Let's give this a whirl...

CMD (Run as Administrator)

netsh int ip reset reset.txt
[Enter]
netsh winsock reset
[Enter]
netsh advfirewall reset
[Enter]

Reboot. Let us know what happens.

Oh, if you've tweaked your firewall for whatever reason, you might want to peruse it and take note of what all you've done before executing that last command.

Do a System Restore to an earlier date when it was working.
(Or, restore your latest system image backup.)

do you have more than one network adapter in your network connections? You are setting STATIC IP info right, no dynamic?

ya i do have an usb wifi adapter sharing the connection.., but it didn't used to happen as long i used it in my old pc with win XP,.happened ever since i upgraded my motherboard with win 7...its not a hardware problem right? :banghead:

So does it happen without the adapter? Also try removing the gateway IP from the the wifi adapter settings. Also, to clarify, you're talking about the onboard NIC right?

did that still same....yup its nic

heres the ntework config:

time to dive into the registry. Set your IPs like they should be, Go to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Paramters\Interfaces. Find the interface key in question, take a screenshot, reboot, take another screen shot of the same thing, let's compare the differences. Something, program, is overwriting your settings.

well dat seems to have no differences after restart :O

This is wat happens after restart....any clues ?!?

 

[event3horizon]

so hold on.. are trying to use static ip or dhcp on your wired nic?

 

[ayan4u]

ok the second key was changed

 

[event3horizon]

Ok try this. First create a system restore point in case anything goes wrong.

1) Download your latest NIC driver to a place you'll remember

2) delete the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\Config

3) Uninstall your NIC from device manager, check the delete driver button if available

4) Reboot, have windows detect your NIC, and reinstall the NIC driver with the one you downloaded.

well dat didn't work either ....after upgrading to win 10, it initially did't save the addresses everytime i put em ,later it showed up an ip address conflict error....after reinstalling the wifi drivers everything worked but its unable to connect any network to it even with firewall off,so is it the ip conflict causing d prob ?!?.....

 

[event3horizon]

you upgraded to 10?

 

[ayan4u]

you upgraded to 10?

yah dat was for few hours and then reverted back,.10 sucked

 

[event3horizon]

Gee well, if it was still happening in windows 10, then you may have NIC hardware issue, or there is SOME third party program overwriting your IP config.

 

[AddRAM]

Yep, Something is changing those settings, that`s bad.

Backup your data, re install windows.

Why do you have a usb wireless device "sharing" the connection ? (As you say)

Get that out of there, there is no need for it.


Also, there should be no ip address conflicts, if the settings are right, windows finds an ip address everytime you start the PC, and from then on usually uses that same address everyday.
