IP address won't change.
« on: February 09, 2009, 10:32:17 AM »
Good day Shane!

 Hope all is well.

 I have a DELL PC given to me by a friend and it's fairly new.Im using a Netgear Wgr614 v6 router and a Westell 6100 modem.My pc is getting 192.168.0.12 IP address wherein it should be getting a 192.168.1.x IP behind the router.I've check TCP/IP properties,reset the modem, and even assigned static IP on the pc but still it shows 192.168.0.12 IP.Is there something wrong with the NIC or is it my computers motherboard?

Hope you can reply asap! thanks!

ok first thing to check, what is the WAN ip address of the netgear getting?
is it a internet IP or another local ip?

The Netgear is getting WAN IP: 192.168.1.47.

192.168.0.12 would be the pc's Local IP address.

My cousins laptop works on this Netgear router before.It's getting 10.0.0.1 IP address and router's WAN IP is 192.168.1.46.But this I believe because of the Netgear's capability of changing it's own Local IP upon detecting a conflict from the WAN side.My DELL pc should get 192.168.1.x or 10.0.0.x IP.

Is there aby possible configuration done on the DELL pc before that i won't get a valid IP address being given by a DHCP server? Even I set static IP on it and unplug the modem from the back of the router still same result.I have a feeling it's something on the pc software.

ok so the internet IP your getting on this page
http://www.pcwintech.com/files/screenshots/netgear-wgr614_v6/000.png

is 192.168.1.46, this is a local IP which means the westell is also a router.

what info do you have on the LAN ip page?

Yes Westell is also a router,wired router.

Default IP: 192.168.1.1.
Starting IP through DHCP: 192.168.1.46.

Netgear default IP: 192.168.1.1
Starting IP: 192.168.1.2

I just tried 15 min. ago a laptop(hardwired).I'm able to get 10.0.0.2 IP and I'm online.As I've said Netgear router is capable of changing it's LAN IP it's now 10.0.0.1 and router status on WAN is 192.168.1.46.

I hardwired the DELL pc on ethernet port #2 and still getting 192.168.0.12 IP.Im afraid there might be some software issue on the DELL pc.But I want to know how this might be possible.Just curious why sir.

ok with both routers using the same IP range this can cause problems.

So on the netgear, change the LAN ip setup and the dhcp to use 192.168.2.1 instead of .1.1

Also with windows we can do a few things there. First make sure it is set to dhcp and not static. Then try these commands

this is from a bat file I use

ECHO Releasing IP Information...
%systemroot%\system32\ipconfig /release

ECHO Purging the DNS resolver cache...
%systemroot%\system32\ipconfig /flushdns

ECHO Renewing IP Information...
%systemroot%\system32\ipconfig /renew

ECHO Refreshing all DHCP leases and re-registering DNS names...
%systemroot%\system32\ipconfig /registerdns

and see what IP you get after you change the lan ip and run those commands.

  It worked!!!

  My DELL pc is now getting 10.0.0.3 IP address and it's online.What do you think it has caused the problem? Is it possible corrupted TCP/IP stack? I called one of my friends and he told me that this pc might be configured to static IP(192.168.0.12) before and file sharing is ON.He said that the NIC got defective and was removed from the PCI slot without setting it back to DCHP that why it won't change the IP address.Is that true sir?

I have seen that happen
« Reply #7 on: February 09, 2009, 01:47:04 PM »
I have seen that happen before. but the ip information is stored in the registry and can be removed.

take a look here

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces\

each folder under here is a network connection. You'll find the old and current network setups there.

Worse case is you just need to remove the corrupted interface from the registry, uninstall the nic card from the device manager first (make sure to go to view and show hidden devices to show hardware that's installed but not currently present)

uninstall it from there. Remove the interface from the reg (make a backup first by exporting what your about to remove)

and rebooting. When the nic card is back in the system, or already is then windows will reinstall it and also create the reg keys new.

At that point you should be good to go. The IP info like I said is stored in windows in the reg. not the nic card itself.

If its something your not
« Reply #11 on: February 09, 2009, 02:13:12 PM »
If its something your not comfortable with you shouldn't ever mess with the reg. One wrong key gets moved or deleted you can kill the whole operating system. The registry is the brain hive of windows. No disrespect, but if a computer rookie gets in there and starts doing things you can count on a reinstall in your future LOL

I had a customer find that out the hard way :-)

But for what you want to do it is pretty safe if the right steps are followed.
But you said it was working now, if it is working you shouldn't need to remove anything.
