Can't connect to internet after power cut.

[windranger]

I've got the power cut while PC was running (w7). After rebooting I'm not able to connect to the internet anymore.

In Device Manager, under Network Adapters there is a "Realtek PCIe GBE..." device properly installed.
But under Other Devices there are now more entries with exclamation mark:
- Network controller
- Multimedia controller
- PCI Communication controller
I tried updating the drivers, then deleting and reinstalling but no success so far. Still can't connect to the internet.
The browser can see the router, at 192.168.1.1
I don't know where the problem is.


I'm quite puzzled, I'd appreciate any ideas about what I could do.

Thanks

open up your command prompt and type ipconfig /all and post the results here

Have you got an onboard device that you aren't using? I.e have you got a network card and network inbuilt to the motherboard too? If so go into the bios and disable the onboard device.

Are you using a static ip address? Right now you dont have a default gateway so the computer doesnt know how to forward traffic to the internet.

If you are using a static ip address put in 192.168.1.1 for the default gateway

If you are using DHCP, your DHCP server doesnt look like its handing out a default gateway to DHCP clients.

No, I don't use a static IP.
So does this mean that the router has a problem? How should I repair the DHCP server..?

[GroundZero3]

What router do you have?

Webcaster V110 (NTT)

Do an ipconfig /release then an ipconfig /renew and then post your ipconfig /all

this will release the ip address you have, then try to renew it from the DHCP server

GroundZero3, thanks for the patience.

I've done that (pconfig /release -> an ipconfig /renew -> ipconfig /all) and here's the result; still can't connect to the net...

[GroundZero3]

Can you take a screen shot of your network settings.

also in your command prompt can you do a route print and post the results here

[windranger]

I could finally get connected to the net, hopefully not only temporarily!
What I did was enter the following instruction at the cmd prompt:
netsh int ipv6 reset reset.log

This reset the IPv and apparently solved the problem, hopefully not only temporarily.

Now the default gateway is not 0.0.0.0 any more.

Anyway, thanks a lot for your support.
