This solution didn't work at first for me, but it worked second time with delayed_ack=1. Thanks a lot man. You are the KING!

Hello Lnx2Mac
can you please help me with mine
GA-Z68MX-UD2H-B3
LAN problems?
I'm Using the
the Realtek Gigabit Ethernet 2.0.6 from latest multibeast
the Card is recognized, I got an Ip with DHCP
but the LAN is Unusable SLOOOWW like 1Kb/s
tried changing the DELAY HACK with Terminal but no luck!
any hints please?
thank you very much!

1Kb/s is just to say that it sucks!
Anyway I've done a speedtest and I can't browse internet because every website takes minutes to load, and sometimes stop loading

First of all, check http://bit.ly/DeadNIC it might help...
Then, don't use speedtest... start by testing on LAN...
Also, if using a different OS on this machine, does the network work better ?

Sadly trying also on Linux seems that my LAN is ****ed!
somwtimes i got the IP but speeds are always impossiible
damn the Mobo Is New!!
maybe is better that i Stuck with the little usb wifi adapter
because If i should RMA or change the mobo I think it will be a looong story
what do you suggest?

Specially, check your cables, connectors, verify there's no lint in the port.

Thanks for responding in my other thread lnx2Mac!
My server is Windows 2000 AS, so I had to google a netserver that will run on it.
Run netperf on the Mac .
Is this the real-world limit? The Max output I can get is 645 Mbit/s
using online conversion of 645 Mbps -->
= 80.63 MB/s
= 645.00 Mbps
= 76.89 MiB/s
= 290.25 GB/h
= 4.84 GB/min
Thanks to Belmore, this time I used the "time cp" command and copied the Mac 10.6.7 OSXCombo update to my Windows file server.
net.inet.tcp.delayed_ack=2
time = 22.009 seconds to copy the 1.06GB OSX combo file
But doing simple math, that equates to only 48 MB/s. ... instead of the 80MB/s number I got above. Where did the rest go? Overhead? or slow hard disk speed (RAID 1).
I did try other ack values.... but my average output stayed roughly the same.
