No ethernet light = dead port

My 2 day old media PC started getting slow downloads - but fine in safe mode.

Decided to just N&P as some driver or service must have been interfering. Anyway just done the drivers and still no network.

Its in device manager but its acting as if a faulty switch port/cable as there is no ethernet activity light at all.

The same cable/port works fine on my laptop. Tried different cables, ports so its not that. Tried a different driver and reset bios.

End of the day - no ethernet activity light = dead port?
 
Are you getting connectivity/data lights in safe mode?

The easiest thing to do is swap in a PCI or USB based NIC. Since the rig is 2 days old it's real possible to have a hardware failure. The first week of burn-in will usually kill marginal hardware.

Is it a home built or OEM? If home built check the BIOS to ensure the NIC is enabled. A reset will usually do that if OEM.
 
Its a Gigabyte AM1M-S2H and its enabled in bios.

Was working full speed in safe mode before but about a tenth of the speed in normal mode.

After reinstall I get nothing now, normal or safe mode. Also no activity light which should be present even when the machine is powered off amiright? So thats hardware level not even driver/OS.


And its not got PCI :rolleyes: its pciex1 and pciex4 lol.
 
Some rigs show a connectivity/data light with the unit powered off but not all.

You can buy a PCIe NIC or an USB based unit. Don't beat your head against the wall until you try a substitute NIC. Then it's panic time!
 
A USB one might be pretty handy for troubleshooting or when dealing with troublesome problems like mine I suppose.

Never seen it not power up the port from Ethernet though
 
I have two laptops on my bench. An older Dell E1505 that doesn't set the connectivity LED powered off and a HP Mini 5102 that does.

If it was my rig I'd buy a PCIe based NIC before I tried anything else at this point.

As a matter of fact I'm buying one to throw in my bag of tricks because of this post. I'm seeing less PCI slots in newer PC's.

Oh yeah, what happens when you ping 127.0.0.1? If that fails and you are sure about the driver that would point to a faulty NIC or a corrupt IP stack.

Good luck!

You gotta be kidding me...
 
Well for no reason its started working again - also turns out if I use the latest AMD APU drivers, beta or stable it kills network speeds to about 3mbps. Using the supplied disk I can get 75mbps (fibre speed test)

I like to have the latest drivers though :mad:

Will keep an eye on it...
 
Don't forget a Linux boot to test such things in the future. That'll bypass any Windows specific issues.
 
It seems the freakiest issues are with our own rigs.

Look real close at the connectors pins. Maybe they were a bit mangled.
