Asrock H97M Pro4 no internet connection?

Hi, I've recently built a new computer (Win7-64) and everything was fine, had internet connection etc. I came back yesterday morning & internet connection was suddenly gone? Modem/router had disconnected itself, so I reconnected and now I have internet wi-fi ok but still no broadband on my desktop PC?

Diagnostics suggests there is no link to the network adapter, ie the ethernet cable is faulty? So I tried another cable and still the same problem?

I'm pretty sure the motherboard's ethernet port is fine (mobo is brand new). It doesn't light up, but when I run the LAC "Identify Adaptor" diagnostic it starts blinking, so I assume it is ok?

Would a faulty cable cause the port not to light up? It could be that both my ethernet cables are faulty perhaps? Should I buy a 3rd one & try it?

Also in Device Manager nothing is highlighted, the network adapter & drivers are installed ok etc.

What should I do? I'm tearing my hair out with this! It's a brand new build & was performing excellently until yesterday!?

Thanks in advance -- :)

I would try connecting the system to another device other than the modem/router to rule them out as the issue. By the sound of it though, I would guess the fuse on the LAN port has blown (power surge through the LAN cable).

Don't do a fresh install. Sounds like your modem went belly up.

Test with another to verify.

OK will do, I'm borrowing a friend's modem tomorrow. I appreciate your responses, you guys. I'll post back my results.

I'm hoping it's the modem? Because the motherboard is brand new! Anyway I suppose I could just add a PCI network card if it's the motherboard's LAN port, right?

Anyway try a different modem first... Thanks again! :)

The LEDs are Activity LED and Connection LED, both require a signal so no, if the modem's LAN port is toast there wouldn't be any LEDs lighting up.
