IP Settings Can't Be Changed After Manually Set

I do a lot of AV system programming, which generally involves having to set my IP address for either my Ethernet port or WiFi card to manual IPs temporarily. I am having an issue on a relatively clean install of Win8 Pro that after I change my IP, when I go back into TCP/IP v4 to change it back to DHCP, it is already set to automatic... but if I right click on the connection icon and go to Status, it still has the static address. I tried to set it to another manual address and to hopefully go back in to revert, but that doesn't work.

The ONLY thing that seems to work is removing the NIC from Device Manager and then re-scanning for hardware changes where it will be automatically detected with DHCP enabled by default.

WiFi card is Intel Centrino Ultimate-N 6300 AGN.

Ethernet NIC is a Broadcom NetXtreme 57??.

I've got the latest available drivers, and using generic ones doesn't help. It's also on both NICs so I don't it is a driver issue.

Ideas?

I believe I tried that and it did not work... perhaps because that only releases the IP when obtained by DHCP? My problem is I can't switch it back to DHCP. And why, when I go back to IP settings, isn't the currently assigned static address populated in the number fields? It is pre-set to DHCP as if that is the current setting, but it is not. If I leave it to DHCP and click OK, but go back to Status, the static IP that I originally set is still there.

It is my own laptop. The Windows 8 Pro x64 comes from my TechNet subscription and is the final RTM build.

Nope. No Domain. No Policy. It is for the most part a clean install of Windows 8 Pro.

This is wear , all true I'm not surprise I have few problem with network nic changing model by them self, and also virtual network nic that disappear after an update. This OS have some serious flaw for sure.

Hi all,

I posted a screencast of what I go through here: https://dl.dropbox.com/u/3071354/NIC%20IP%20Bug.swf

It looks like every time I change the IP and go back in, it adds another instance of the TCP/IP v4 stack, and starts listing multiple IPs for the same NIC.

It does this for both the Wireless and Wired adapters.

I am gonna post this in the TechNet Group as well and see what I can find out.

WEIRD.

From my point of view there is no default gateway being defined and the IP's being used seem to be in a different subnet than the router is using but that is hard to tell because nothing is showing a normal default gateway like 192.168.0.1.

This may be confusing the adaptor as to which network it's actually connected too.

If you need to connect to multiple subnets you should click "use the following address" to enabled then go into the Advanced IP settings tab and list the different, IP's, subnet's and gateways that you need to connect too.

You must be using a PCI wireless adaptor to get that 450Mbps speed.

It's got nothing to do with there being no default gateway. I can punch in the same numbers as what the DHCP server hands out and then go back in and still can't change it back to DHCP.

You only need a default gateway when your NIC needs to request sites on a different subnet, which isn't the case here. I am assigning something like 192.168.0.1 and only trying to communicate with addresses on that subnet, so a gateway is not needed.

The problem doesn't exist in Windows 7.

So the only problem is that IPv4 interface won't allow you to choose DHCP anymore.

Here is what I get when I Google this problem.

For Windows 7 network types, the secret lies in the GATEWAY entry. Any network you connect on that doesn't have a DEFAULT GATEWAY provided with, becomes PUBLIC and you cannot change it's type.

So in with Windows 8 you need to have a Default Gateway defined in order to change the network type to "Private" which then should allow you to enable DHCP again.

Those are different things. The Private/Public setting is whether shared folders are visible or not. The Gateway is only needed to get outside of the NIC's IP. It's not required.

As I've said before, I could be disconnected from the Internet and only need to communicate with a handful of IPs on a single subnet. Even if I had an 8-port switch and no router, there is no default gateway in this scenario and I would still have the same problem of not being able to switch back to DHCP mode on that NIC.

In other setups that I've done for years, I would have my wireless NIC connected to a WiFi network with Internet, where a default gateway and DNS are both defined, and my wired NIC connected to some static IPs with no router on a switch. This setup allows my PC to talk to both networks with no problems, given the two NICs are two different subnets.

I really appreciate the input, but trust me, I know what I am talking about here. I've got 20 years of Windows networking experience. The intention of my post was to identify a potential Windows 8 bug and see if anyone else is having the same issue. I'll do another screen cast later this weekend to show the behavior as it is supposed to be on Windows 7.

Still haven't figured this out. It doesn't seem to be an issue with drivers as it happens across all NICs. Settings and provider order match my desktop, and it doesn't happen on that.

I guess clean install is the next step, but I REALLY don't want to do that.

Thanks!

Same issue- looking for answers

I have the SAME problem and wondered if you ever found a solution. I frequently change my ip address b/c I connect to devices at various sites on different subnets. They seem to pile up even when I disable/enable the adapter. Let me know if you found anything about this issue.
Thanks

When you setup the IP addresses for the networks you should allways set the following:

- IP address:
- Subnet Mask
- Default Gateway

DNS isnt required but if you can get a hold of the DNS ips from your router then please set that up as well.
