PC Unable To Identify Router / Network (wired) - DNS Server Address Ping Fails
Jul 9, 2012
Last Friday my main desktop crashed (lost power to the machine) and on restarting the PC was unable to "identify" the network. By identify, I mean, when using "Network and Sharing Centre" on the basic network information page, the PC shows "Identifying" under "active networks" - no matter how long I leave the PC.
PC details
Model: Packard Bell Power x-30
Processor i7 870 @2.93GHz
RAM: 8GB
O/S: Windows 7 Home Premium (64-bit)
The main desktop is connected to the modem router (via Ethernet). The modem router is showing no sign of any problems itself, all the dashboard lights look ok (i.e. power is on, port 1 shows the Ethernet connection in place, both wireless bands are lit, the DSL is lit and so is the internet). The household contains a number of laptops which continue to work ok wirelessly and/or wired through Ethernet. Even mobile phones are accessing the wi-fi ok.
The DNS Server address looks ok, as that is the address of the web page to the router. I cannot access that web page (address) via the main desktop, but I can from other devices ok. Having gone through Device Manager the Realtek PCIe GBE Family Controller is showing as "working properly". I have tried pinging the DNS Server address, and that fail. I have gone through a system restore to a previous point (before the day of the crash) but that seems to have made no difference either.
I have attempted to set the IP addresses (for TCP/IPv4) directly
IP address 192.168.0.3
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1
And therefore forced to set the DNS Server address too
Preferred DNS server: 192.68.0.1
But I don't know what to set for the alternate DNS Server, so left blank. This seems to step me forward, in that the device/network is now identified. However the internet access is still not work, as the "DNS Server is not responding".
Hey, I've recently reinstalled my Windows 7 Home Premium and I since my PC does not detect the router.I've tried using a SKY recovery disk, but that failed and nothing happened. Do I need to download a specific driver so the PC can detect the router?
My Windows 7 laptop works Fine at home on my broadband with a wired connection, When I take my laptop downtown and try to connect to a company network, via a wire, windows 7 fails to find the connection.
I have a wired linksys router that works fine. I'm not using DHCP on it, its setup at 192.168.1.1. My pc which only has a wired NIC, connects with no problems.I recently bought a tplink wireless router. I changed it so the ip is now 192.168.1.254 (it was 192.168.0.254 originally which meant I couldnt access settings to change from the default password, SSID).
I got the tplink wireless router, so I wouldnt have to be tethered with a wire on my laptop for internet. However, I've wasted time with tech support which I can barely hear or understand.I'd like to get this working, otherwise I'm sending everything back, wireless router and laptop.I can ping both the linksys and tplink from my laptop with no problems.I can get connected to the tplink wireless router without a problem but I cannot get to the internet.
Just today I decided to download the Windows 8 consumer preview and setup my PC to dual boot with it.I am running Windows 7 home premium 64bit and the 64 bit windows 8 on my other partition. After setting up a separate partition on my hard drive and loading windows8 to this partition, I was all up and running. I had no problems setting up or running windows 8, the problem came when I booted back to windows 7 for the first time. When I booted into windows 7, I was getting the "unable to identify network" error, and no network connectivity.
First thing I tried was simply disable/enabling my network adapter thinking it was just some hiccup. No luck there. Next I pulled the power from my router, and let it completely reboot. Still no luck. I then shut down my pc and booted back into windows 8 and sure enough I am able to get internet connectivity when I am running windows 8. This got me to thinking that when I loaded windows 8 there may be some new drivers installed for my network card that are somehow causing issues when I load into windows 7 again. Not sure how this is possible.
I was under the understanding that when I loaded Win8 to the separate partition that it would keep all it's drivers and settings there and not effect anything when I was loaded back on windows 7 (This logic could be completely wrong, I don't know). So I rebooted and loaded back into windows 7, went into device manager and uninstalled both network adapters and drivers, and rebooted into windows 7 again so it could re-discover and setup the network cards with default windows 7 drivers. This did not work either and I am still getting the same error.
My internet isn't working too well, it shows great signal strength and says its connected but won't let me access the internet. It works if I reset the router but I keep having to do this as it only works for a limited amount of time sometimes for 5 minutes sometimes for 5 seconds. I keep getting this message when I try to access the internet:Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address.
There's a program I use (Pocket Informant iPhone Outlook Sync) which requires that my PC and iPhone be on the same network in order to sync.
The problem is that it works only when using my home network. When I'm at home, from my PC I am able to successfully ping my iPhone, which is connected to my WiFi network. This works whether myh PC is also ethernet-connected or WiFi-connected.
When I travel, however, even though I successfully connect to the WiFi network on my iPhone and PC, I am unable to ping my iPhone.
I have tried disabling the Windows Firewall and I get the same result!
I can't believe that all these different WiFi networks I connect to (airport, hotel, work) that they all have a configuration issue, so I'm thinking that the reason for the discrepancy must be because of some setting/configuration on my PC/home network.
Is there anyhing else besides disabling the Windows Firewall that I can try?
For some reason my router and modem will not show correctly on my dell inspirion one desktop. Im running windows 7 and here are the net work connection deatils
Connection -specific DNS Belkin Description Realtek PCIe GBE Family Controller Physical Address 00-00-00-00-00-00 DCHP Enabled Yes Ipv4 Address 192.168.2.2 Ipv4 Subnet Mask 255.255.255.0 Lease obtained Wednesday, November 10, 2010 9:45 PM Lease Expires Sunday, December 18, 2146 4:17 AM IPv4 Default Gateway 192.168.2.1 Ipv4 DHCP Server 192.168.2.1 Ipv4 DNS Server 192.168.2.1 IPv4 WINS Server NetBIOS over Tcpip enabled Yes
The Connection was working about ten days ago and then suddenly stopped and read as an unidentified network no internet access. at one point is was not receiving packets but now it is but it still says no internet access on the IPv4 Connectivity. Media state is also enabled and the speed is 100.0 Mbps when i troubleshoot it says windows cant identify problem but in the details it says default gateway is available. when i use the cmd prompt ipconfig/all my local ethernet adapter has a physical address of all zeros.
My internet connection shows 'no internet access' even though my ISP shows the connection is coming into the house just fine. I usually use a router (NetGear-WNR3500U) but I right now I have the Ethernet connection plugged directly into my PC. I tried directly plugging into my laptop and the internet works just fine. So I know the problem resides in the PC.
Some troubleshooting things I have tried.
-Power cycled my modem, router and PC.
-Repinged my connection from my ISP(Comcast Xfinity)
-Used the reset option on the router and the modem
-I was walked through the internet options needed with the tech support from my ISP to make sure DHCP was enabled and every other setting was correct, and he cleared me that all settings were correct.
-Tried ipconfig commands to /renew and /release my IP When I tried ipconfig /renew I get the error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server'
-Restored my PC to a restore point where the Internet was working
All of these options did not work.
What I think the problem is and I am not sure how to fix it, when I run the ipconfig /all command my Auto configuration IPv4 Address shows 169.254.112.76 which I was told is a router IP address even though I am plugged directly from the modem to my PC with an Ethernet cord. So I think that's my problem? But I am not sure.
We have a Window 7 machine on WiFi that can ping google.com fine but won't load a website or IP address (router admin panel).We have tried accessing the internet and the router admin panel via a smart phone and it all works ok.So this point me to the computer being the problem.I have check the setting in Network and Sharing center for IPv4 and these are all set to obtain automatically.
Have read and tried everything here to get my Windows 7 PC to access my XP laptop using its name. Have 3 machines. 1 PC ( ip 192.168.0.102) and 2 XP Laptops (say LXP1 and LXP2), one is ...104 the other, the troublesome one, is ...101. If I ping the machine name: ping LXP2. I get the ping returning with the ip address of the PC (...102). If I try to access LXP2 from Windows 7 PC, in Network in explorer - I am asked for the Password for the share. If I use the ip address 192.168.0.101 in the address bar at the top of explorer ( //192.168.0.101), the shares open and I can access the machine correctly.
Why does ping on the Windows 7 PC return the address of the LXP2 laptop as 102 (the PC's address) but the LXP2 laptop IS correctly configured to have an address of 101 and it open on the PC with this address. This looks to me to be the reason that when trying to open the machine name (LXP2) on the PC in Network in explorer, it fails and askes for a password. The other laptop works perfectly every time. And the 2 laptops can 'see' the shares and access them on the PC. Both laptops can see each others shares and can be accessed. Its 'just' the Windows 7 PC to LXP2 access that appears faulty. I tried disabling 'Network Discovery' and that did briefly work. But this morning - its back to its old self again, will only work when using the ip address...
I've got a Window7 Pro SP1 64bit that I'm trying to wireless map to a Samba share on a Ubuntu Server. I've read numerous posts online and have done the following without any success yet:
Both enabled and disabled Network Discovery... doesn't appear to make a difference. Changed Local Group Policy, Network Security LAN Manager Authentication Level to Send LM and NTLM - use NTLMv2 if session security if negotiated... but it has changed itself to Send LM and NTLM responses whenever I have checked it. I've tried using both the \Server IPshare directory and \Server nameshare directory in the Computer>Right Click context menu... Map Network Drive dialog boxes. My most recent error message there is A device attached to the system is not functioning. I've also tried using Net Use on the Command Line both ways. I've gotten two different error messages... error 53, and error 64.
I have a Windows7 Home Premium SP1 64bit computer networked to the Samba share, and it works fine. These two computers are in the same WORKGROUP.
I reinstalled windows 7 home premium on my notebook, and downloaded the NIC & other necessary drivers from the manufacturer's website. I have no other software on the N/B. When I connect the LAN cable I can successfully ping my router, but not www.google.com. I can see the other PC's on the network. The icon on the bottom right shows a yellow triangle and I have no internet access. I have an automatic IP & DNS server set in the IPv4 & v6. I have a desktop PC running Windows 7 on the network that connects to the internet with the router.
I can't understand how a newly formatted PC struggles to connect to the internet (via LAN), when my username & password is already setup on my router.

I just upgraded my fileserver to 2008 R2 (clean install) and also upgraded my home PC to Windows 7 (also a clean install). Both are connected together using a linksys 8-port gigabit switch and each machine has 2 NICs which are bridged. The server has a static IP and the workstation currently has a static IP as well (although I've had it set for DHCP and the problem still occurs). Network Discovery is enabled on both and they are both in the same workgroup.
Now with that being said, here's the issue.....
Periodically, the workstation no longer can "see" the server if I try to browse the network. However I can still ping the server by IP as well as name, browse fileshares and even RDP into it. The only thing that is affected is if I'm using a program on my PC and need to access files that are on a network share, then the server isn't listed under network to allow me to browse to the share.
When this happens, I can usually reboot the server and then it will show up, but there seems to be no set pattern as to when it will disappear. If both machines are left on and not rebooted, the server sometimes will just show up under Network for awhile and then disappear again. One final note, on the server, the workstation does show up when browsing the network.
I have a problem with my wireless internet card (Qualcomm Atheros Ar9485). It has trouble connecting to websites. Speed and ping is fine, but it is the connecting that often fails. I have done tests on my other computer and on my iPad, and everything works fine. I know that there is something wrong with the wifi card, because when I plug in my ethernet cable, everything works fine. My wifi drivers are up to date. I can still browse the web wirelessly, but 30-60% of the time, the connecting fails. I have had this kind of issue before (All browser slow/not loading pages) and I got the problem solved by switching wifi channels.
I have installed windows XP mode for windows 7 and it works fine. I have even installed few apps that were not possible to be installed on win 7. I played with win 7 virtual PC and have few questions:
1. I see that system chosen 120 GB for this virtual Win XP, I was not asked about this and wonder if this could be changed. The originally C: system partition in win 7 is 300 GB. 2. When I use cmd command in run and type ipconfig, I see that correct IP address is displayed (192.168.1.65) since it works in private network and internet is working OK. But when I try to ping router (192.168.1.1) I get message that "request timed out" occurred. Of course, ping works in windows 7, and I have internet access in both win7 and virtual win xp.
Just did a clean windows 7 x64 installation on a build a box computer with a new hard drive. Install went fine. Plugged it in to my 3 month old Linksys Wireless G Broadband Router (WRT54GL) and it doesn't recognize that there is any connection at all. Windows says "No connections are available" and troubleshooting can't identify the problem. The light on the router and on the computer comes on. I am running a wired connected XP computer and 2 Win 7 x32 wireless connected computers just fine. Ran ipconfig /all and it came up as follows:
Host Name.................... : Bottomdweller-PC Primary DNS suffix.......... : Node Type ....................: Hybrid
[Code]....
All wires are connected. I've tried booting in Safe mode with networking. I've even connected the computer directly to the cablevision modem. I've installed a USB Linksys wireless adapter and although it installs fine, it doesn't see the router at all. I've also tried reinstalling the router directly on this computer but it doesn't see the router at all.
I've tried setting up a new connection or network, Connecting to a network and choosing a homegroup and sharing option but since you need a network to connect to first I couldn't do it.
I need to switch from a wired network to a wireless network. Santa is bringing a new laptop. I guess the best way is to change routers. Not sure what to go with.I currently have 2 desktops, PS3 and a TV on the wired network. Ive looked at and read the reviews on a Linksys-Newegg.com - LINKSYS E3000 Wireless Router simultaneous Dual Band Gigabit 802.11a/b/g/n 2.4GHz / 5GHz up to 300Mbps with USB Built-in UPnP AV Media Server and an Asus-Newegg.com - ASUS RT-N16 Wireless Router 802.11b/g/n up to 300Mbps DD-WRT Open Source support with USB Storage, Printer And Media Server.For the most part the reviews are good but there a bunch of bad ones. Just wondering if any one brand is considered more reliable than the others. I don't know anything about open source firmware. Its mentioned quite a bit in the reviews.
What are my options for connecting a laptop wirelessly to a workstation that is connected to a wired LAN and has no router?Essentially, I want to add wireless connectivity to the workstation so that the laptop can connect to the wired LAN via the workstation.
I have been trying to set up a router at my girlfriend's apartment. I first tried a Linksys router that I had brought from home. I hooked it up from the wall port, to the router, to my computer. I was able to access the normal Linksys wireless setup page at 192.168.0.1 and set up a network fine. I then unplugged my ethernet cable and attempted to connect to the network and was not able to. If I recall, it 'connected' but there was no internet connection.
I've recently have a Sony Vaio laptop that will not get an IP addess and cannot identify networks. Both wired and wireless stay at identifying network, no internet access. At this point i've uninstalled Bonjour, reset my winsock catalog, checked the LSP, checked proxy setting - none, tried static information with no luck, uninstalled devices and reinstalled, deleted device drivers and reinstalled with new drivers, ran tweaking to reregister files, remove policies set by infections and so forth. I've scanned the PC with Combofix, Emsisoft Emergency Kit, TDSSkiller, and Malwarebytes and have found nothing. I've also removed the drive and scanned it externally. I'm almost down to a backup and reload. I've also remove IPv4 and IPv6 and reinstalled.
My dads laptop worked fine with the WIFI for about 1,5 year, and now yesterday his computer won't identify our router. I have tried reinstalling the driver to his wireless hardware and that didnt work. I have tried with a static IP, but i wasn't sure if i did that correctly, so i can't safely say that what i did with the static IP would work either way.
i have desktop with internet connection via cable to ADSL2+ Router and 2 laptop with internet connection via wirless to Wireless Access Point which is connected to the ADSL2+ Router

Why does my HP LaserJet P2015dn not print? It says Printer Offline. I am using Windows 7 but this has happened before with other versions of Windows and I have had to have it fixed. There is another computer connected to the printer.
My computer has and onboard PCIe network card and another PCI network card. I have connected my cable modem to the PCI network card using ethernet cable and have the internet on my computer working fine. This computer then connects to the other computers in my network using a hub, but it keeps putting this connection as a public network and wont share the internet to the rest of my machines even though I have the computers on the same workgroup and sharing enabled. I am running Windows 7 Ultimate 64bit.
I have just set up a new Windows 7 computer and am trying to access the HD across a home wireless network from my XP laptop. XP can see the Windows 7 but it is asking for USER NAME and PASSWORD. I put in, what i think is, my user name on the Windows 7 in the dialog box and then put in the password that I use to log into the Windows 7 when I boot it up but it rejects these. I went to look on the Windows 7 for user name and password and can't seem to find it in PROPERTIES of COMUPTER.
