Hello,
I hope you can help me out diagnose a strange and annoying problem with my network.
My home network is based on TP-Link 1043nd router (running dd-wrt) set as dhcp router and wifi ap (looking to move the dhcp server to the homeserver). Hooked to it are several machines and a repotec G3800gc swich. My main machine and homserver are connected to the swich. Both are running 12.04 precise respectivly amd64 desktop and i386 server.
On both machines there is problem with connecting on gigabit speed.
I don't know how but after multiple ifup/down and so on the server managed to connect on gigabit, however I'm unable to do the same for the desktop machine. I tried setting it manually with ethtool, however there wasn't any results.
The equipment (router, swich, cables) are fine, and the Windows machines connect fine. Here's the output from my homeserver
And here is from the desktop machine
