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? –  Steve 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.. old.nabble.com/… "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 datasheetarchive.com/Atheros%20AR8121-datasheet.html 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. –  Steve Mar 25 '11 at 23:38

also try this Click the Start Button and then click the "Programs" folder. Next, click the "Accessories" and then the "System Information" folder. ..or something like that, depending on your operating system this route may vary in name etc. Within the System Information window, click the + symbol next to Components. Click the "+" next to "Network" and highlight "Adapter", in the right side of the window you should be able to locate complete information about the network card...or at least alot of info from this area.

According to this page, it's 10/100mbps card. http://www.atheros.cz/atheros-network-drivers.php

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.
