Atheros NIC not coming up at capacity

**t-readyroc** · April 20th, 2010

Just rebuilt my file/print server using an ECS 945GCD-M Atom motherboard. Running it under 9.10 (2.6.31-20) using the same cable and port on my Netgear switch that my old server connected to at 1GB/s without issue (old server's NIC was Intel-based).

Did some forum searching. Found the driver is an AR813x, & downloaded & installed the latest driver from here (1.0.1.9). sudo lshw -C network now shows that it's using the new driver, but still sitting at 100MB/s:

Code:

/etc/init.d/networking restart does the following:

Code:

   ...done.

ifconfig output:

I can't seem to get it to come up at the full 1GB/s. I also tried ethtool -s eth0 speed 1000 without success. Also, any idea why networking restart ignores eth0? Any help would be appreciated.
