No internet windows 7 (Resolved)


Recommended Posts

I have been working on a Dell Inspiron 570 with Win 7 Home Premium 64 bit for the last two weeks. The only problem it has is that it will not connect to the internet. I have found lists of several fixes for this online and have tried all of the ones that I understood. None of them worked. The system shows that the ethernet cable is unplugged. Today, I put in a new pci ethernet card (Win7 64bit compatable) and installed the drivers. Like the onbord ethernet connection, it shows that the card is running properly in device manager. The computer shows that the ethernet cable is still unplugged. I know the cable is good and the router is working properly because I plugged in an XP computer to work on it a few days ago and the internet worked fine on it. This is the first time I have worked with Win7, so I am not very familiar with it.

The guy that owns the computer told me that the internet stopped working several months ago. He suspected that an improperly functioning Mcafee antivirus may have been the problem. That was the first thing i tried. When I attempted to start Mcafee, all I got was a blank white box that popped up. The same thing happened when I tried to uninstall it through add/remove programs. What I did was go through and delete all of the mcafee files everywhere I could find them and went through the registry and deleted every reference to Mcafee....That took some time. Removing all the Mcafee references didn't help.

Apparently, from all of the fixes I found (and tried) online, this is a fairly common problem with Win7.

 

Anybody have an idea how to fix it?

Tried the first video a week ago...back then I got 3 packets sent, 0 received'

This time I got "request could not find host"

 

tried the second video-it was hard to follow because I had to run magnification to 400% to see what he was doing-did everything except click on "refresh" because I could not find that option where the cursor was pointing. Still shows no internet connection.

look on the ethernet port where the cable is plugged in. there are two lights. are they lit up? if so, what are the colors and are either of them blinking?

 

if you have lights you have a good connection to the router and hardware can pretty much be ruled out. if no light then you likely have a hardware issue (the nic, cable, or router).

 

if you have lights boot into safe mode with networking. do you get internet there?

The lights are yellow. With the onboard ethernet there is a solid light and blinking when I try to get on the internet. The add on card shows yellow light but it does not blink.

 

No internet in safe mode.

 

The router (Windstream) works fine. Every other computer I hook up at that port gets internet.

With the computer connected to the router, Go to Start and type: cmd


At the top you'll see the command console icon.


Right click it and choose: "Run as Administrator"


At the prompt, type: ipconfig /all


Hit the enter key on the keyboard



Find the ethernet connection listed for your ethernet adapter and let us know what is listed for:


Physical Address


DHCP Enabled


IPv4 Address


Default Gateway

This computer is connecting properly to the internet with a Default Gateway of 192.168.254.254?

Is DHCP Enabled on that computer with the 192.168.254.2 address?

Yes, it is enabled. That computer (the one I am using to reply with) is XP pro. I have, in the past 2 weeks, switched cables between the 2 computers and the XP computer works on either ip address but the Win7 computer won't work on either......or the other two router ports that have XP Pro computers attached to them. Weird, isn't it?

Since the onboard Ethernet adapter has DHCP turned off, set the IP Address and the Default Gateway to static entries.

Try these:

IPv4 Address 192.168.254.8

Default Gateway 192.168.254.254

Here's how:

Click Start>Control Panel, under Network and Internet

Click on: View Network Status and Tasks

On the upper left, Click on: Change Adapter settings

Right click your Local Area Connection icon corresponding to your ethernet adapter and choose Properties

Now double click Internet Protocol Version4 (TCP/IPv4)

Put a dot in "Use the following Address"

Enter these values:

IP Address: 192.168.254.8

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.254.254

Put a dot next to: Use the following DNS server addresses:

Enter this value:

Preferred DNS server: 192.168.254.254

~ leave the alternate DNS address blank.

Okay your way out, click apply where needed and then reboot.

If it's still not working, power-cycle the router and modem and then try again.

Did both.........Ended up with a yellow triangle with an exclamation point between "computer" and "home network" that wasn't there before. Changed the last number on the ip to "6" like it usually is and got no change. Switched back to the 8 and again, no change.

 

I tried plugging it into the add on card (default ipv4 192.168.254.6) and the yellow triangle goes away, but the red X between home network and internet is still there.

The yellow triangle with exclamation point is typically an indicator of a driver error.

 

Uninstall and then reinstall the drivers for your "onboard" ethernet controller and make sure that it is enabled in the BIOS.

Once done, go back to the Static addresses and try it again.

 

If this doesn't work, re-enable DHCP and automate the DNS server to see if the router will do the configuration for you.

Setting the ip etc. back to automatic finally got rid of the triangle between computer and home network. Still have the red X between home network and internet.

 

I ran ipconfig afterward and it showed dhcp enabled and an ip address of 192.168.254.4

Is the correct Gateway showing: 192.168.254.254 ?

 

Something else to investigate, is whether IE has a proxy set.

Go to Start>Control Panel>Network and Internet>Internet Options

Click the Connections Tab, then click LAN Settings

Uncheck everything there.

Apply and OK your way out.

safe mode didn't work

 

 

Also, whwn I am in the command promp and click ipconfig /all, where it shows "media state" it is listed as disconnected. It has done this every time i have run the ipconfig for the past 2 weeks. The cable is always plugged in, but it always says media disconnected. Dosen't matter which ethernet plug in I use and changing the cable doesn't make a difference. I probably should have mentioned this earlier but I just watched a video that said "media disconnected" means a cable is unplugged.

Let's see if stopping and starting key network services has an influence.

 

Go to Start

Type: services.msc

Enter

Scroll down and find:

 

Network List Service (Manual)

Network Location Awareness (Automatic)

 

One at a time, double click the entry, then click Stop.

Then Re-Start the Service.

Stubborn buggar!

 

Do you have a Windows 7 disk?

If not, you can download and burn one from an Iso file here: http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/page-2#post-124821

 

Once you have a disk ready, run sfc /scannow from an elevated command prompt to repair or replace any corrupted files that may be causing this craziness.

 

Sure is a tough one to get going again. :mrsgreen:
