LAN network unidentified. + No internet/ intranet!! HELP!

lilpopjim · Mar 28, 2012

Hi!

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. It's very frustrating.

Here is how the problem raised.

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'm really stumped with what to do! Can someone please help me!

Thanks in advanced. Lewis

Hello,

Well I had a similar issue previously. It was a bad cable. Do you have another cable to try out?

Also please list all of your hardware components.

szaboaz · Mar 28, 2012

Is a backup&clean install combo out of the options?

To be absolutely sure that it has nothing to do with hardware, I would boot an Ubuntu Live CD/USB, and check if it can connect.

PartialGenious · Mar 28, 2012

Well you have several possibilities here that could be the problem. First off, is there another computer connected to your router/network? What are you connected to a router, modem etc.. This is a wired connection I would assume ethernet not wireless? When you do a ipconfig/all do you get a valid ip address or something like: 169.xxx..xxx.xxx if you get a 169 ip address then whatever you are connecting to (IE router, cable modem, dsl) is not broadcasting DHCP correctly. If you are getting a valid IP address 192.168.xxx.xxx this is an inside IP address which is coming from probably your router. Anyways try to ping your gateway which should be under the same subnet (a whole other subject). Essentially try those things and tell me what you get when you run ipconfig/all. Himachi could be causing issues as well just for reference maybe uninstall that too.

Report back with more information and hopefully we can help you out.

lilpopjim · Mar 28, 2012

yeah should have one laying around somewhere. ill try that out now.

cpu: core 2 quad q9400 3.0ghz overclock
ram: 4gb ddr2
gpu: gtx 460 1gb
psu: 650w corsair tx series
mobo: P5NE - SLII

lilpopjim · Mar 28, 2012

szaboaz :

i was planning to clean install when the new ivy bridge cpu release. but for now i think its too much to sort out. i have AS EXAMS in a month, and ill keep your idea in mind

The following numberical/ alphabetical sequences doesn't seem right with me, am i correct?

And you are correct, i'm conecting via cable, and as you may ahve noticed, all of the adapters except the nVida nforce controller have 'DHCP Enabled' set to no.

I'll uninstall Hamachi now for you.

Also as a previous user has said, i tried 2 other cables. Nothing happened.

Thanks for the help!

PartialGenious · Mar 28, 2012

Yes, Himachi does lots of odd things compared to just troubleshooting a regular network. Not sure what you were using it for as it kind of creates a tunnel or VPN (virtual private network). Definitely turn it off or un-install it before we go troubleshooting any further. Then run an ipconfig/all and repost results. Also you never answered any other questions as is this the only PC having problems? Do you have a router or connected straight to cable/dsl modem etc... so we can determine if it is just your computer or possibly your ISP (internet service provider) or a router which is yours etc.

lilpopjim · Mar 28, 2012

Yeah sorry i was in a bot of a rush at the time when i first answered you. I use Hamachi to connect fo friends to play 'LAN' games etc for a bt of fun etc. And i've also uninstalled Hamachi. And yeah i have a router. It's an AOl router which was provided not that long ago. Never had problems since i got it. And i have another desktop wired and 2 laptops connected wirelessly. 3 smartphones and my tablet are also connected wirelessly. They all get perfect siganl and an internet connection.

Heres the updated config.

szaboaz · Mar 28, 2012

Can you copy another ipconfig /all output from another computer?

Do you have fixed IP set in IPv4 settings?? (I see the "Preferred" address is being set, but the gateway is empty.) What happens if you set it to automatic?

Jim_L9 · Mar 28, 2012

That address means you aren't getting an IP address from the router like you should. If you do an IPCONFIG /RENEW from a command prompt do you get a different IP address. Does the port on the router where you are plugging the cable from your PC show a link light?

And yes the green LED on the router is lit up

Jim_L9 · Mar 28, 2012

Did you try an IPCONFIG /RENEW from a command prompt? Does the jack where the network cable is plugged into the problem have a link light, and if so is it lit?

lilpopjim · Mar 28, 2012

szaboaz :

Hi, sorry what do you mean?

lilpopjim · Mar 28, 2012

@jim_L9

As said the LED is lit on the router, it's also orange/ yellow on seperate led's on the socket on the motherboard.

And yes i have tried that. It comes up with the following error.

C:\Users\lewis>ipconfig /renew

Windows IP Configuration

an error occured while renewing interface local area connection : unable to contact your DHCP servre. REquest has timed out.
An error has occurred while releasing interface loopback Pseudo-Inteface 1 : the system cannon find the file specified.

techguy911 · Mar 28, 2012

Sounds like you have a rootkit best way to clean these rootkits is to get an emergency boot cd AV like kaspersky or bitdefender boot off the cd and clean your machine make sure a lan cable is plugged in.
Another reason for black screen of death is you hard drive could have a bad sector or corrupted system file to fix this in windows 7 go to the repair option then select command prompt and make sure you are on c: drive and type chkdsk /r
If you can't get to repair option in windows 7 then the you a windows 7 repair cd it can be made on any system that has windows 7 installed.

lilpopjim · Mar 28, 2012

techguy911 :

ahh okay. you also just reminded me that my friend gave me a me a windows 7 cd today. ill try the repair functionn and chkdsk again. said i had no bad sectors but something could of changed. thanks for the suggestion. ill make a boot cd right away!

Edit: I also have a painfully slow download speed.. I live in the country side.

Chainzsaw · Mar 28, 2012

Just a thought here...but how many devices does your router support? You didn't list the exact version - just "AOl" router.

Have you tried taking 1 device off, and trying the computer again?

lilpopjim · Mar 28, 2012

Chainzsaw :

the router supports up to 32 Devices. as ive said ive never had problems with this router.

router model: EchoLife HG532

szaboaz · Mar 28, 2012

Check out your IPv4 IP address settings:
http://windows.microsoft.com/en-US/windows7/Change-TCP-IP-settings

Are they set to "Obtain an IP address automatically", and "Obtain DNS server address automatically"?

lilpopjim · Mar 28, 2012

szaboaz :

I set the ipv4 ip yesterday manually. nothing worked. I'm not too sure about the ipv6 address though. I never attempted that. But to answer your question, yes they are both on Automatic

extremepcs · Mar 28, 2012

Either malware/rootkit took out your TCP/IP stack, or there is a problem with DHCP on your router. If you open the properties of your network connection (Local Area Connection most likely) under "This connection uses the following item:" what is checked/unchecked? Try unchecking everything except Client for Microsoft Networks and TCP/IP v4 and click OK, then reboot or run ipconfig /renew from the command line. If that doesn't work, disable/uninstall any antivirus or firewall software that has a firewall. It's possible (but not likely) that it could be blocking DHCP requests.

szaboaz · Mar 28, 2012

I see. I was going to suggest that you set it manually to something like this:

IPv4 Address: 192.168.1.100
Subnet Mask : 255.255.255.0
Default Gateway: 192.168.1.1
DNS Servers: 192.168.1.1

But if you tried that already, then I think I'm out of ideas.

lilpopjim · Mar 28, 2012

@extremepcs

I tried what you said and rebooted and performed /renew nothing changed. I'm so confused!!! I'll unsiall all antivirus etc after i've mounted a emergancy boot cd as suggested by TechGuy (thanks)

@szaboaz

I did ry it, yes but i'm new to the whole intternet diagnostics and customising of setting's etc. But the addresses you suggested are different from mine, i some what guessed them by using cmd prompt as a guide. I'll use yours, then will try the boot cd as said. I will then post results.

Thanks for the help so far guys/ gals. Much appreciated!!!

techguy911 · Mar 29, 2012

try tdsskiller and see if you have a rootkit.
another program you could try is combofix but you must be careful that you don't have an av running.
