want to engage with them, its $10,000 to do so, and that gives you access to datasheets and not much else. How do I know? Well...we went down this path about a month or so back, and decided that it wasn't worth doing. " – barlop Mar 25 '11 at 7:54
but a google of atheros data sheet 8121 comes up with but I can't see if they've got it there and if they do it looks like they charge. – barlop Mar 25 '11 at 7:56
@barlop - Cheers mate, helpful anyway, thanks. – Ben Mar 25 '11 at 23:38

According to this page, it's 10/100mbps card.

It is definitely NOT ALWAYS a gigabit interface...!

I own an Asus Eee-PC 901 with UMTS module which has this ethernet interface. A long time I thought to have a gigabit ethernet in it - but yesterday I found out it is not (against a Pogoplug E02, which allows a gigabit connection with same cable and another PC with same OS), my AR81xx has a maximum link speed of 100 MBit/s.
