Cannot connect desktop to internet after power failure?

By faidelano ·
The power died for a second and afterwards the internet no longer worked on my desktop computer.
The internet works fine on all wireless devices and there is nothing wrong with the Ethernet cable.
I have restarted the router and modem multiple times, checked the drivers and done many many different troubleshooting.
It seems as though the internet is fine but my computer is not picked up by my modem since the little computer light won't go on when I plug my computer into the modem.

My computer info:
Windows 7 Home Premium
Manufacturer: Acer
Model: Aspire X1920
Processor: Pentium(R) Dual-Core CPU E6600 @ 3,06Hz 3.07 GHz
Installed memory (RAM): 4.00 GB
System type: 64-bit Operating System


And this is what happens when I do the IP config thing in CM

Windows IP Configuration

Host Name . . . . . . . . . . . . : Angelique-PC
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No

Now in case you can't already tell I am really bad with computers so any help at all would be much appreciated since I am becoming really frustrated.Thank you!

Ethernet port failed on your PC

by robo_dev In reply to Cannot connect desktop to ...

Assuming that:

Some other PC plugged into your modem, using the same cable does work, then most likely the power outage also caused a power surge that killed your ethernet adapter.

The Ethernet adapter is part of the motherboard on most systems, so if yours is still under warranty, you need a new motherboard.

Acer most likely has some sort of a diagnostic utility program that can test things like the Ethernet port to confirm that this is the problem. The diag program either came with the PC or can be downloaded from Acer.

Assuming your PC has a free PCIe slot, the quickest/cheapest fix is to buy a cheap $10 PCIe Ethernet adapter, install that in your PC, and use that instead of the port on the motherboard. There are also USB-Ethernet adapters if you do not have a free expansion slot.
