net connection not working after power outage

May 17, 2010 at 07:00:46
Specs: Windows XP SP3, Intel P4 2.8GHz/2GB
i recently had a brief power outage and one of my computers restarted as a result.

since then i have no working network connection- i was accessing the Internet and home network drives the day before on the computer, so i think the power outage may be the culprit.

i have an IP address, but i can't even ping my home router. there are no indications in Windows of a faulty network connection- everything looks as it should until i try to access Internet- i will sometimes get the dialogue which indicates that there is no network connection available, and gives the options of retrying or working offline. all of my other PCs (connected to my home router) are able to access the Internet and network shares with no issues.

i've tried doing a couple of checkdisks on the system drive, and even used system restore to restore the system files back to the date before i discovered the issue, but no go.

any suggestions would be greatly appreciated.

Open a command prompt window (Start >> Run >> type cmd and hit Enter) and type the following command:

ipconfig /all

If you have another computer (or other computers) in your home LAN, do the same and compare the output. The only thing that should be different is the actual IP address. Subnet Mask, DNS, and Default Gateway IP's should all be the same.

If you don't have another, copy and paste the ouput here.

Check in Device Manager and ensure the device is working properly.

You saying you checked when it was requested you post the ipconfig /all for review doesn't help you or us address your issue.

What may look fine to you may not look fine to us.

If you are serious about getting support you need to follow the requested directions. Thanks

i have checked device manager and the NIC status indicates it is working properly.

i have compared the output of ipconfg /all to another computer on my home lan and both are the same except for the computer's IP address.

here's the output:

Thanks for the ipconfig.

You have a static ip address which does not mean your nic works. If you were set to dhcp and got an ip then you know your nic works.

"i can't even ping my home router"
and
"get the dialogue which indicates that there is no network connection available.

I would suggest the following order
swap the cable with a known good one
replace the nic

My guess is your nic died.

If builtin make sure in the bios its enabled.

well this is bizarre... i tried accessing the Internet again with the faulty connection (in Safe mode and normal start up) and no change, so i decided to plug in a USB wireless network adapter to see if i could get network connectivity with it... the USB adapter worked fine, so i unplugged it, and tried the faulty connection again- it now works!

that's a new one...
