Local access only ... need some serious help

**mt103** · 07 Mar 2012

Hello all,

i have been battling this issue for the past 2 days, thus far i am not winning ...

out of the blue my wired network went to local access only. wireless devices work fine, plugging ethernet into another machine works fine as well. i have attempted multiple suggested fixes with no positive results. some details about the problem:

when testing with ipconfig i get assigned a default IP (162.xxx) and no default gateway

i can ping local (127.xxx) but not router or beyond

tried:
windows troubleshooting
safe mode with connectivity
reinstalling drivers
resetting NIC
updating all drivers
system restore
flashing BIOS

nothing works and i am getting quite desperate since i kinda like this machine. i am totally lost, please help !

hello mt103, and welcome to Vista Forums.

Try this tutorial out and see if it helps at all: Internet Troubleshooting Guide - Windows 7 Forums - created by Dinesh

Failing all of that, try downloading the most recent driver for wireless lan from your computer's manufacturer's website, uninstall your current one, and install the new one.

Let me know how it goes.

Thank you for the reply Dust, i have indeed attempted the troubleshooting by Dinesh ... unfortunately no luck there. I tried numerous fixes proposed, included those on forums here.
as for drivers, i have updated all drivers including chipset but the problem persists. Also, it is the wired connection that is troubled.

is there anything i can do to try and diagnose/fix it before i pop in a new NIC ?

thanks a lot, regards

Hello mt103 and welcome to the forums

In addition to the excellent advice mt103 is giving you, I would suggest trying the attached batch file. Download and run it please.

Here's the code, should you want to inspect it:

Code:

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

This will fully reset your internet connection back to the default settings

Thanks for the suggestion Tom,

i ran the code. however, ipconfig /renew gets me an error stating cannot contact dhcp server (dhcp client is running, dhcp server on router has no problems).

newsflash: tried popping a brand new NIC, the system won't even recognize it ... is my motherboard failing ?

Hello mt103,

Hmm, well at least it's another clue

Have you got a dynamic or a static IP?

Tom

**tom982** · 07 Mar 2012

Can you run an ipconfig /all command and post the results here please?

Tom

**mt103** · 07 Mar 2012

dynamic IP

as for ipconfig, it would take me a few minutes to transfer the output between the machines, but in short i get the 169.xxx ip and no default gateway.

post to follow with the actual output.

Hello mt103,

Hmm, there's definitely something wrong with your DHCP. For a start, there doesn't seem to be a default gateway, and secondly, your IP address indicates that your computer is unable to get one from your router (it starts with 169.254 which means it's a privately allocated IP).

Can you follow the steps outlined in this tutorial please:
