Ethernet Settings Nforce 780i

Anyone know what I should set this stuff up as? I seem to be having latency issues and connection instability that my ISP swears is something on my end.

I'd appreciate any info on these settings, if you're wondering I'm advertised a 6meg download/ 384 upload and my speeds bounce around from 900kbps - 5.5 Meg, differing just about every time I speedtest it. My latency is ALWAYS horrible, no matter how fast the connection is running. I've been dealing with over 300 ping to Chicago, which is 3 1/2 hrs away.
