I have been running the same setup in my house for the last year - 4 Ubuntu computers (all the exact same, with same PCI cards, gfx cards, etc...)
connected to a Belkin WirelessG router.. My setup during this time has been:
DSL Modem -> Belkin WirelessG - >PC's
Pretty simple, and has worked well... But now I have been working on upgrading to a gigabit setup. The setup I want should be:
DSL Modem -> LMCE Core external NIC / LMCE Internal NIC-> D-Link Gigabit switch ->PC's, MD's and XBox 360
This sounds simple as well, but has turned out to be a nightmare.
Plugging my only wired Ubuntu PC into the gigabit switch yields nothing.. The networking Icon shows as disconnected. (but it has absolutely no problem connecting to the Belkin router) Doing reboots, enabling/disabling the network interface does nothing either. Its like its not even being seen by LMCE. In fact, even the light on the gigabit switch does not come on showing a connection on that port (though it blinks once in a while). If I boot the PC into Windows (it is a dual boot setup), then Window's has absolutely no problem connecting to the core.
So why am I haveing such a problem getting Ubuntu to connect to LMCE? I know the NIC and wiring are good, because windows connects to the core, and I also know that the NIC works in Ubuntu as I have used it for the last year, trouble free. The NIC is a gigabit card, and the gigabit switch supports 10/100 even if the card wasn't gigabit, so I'm highly doubting that it is a hardware issue. In fact, after 3 days of total frustration, I bought a brand new gigabit switch and ended up with the same results.
I guess its looking like the problem is in my Ubuntu box. Does anyone know what I should check next? Is there a way to reset my Ubuntu networking back to defaults? (I never changed anything, but the way it is acting makes me think something has changed somewhere - maybe a config file??)
