Lost Internet Connectivity; Connected To "Unidentified Network"
Feb 17, 2012
I had Windows 7 32-bit running on a Dell PC. About one week ago, I noticed Internet connectivity was gone and that there was "limited connectivity" as I was now connected to an "unidentified network". The other systems on the network are still connected and working perfect; the problem is isolated to this one system. The network uses a static IP scheme. "IPCONFIG /ALL" shows that the IP is assigned, is included on the correct subnet and has the correct gateway and DNS information. I've tried a host of solutions suggested on forums; from "route delete 0.0.0.0" to disabling my firewall to configuring for a dynamic IP. Nothing has worked. Reluctantly, I resorted to a fresh install as I began to worry that I may have picked something up. I completely wiped the hard drive and did a fresh Windows 7 32-bit installation all only to have the same problem. I assume that the NIC is functioning as it accepts all IP settings.
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 had my HTPC up and running last night, watched a movie, turned it off and went to bed. When I woke up this morning I found that I couldn't get any sound while playing videos through my web browsers, thinking it might be a video card issue I first checked some of my movies, but they also wouldn't play with sound so I deleted my nvidia files and reinstalled them. No luck, on one restart I lost my internet connection with my router. If I look inside the Buffalo's settings, I can see my HTPC's IP address (after running ipconfig /all on the htpc) I did a system restore but that didn't work. I even went so far as to do a clean install of Windows on the HTPC, but that also didn't work. I keep getting the yellow triangle and the message "unknown network" The HTPC tells me to check my router, which I have restarted a number of times unplugging the cable modem and the Buffalo. Turn on the cable modem get it online, then plug in the Buffalo, but nothing works. I have tried switching ethernet cables, ports, but no luck.

On the right hand side of the taskbar I have the icons for battery life, volume, internet connection, etc. When I used to put the mouse over the internet connection it would show me who I was connected too (SSID) , signal quality, and speed.I began having some issues so I had to remove my Netgear connection and then reconnect.Ever since I did this all that shows up now when I put the mouse over it is now only says: Netgear and Internet access.How do I get the information back. It shows up on my desktop, but not my laptop.
I'm running 7 Home Premium 64bit on an HP box we got about a month ago.
Lately, when I restart the system, I can't get any internet connection. I can access shares on my home network, so the nic is working and I'm getting an ip address from my router. If I disable and reenable the nic, the internet connection works again. I've tried disabling firewalls and things like that, but the only thing that fixes it is the disable/enable.
The network "troubleshooter" can't see anything wrong, and everything looks like it's configured properly, and nothing has been changes since the initial setup. It worked fine for a couple weeks and now doesn't.
Anyone seen this before? Hints? The disable/enable isn't a big deal but I know at some point I won't be home and my wife will have a problem and I'd rather not deal with that!
just upgraded my vista 64-bit install to win7 home prem 64-bit.
everything has been working great except for an internet/network issue. at random times, all of a sudden the icon in the tray gets that yellow exclamation point over it and says there's a network issue and no internet available. it's like that until i disable and re-enable the network adapter. there are other systems on the wired router and they're still working fine (vista and xp machines).
the strange thing is it *seems* to only do it when i start doing more than one thing at the same time. i.e. trying to watch Internet while playing an online game. or, downloading a pdf while streaming music. all of a sudden, all internet goes down (other computers still working fine though). once i reset the adapter, all is well.
We have 2 wireless laptops & 1 hard wired tower (all onWindows 7) in a home network. (All hardware are new this year) The laptops have intermittent internet connectivity yet do not lose the network connections. I have upgraded both the Motorola modem and Linksys router to Windows 7 but it did not resolve the issue.
My pc is connected a router with an ethernet cable. The router was reset and now the pc cannot connect to the internet.The message I get is,unidentified network access type No Internet access,work network connections,local area connections,we have rebooted, turned computer off then on, reset back to a previous time, changed the ethernet cable

When I try to connect to the internet, it just says "identifying" then says it is an "unidentified network". I've tried:
Resetting the modem Checked all cables Uninstalled and reinstalled the drivers Disabled & enabled the drivers It's set to automatically connect to DNS Updating the ethernet with the latest from Microsoft Ran ipconfig /release and renew Tried another modem and new cables Tried other houses with DSL & Cable internet
I installed a USB wireless device which worked when I tested it in wireless areas. But so far nothing has worked for the wired part. At one point before all this started, the internet worked intermittently and would work at other houses perfectly. So I assumed it was my modem or connection at my house. But then I plugged another PC into my modem and it worked instantly. So I know there is no physical problem with my connection, modem or cables.
I decided to just post this as a new thread, as it appears to be getting positive results for most people. I highly recommend it anyway, as you will eventually encounter this if you apply all of your updates.For those of you reporting problems with your network after updating MS Office or installing Adobe CS3..If you are having Internet connection problems related to "Unidentified Network" showing and the "!" over your NIC icon, then this should take care of it: [code] If you do, stop it and disable it. It is actually the Bonjour DNS Responder Service, and I believe it is the cause of the "Unidentified Network."The Unidentified Network disappeared after stopping this service and a quick disable/enable of the NIC, restoring Internet access.I Actually just rebooted, edited this post, and then re-enabled the offensive service to see what would happen...Immediately after enabling the NIC and this bastard service, the "Unidentified Network" returned...stopped it, disabled it, disable/enable NIC...Internet back up and running and no "Unidentified Network." (woot - woot!)
I experienced this in both build 7100 and 7127...I am running 7127 now x64 - and discovered this fix just last night...so far so good just rebooted and then edited this post...I believe this fix will solve 7100 build issues too; however..I have not tested 7100 again yet.I also re-enabled Win 7's Discovery Mapping services, but always leave IPv6 disabled just because I am not using it.another two reboots, and a hard disk addition, and no problems with the Internet! - If you tried another fix such as changing the address of your network adapter, under "Advanced" - this is not necessary...I set mine back to "Not Configured." Everything is working fine as long as the Bonjour service is not running.. [code]
I recently had a virus that I had removed, but now that its gone, I still cannot connect to the internet. It does not detect the ethernet cable when its plug in, as in the LED does not light up green.This is what CMD shows me when I do ipconfig /all Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation.
My computer had been working fine and while I was watching a movie on my computer the internet randomly gave out (wasn't streaming the movie or using the internet to watch it). Now I can't connect to the internet and it says that the network is Unidentified. I've tried a bunch of fixes such as uninstalling my drivers and letting windows reinstall them, changing my mac address, resetting the router, checked everything was plugged in, disable bonjour, tried releasing my ip and renewing it. I've tried so many things that have popped up on google that I have no idea what else to do. I don't want to reformat my computer if I can avoid it. If anyone has any idea I'd be so happy.I'm running Windows 7 x64 Home Premium. Other computers on the network are able to connect to the internet and I can access files from other computers on the network.

This seems to be an old problem going back to win7's initial release yet people are still having the problem now. Everybody told me to install win7, "it's awesome", "everything just works", etc...and here I can't even get online.Anyway, what I can tell you is that I'm on a wired connection. Everything else connected to the same router works fine. I've got another computer running Vista, works fine. My xbox & ps3 both work fine. This computer that's having the problem was working fine when I was running XP and Vista on it. So it's clearly an issue with Windows 7.I've checked for the Bonjour service I saw mentioned in other threads, don't have it. The next thing I should probably try is assigning a static IP manually. I'm fuzzy on how to do that since I have no experience with win7.
Im having a big problem with connecting to the internet. It was working fine a couple of days ago but now i cant connect to the internet at all. I have a windows 7 compatible laptop and google chrome is the default internet Im using. I have checked the wireless network connection status which reads "IPv4 Connectivity No network access" "IPv6 Connectivity No network access" "Media state Enabled". The unidentified network is currently set at Public network and cant be switched to anything else. l have spent 4 hours trying to resolve the issue of reconnecting but have had no luck.

so I have recently made a new install of windows 7 and now I can't seem to acces the Internet. I am using PPoE connection for the Internet which requires username and pass from the ISP, and yes I'ved checked if they're well written thousands of times before posting this but it still seems it doesn't work. The error I receive is: Quote: Error 691: The Remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remote access server. As I said before, I checked thousands of times if the data for the connection is valid and also called all the ISPs I have subscriptions from and said there's nothing wrong from their side. I used Windows 7 before for about two years and never had this issue. Also if I try to disable and enable the network again it says that it is unidentified, and under the title it says that there is no internet acces, but in fact there is. Anyone knows how to solve this issue? Been trying for two days almost now, and I'm out of ideeas. And another thing is if you're asking if I have anti virus software, no I don't as the Windows OS is freshly installed, I also did an online virus check but it seems there isn't any.
Working with a Windows 7 Pro 64 bit OS. I set it up in my home and applied all the updates. Bought it to the persons house and hooked it up there and all seemed fine except after some time the computer could not access the internet anymore. The icon in the task bar stated "Unidentified Network, No Internet Access". I went back and went into Network Sharing and removed all the unidentified networks which there were 2 and connected once again telling Windows 7 that this was a Home Network. It all worked fine, logged off, shut down and everything came back fine. I thought all was good until about 4 hours later I get a phone call saying they have no internet access again and that the taskbar icon again states Unidentified Network No Internet Access. What can I do to resolve this?
Now i upgrade Vista Home Basic to Window7 Ultimate during setup, i selected Home network and connect the wireless network but I can't access internet .What should I do ? Should I change to public network?
I have a new Packard Bell running Windows 7 Home Premium. The tower has been replaced once as although I could initially connect wirelessly to the internet, it became more and more problematic. When the shop checked it they said it was dropping the connection and therefore swapped the tower (charging me for backing up my info to my hard drive) At the time I asked if could be a Windows 7 issue and I was told no.
The new tower connected to the internet for about 2 minutes before dropping the connection and since then I have had the little yellow warning triangle and "unidentified Network - No internet access" message although occasionally it does identify the network but still had no internet access.
Even when showing the unidentified network message, it still shows that the Wireless Network Connection 2 is connected to the home network.
I don't know what information you need, or how to get it but am willing to try ANYTHING you can suggest!
The other computers are all happily connected - I am using my netbook to try to find the answer to the issue.
I have not loaded any of my own info onto the new system as thought it best to sort the issue first. If I can't use the computer for the internet it is pointless me having it and I will return it to the shop!
I have a Windows 7 32bit desktop and Amilo Li3710 Laptop with also Windows 7 32bit.
Both have WLAN.
motherboard of desktop pc is P5k deluxe Wi-Fi edition.
I made on desktop pc an ad hoc connection with protection and security key.
Turned on wlan on laptop and it was detected. But as i try to connect, at the end i get unidentified network and can't connect to Internet.
But my first try was a success and i had Internet and a working home group.
Now i don't know how sometimes i get home group (on my laptop i can share music, videos etc thats on my desktop pc) but i still don't have Internet. Or in the worst chase both are gone.
Now i noticed when i go to Network and Sharing Center and then enter "Change advanced sharing settings" i see that a Public is the (current profile). How do i change that to be the Home?
I've read multiple posts about this problem but no concrete solutions. My problem is a bit different than the usual usecase.
Win 7 64 bit
Asus p5k se (integrated NIC)
Everything was working fine (a couple of months) until today. The only thing I did was trying to install some extra memory into my machine. That failed (but is a subject for another post). Problem started happening after that, but I find it hard to believe that it the two things have a direct connection.
In my case, the NIC manages to get an ip from the router (this is a direct cable connection, not wireless) and the gateway address is correct. However I still get the Unidentified Network - No Internet Access error. I'll clarify that the IP and gateway info appears on the Details screen of the network adapter. The main status screen shows (among other things):
IP4 connectivity : No Internet Access
I cannot ping my router. It's as if the negotiation phase between the computer and the router goes fine and then nothing. Looking at the DHCP table in my router I can see that my machine appearing there with a 192.168.1.2 IP.
I tried all the usual solutions:
Uninstall driver and reinstall
no DHCP
turn off computer
power off and take out cable
disable and enable adapter
I also saw that some software named bonjoure is blamed for a similar problem but I don't have that installed.
I have installed Win 7 - Build 7100. It worked for 2 hours and since then all I get is the network icon in the bottom right with the yellow triangle. It states unidentified network - no internet access. It is a NVIDIA Network controller on a ASUS Striker II Extreme board.
My issue i'm having at the moment is that i can't connect to the internet nor can i connected to my home 's intranet LAN network.I turned on my computer on Monday to find that i got the Black Screen Of Death (Black screen with only the cursor after logging in to account)I booted into safe mode. Run several virus scans with multiple programs (Avast, Spybot S&D and Malware Bytes) as i hear the Black SOD is caused by malware. I found no threats. I couldn't use AVG or Kaspersky as they need an internet connection to update to most recent version, not helpful as i need an uptodate database!I also tried booting into safe mode with networking. This did not work. So i felt that there was a networking issue. I then booted into safe mode and disabled ALL network adapters including Hamachi and nvidia nforce networking controller. After doing so i booted normally and i got hold of my computer again! got past log in screen. the lot. I Have also noticed that my computer is slower than it was the day before. And it hangs for several minutes on the 'shutting down' screen.I have re-enabled networking controllers and reinstalled drivers for the nVidia nforce network controller. (i have also noticed a lacking of networks adapters in the device manager compared to what was present before disabling all network adapters/ controllers.)This did not work.
I tried pinging my router. And other computers, this didn't work.I also tried 'ipconfig /renew /release' command prompts and windows timed out connecting to some adapters.While typing command 'Ipconfig /all' i noticed that there was a lot of information which i feel that shouldn't be there!! (I'm at school at the moment, i will post information found in CMD prompt I tried 'CHKDSK /C /R' I recieved no errors I manually inputted the i.p. DNS & suffix mask address, nothing is working!
I've tried every online post about this issue that I can find and it's still not resolved.
I just installed Windows 7 on my PC. I did a clean install and my old system was Windows XP. I haven't installed anything on Windows 7 yet except for the below mentioned. Also, my internet works fine when XP is installed on it. Here is the list of things I've tried to be able to get online:
I've deleted the network adapter and let windows reinstall it.
I've updated the network card adapter to the lastest version. (it's a
marvell yukon 88E8001/8003/8010)
I've updated my motherboard's bios to the newest version.
I've updated my motherboard nforce chipset with the latest drivers.
After noticing that my computer is assigning an ip address of 169.254.157.90, I set a static ip to 197.168.1.9, set up the DNS servers, etc. that still did not work.
I've tried disabling the IPv6.
I've disabled the IP helper in services,msc
I checked for the service that adobe and itunes installs (which aren't installed), and it wasn't there.
I've manually set my network address.
I've updated my router's bios to the newest version.
I've tried connecting to the internet directly through the modem, without the router.
I've disabled the Windows Firewall.
I've edit my registry to change my DHCP Broadcast Flag.
I tried connecting the cable modem via usb but there doesn't appear to be a driver supported by windows 7 for my Ambit U10C018 through usb.
I've tried ipconfig /release and then /renew. I've also tried the /flushdns
I've tried disabling and reenabling the network adapter.
I've tried pinging the router and other computers as well as google, usually nothing gets out, but a few times it just times out.
I've watched my attached devices in my routers page on another computer and I do see the windows 7 computer try to connect but drop out.
And I've tried many combinations of the above mentioned.
Any other ideas would be appreciated, I may just try to purchase a new nic card and see if that helps.
And I should mention, I was able at one point to connect to google, but it disconnected me again before it finished loading the whole page and I haven't been able to get to that point again. Also, it does show that I connect to an Unidentified Network if I let the computer sit long enough and sometimes it will say it is connected to the internet, but I can't actually load any internet pages.
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.
I just got an Acer Predator. I transferred settings from XP using Windows Easy Transfer. The Internet connection was working perfectly. I installed Comodo Firewall, Avira AntiVir and ThreatFire. Then it could not connect. I plug the Ethernet cable into the XP computer and it connects no problem.I tried a system restore and it didn't fix it. I am running a thorough AviraAntiVir scan now on the Windows 7 system. I don't want to assume it is a virus, but the system was unprotected until I got the three security applications installed. I did also see some Comodo warnings and I approved going ahead because the security apps were installing at the time.
I'm not exactly the most tech-savvy individual, so I will try to convey the problem I'm having here. I'm at my girlfriend's house, and have two laptops with me. One is a Sony VAIO (which I am currently using), the other is an Alienware m14x (sitting right next to me). I use the Alienware to play Diablo 3, and have had no issues connecting to any wireless access points prior to this.My sony connects to her home network just fine (linksys), but the alienware will not. I enter in the network password, and when I try to connect, it gives me the yellow exclamation mark over the white connection bars. When I click on it, it says "connected" in bold letters next to the network name. However, above, it says "Unidentified network," and underneath, "No Internet access."I have tried disabling firewalls and anti-virus software, I have reset the router, the computer, the wireless adapter, all to no avail. I'm not sure what to do. I'm pretty sure it's not the router's issue since all other wireless devices in the house connect to it just fine.
