Unidentified Public Network - Invalid IP Address
Aug 31, 2009
I have been using Windows 7 for about a month now and two days ago i started to have network problems.
I cannot connect to the Internet or my network and keep getting messages saying that the network cable is unplugged when it is not. After a while i was able to get a different message and the computer connects to an unidentified network and when i troubleshoot this it tells me i have an invalid IP address.
I know the problem has got nothing to do with the hardware or my Internet. I have tried 2 other router's & another modem with different Ethernet cables with no luck but my network/Internet is working fine on my laptop which is also Windows 7.

I'm setting up a new computer and having problems getting on the Internet. The connection worked at first but was very slow. I changed Ethernet cables to see if that was the problem and now have nothing.
The error that I am getting is:
"Local Area Connection" doesn't have a valid IP Configuration
I also have Norton Internet Security running which could be part of the problem.

Home network with Wifi and ethernet. Using 3x Notebooks and 3x workstations. One of the workstations (W7 ultimate) keeps changing between Public and Home. When this happens, the internet connection dies. I cannot see other workstations either when on public network. Workstation using wifi. Does the same on cable. When it changes to Public, it disconnects from the internet and I cannot get to the router even though it has the workstation has an IP(DHCP or static). Default gateway and subnet is correct. TCP v4 is being used and nothing else is enabled.
Why is this happening?
- I have tried DHCP as well as Static addresses
- Reconfigured NIC(Netgear WG311T), uninstalled and reinstalled it.
- Removed Wifi connection and re-added it.
- Changed auth type, encryption type and keys to connection
Have I covered everything? The only thing different is that I installed a new router - Duo Plus 300wr. It cannot be the router because all the other notebooks connect to it wireless and so does my iPad, Android device and tablet...so it rules that out?

I posted a reply on a similar topic but figured I'd start a new thread even though it seems this has been discussed a lot.I have a verizon wireless cell access point I connect a w7hp pc to it and set it as a home network. I also have a nic in the same w7hp box connected to a local 10/100/1g switch with a bunch of other stuff on it, an xp pc, a ps3, a directtv dvr, and a majicjack. That's my home LAN.I'm letting the w7hp machine do the dhcp as part of internet connection sharing which mostly works fine. I had to hard set an ip address for the dvr. There's even a registry entry that you can control the dhcp local subnet.What I'm finding is that with windows 7 home premium even though you can share an internet connection there is no way to change an independent home LAN network to be a "home" location.
Because w7hp decides the home LAN is "unidentified" it won't let you change the type and it's stuck as a "public" network. So none of your home computers can talk to the windows 7 computer. They can use the internet but that's about it.here's a lot of fixes floating around but none seem to correctly fix the problem.It's not a problem if you have w7pro because you can edit the security settings forunidentified networks and let the admin change them. But I can't even find the security registry entries in w7hp.

I had problems with my computer not connecting to the network sometimes after restarting my computer. That was usually fixed by simply unplugging and replugging into my outlet. I have a hard wire connection and my ethernet cable gets plugged into the wall and connects to the modem/router (whichever it is) from there. After I reset my computer this morning though, my computer has absolutely refused to connect to the network. I've tried resetting the router/modem and unplugging and replugging in my Ethernet cable. I noticed however in the network center it showed me connected to Network 8 (my standard home connection) for a few seconds but then it changes to unidentified public network and breaks connection to the Internet. Wireless is working fine and I'm infact typing all this on my iPhone 4.

I was on my laptop on Friday and the internet would connect when I turned on my laptop. So I just thought I needed to retype the security key. Nope. So after that I reboted my router. (Sorry for my horrible spelling). That didn't work either. So I came here and saw a number of people had the same problem. I tried every thing pluging my laptop into the router, netsh winsock reset, disable and enable the network.

As per a lot of other people on here, I'm having issues with connecting my desktop PC to my BigPond router. It will connect via wireless (have an installed D-Link DWA525 wireless card) but will not connect via LAN.I've changed the IP, DNS and Default gateways to the same as the other working PC's in the house, but still no luck. The mobo uses Realtek GBE Family PCI-E controllers, but for some reason it won't move off 10Mbps (even when I try to tell it to change this).I have tried new drivers, and have tried uninstalling drivers and letting windows install its own. None have worked. I've disabled V6, didn't work.My IPCONFIG ALL shows up the following: [code]

I have done things such as remove Bonjour, Stop services from Apple and Adobe, manually set my I.P. address, ping 127.0.0.1 with success, updated drivers, removed Microsoft office. Just trust me a HUGE list of things and none of them have worked. This all started when I had to restart my PC. My PC starts says the network is Unidentified, the repair tries to restart it, then suggest I restart my router, then says "Local area network is a invalid IP configuration."
We currently have 2 laptops (One with Vista the other with 7) and a desktop(XP) running on the network fine (Mine usually being the second desktop):
Windows 7 x32
4GB RAM
500GB HD
AMD Phenom II Black Edition 3.1Ghz
Nvidia 9800GT

Above is the error that comes up after I troubleshoot this issue. okay so to start off let me say the things I have done.
1. I have restarted my computer multiple times and restarted the modem and router.
2. I've checked my services to make sure that that weird code is not there and it was not.
This problem just came up recently and had no issues with it before and this computer has been running for over a year.

I just switched to AT&T U-Verse for my internet, and they provided me with the router and everything needed for wireless internet. My work computer, running Vista, connects with no problems at all, just type in the password and go. My iPhone also connects with no problem once the password it typed in. I tried to connect my PC running 7 wirelessly, and an invalid IP Address message comes up. I tried connecting it to the router with an ethernet wire, and the same message came up. Also, it says that I'm connected to an "Unidentified Network." I've connected my PC to many different wifi connections over the last couple of years, and this is the first time I've ever had this problem.

I have two network cards in my PC. One of them connects to the internet while the other connects to my home network.
The issue is enabling public folders for the home network in "Network and Sharing Center" enables public folders for the public network also. In other words Windows grants permission to people on the internet to access my c:usersPublic folder.
Disabling public folders under public network settings disables public folders for the home network also, preventing people on my local area network from accessing my PC.

When connecting via an ethernet cable to a parent's modem, my laptop claims that Local Area Connection is unable to connect due to an invalid IP address. I've looked at many forums, but no single solution seems present and no one shares the same specs or IP config results with me.
Specs: Laptop: Samsung Q430
OS: Windows 7 Home Premium 64bit
CPU: Intel Core i5 M 450 2.4 GHz

Today, I managed to redecorate my bedroom; where my computer sat on top of a shaky, wooden desk. That desk is now gone, caput, and replaced by a much bigger, sturdier and prettier glass replacement.Before I dissasembled the computer to re-decorate, I was able to browse the internet at ease. There were no problems at all...However, after the new desk was setup - and all wires replaced in their correct slots, I find that I am unable to connect to the internet, or even the house's network! For the past year, I have been wired to the router using a RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC. It was plugged into an extension cord, in my room, into the Ethernet port in the back of my computer. Downstairs, it's twin was situated no less than 2 feet away from the router - plugged into the first port.Now, when I boot up the computer, the network notification presents the following message: "Unidentified Network. No network access", and sometimes presents a yellow ! next to it. So, I am reduced to typing on my mother's laptop - which has no problems connecting to the network.I am able to use the ipconfig /release command, but unable to use the /renew - it hangs in the command prompt, then tells me that the DHCP server cannot be located. The IP, beforehand, was reverted to 169.254.223.117 - before all of this, I was 192.168.0.5?

My LAN (local area connection) is automatically on a Public network, I'm not sure why or if its always been like this. My Broadband is on home. I cant change the LAN to home. A message popped up and said something along the lines of "this network has too many internet connections".
I'm wondering what it means if my unidentified network is public and if there is anyway to change it to home?

I am having a problem connecting to the internet in a public library where all other laptop users are connecting successfully. The curious part of the connectivity issue (to me, anyway) is that according to my computer I AM connected to the network. I have provided some screen caps of the issue (links below), and tried to run the Intel ProSet Wireless Tools diagnostic to troubleshoot the problem of connectivity. The test run by my computer indicated that my Ping Test failed Response: Default Gateway, DHCP server No Response.

Under "Advanced sharing settings", one can really turn off a lot of network sharing features to secure a computer.The "Public folder sharing" switch allows one to turn off Public folder sharing, but people logged on to "this" computer can still access these folders. Does anyone know if this means *remote* login? If so, is there a way to deactivate this so that it is only accessible at the "console"? And by Public folder, does that mean a folder that is user-specific (and controlled by owning user), but open to the public? Or does it mean a file space "commons", accessible and controlled by all users?The "Password protected sharing" switch allows one to restrict access to the computer to only those who have an account and password on the computer. Again, is there a way to ensure that access is only possible from the console?

So I have fibre optic broadband and I connect my PC and Xbox 360 together through my PC motherboard LAN connections.To explain what I have done is I have two LAN connections on my EvGA 680i motherboard and I have bridged out these two ports because I find it is is easier connecting the Xbox this way as I don't have to deal with the firewall issues and programme each file to access it and it is just smoother with no dropouts.The problem that I have though is as soon as I start up the Xbox 360 then my PC and any other laptop has this issue.Firstly the two laptops connect wirelessly.As soon as the Xbox fires up firstly it switches on my partners HP DV6000 laptop and this might be because it is a media laptop and has an infra red remote which perhaps frequencies are crossing. I can live with this.The issue is the network.Both my PC and the laptops automatically switch from a homegroup to a public network.
My PC is fine if I reboot, it will revert back to the homegroup but my partners laptop will not. It stays on this public network and so she can't access the internet.I have tried changing and managed to change back to a homegroup but it is confused in that it does not know which homegroup to connect to.I have typed in the WPA code but it does not appear to recognise this as our network.Is it because I have bridged the LAN ports and it is confusing Windows?All are using Windows 7. PC and HP laptop are Ultimate and other laptop is Professional.

Since xp the same ol' same ol'. Why after trouble shooting and getting access to my network folders does windows ALWAYS revert back to inaccessibility? You get it working for a short time and then it goes back to not being able to transfer simple files. This has been driving me nuts for years.
Two os's Windows 7 64 to and from 32bit could transfer files for about a week.

I can�t get online. Icon in taskbar says I don�t have a network connection. Upon exploring, I find that Windows 7 Pro has me setup for a �public network��which has a yellow exclamation mark on the left side between my PC and the network, and a red X on the right side between the network and the Internet.
DETAILS:Dell desktop PC. Was running Windows 7 Home, now running Windows 7 Pro (full install; not upgrade). I had a malware problem (images on webpages and links, etc. were not visible to me) with W7Home; cleaned it and went to W7Pro. However, now I have this whole new and far worse problem with W7Pro. (See �problem� above.) NOTE: I am the only person in my house and the only person using the computer. So I never had it set up for a network. I only own the desktop PC and don�t need a network. The �network� that is now set up on my computer was set up by W7Pro by itself as part of the problem. My IP is not static so I can�t input my IP manually�it�s set to automatically detect. Called cable modem service provider; they made the assumption my operating system came with my PC and told me to call Dell for support. When I explained my OS didn�t come with the PC, they then said �You need to talk to Microsoft.� Uh---no. The cable modem service provider said their server is talking to my PC�my PC is unable to get to them. (Makes sense, as that matches the pictures I�m seeing with the exclamation mark and red X.)

I just moved to a new home, and i cannot connect to my local LAN ! I am on a Mac right now ( arghh ) and the Internet works fine on this one.
I am using a cable to a router, wich is connected to a modem. The router is fairly old but has always worked fine ( using a direct cable doesnt work aswell ). Windows 7 says it is connected to a 'Unidentified Network'. The ipv4 settings for the adapter are; Automatic ip/dhcp.
ipconfig gives an ipv6 address. The automatically generated ip is: 169.254.241.20. There is nothing at Default Gateway. The driver settings are correct, as far as i believe. I downloaded the latest x64 Windows 7 marvell yukon drivers.
I disabled sleep mode on my pc. I don't have the Bonjour service running. On the Mac, i only had to enable DHCP and it recognized the network correctly. These are the ip's that it got:
ip: 83.87.107.135
subnet: 255.255.248.0
router: 83.87.104.1
This is getting frustrating since i cannot see where the problem could be.
here are my specs;
Asus p5w DH Deluxe
win 7 ( 7600 )
q6600
2 integrated network adapters on the mobo: Marvell Yukon 88E8053 pci-e Gigabit Ethernet Controller
