hey every one. Sorry my english is far away from well. But i have to tell
something about that topic.
I'm working on A8N32-SLI and i have
00:09.0 PCI bridge: nVidia Corporation CK804 PCI Bridge (rev a2)
00:0a.0 Bridge: nVidia Corporation CK804 Ethernet Controller (rev a3)
00:0b.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3)
my home lan looks like that. I have router with build-in switch
100Mbitsps. Offcourse CK804 eth controller is 1000Mbitsps. To wan i
should reach 4,5Mbitsps and it was. Every things was fine until 23
december 2008 :D then my speed from ubuntu 8.1 down to max 2,7Mbitsps...
Some times was better some time worst. So i change MTU by hand. i set it
to 1500. And now is ok.
but there are some other problems, i think connected with driver of
CK804 Eth. for example releasing IP addresses getting from DHCP.
*before sting manulay MTU*
