Broken LAN controller?

[djsprinkle]

Okay I'm having a major problem with my computer. I built a new Z68 rig about a month ago and everything has been fine until today, I lost all network connections. I think I narrowed the problem down to the LAN controller on the motherboard but I'm not sure. I have tested and confirmed that my wired connection is good, the same modem and Ethernet cables work on other computers but when plugged into my Asus P8Z68-V, I am unable to establish a connection. The Windows troubleshooting diagnostic says it's a problem with the modem (it always says that) but other computers work fine with the same connection so obviously that's not the case.

I tried re-installing the LAN controller drivers and booting from Linux instead of Windows, but still have the same problem. I really want to avoid an RMA for obvious reasons, any other ideas?

are there any lights on the network card when connected to the router?

is the network adapter enabled in the BIOS?

Yes, the controller is enabled in BIOS and there is a light when the ethernet cable is plugged in.

Well I spent an hour on the phone with tech support from my ISP and tried a new Windows install as well, still no luck. I submitted a support ticket to ASUS and they already responded, directing me to the RMA department... not looking good.

if the device in question does not show up in the Device Manager, it does not look good.

should the device show in the Device Manager and has drivers installed, does it have an IP assigned?

It does show up in device manager. It has an IP assigned but not the right one (it should be the IP of the router right?) The tech support for my ISP was confused because the IP it has was one that usually appears when there is a problem with the modem/router/Ethernet cable, but clearly it's none of those.

what happens when you assign a static IP to your computer?

Well I bought a PCI Lan card and it installed and works without a hitch so the problem was the onboard controller on my Asus P8Z68-V failed after less than two months.
