Ok so have a Dell Inspiron laptop that is running on Windows XP and I am unable to connect to the internet. This happened a little over a week ago suddenly and everything that I have tried has been unsuccessful. I connect to the internet through an ethernet cable that plugs directly from the wall to my computer, however I cannot get internet because my computer is telling me that a "Network Cable is Unplugged" when it clearly is still plugged in. I have tried using different cables and in different rooms of my apartment, and yet I still have the same problem. My other roommates are not having any issues so this lead me to believe there is probably a problem with my computer. My computer skills are on a basic general knowledge basis so I have no idea how to begin to attack this problem. Strangely enough, in my attempts to get on the internet, I turned on my wireless connection which displays a full connection in the icon at the bottom of my screen at good or excellent quality, yet when I open firefox or explorer (the browsers I use) I still have no internet. I am not sure if this is an indicator of the same problem I am having or just a separate issues, but I am in desperate need of help. So please if you have any suggestions I would greatly appreciate them.

here are some things to try :
can another computer connect to the same cable?
try another cable (cat 5 )
open the network connections icon by right clicking in it go to properties.
if the local area connection icon indicates not connected right click on it to enable it

[gd6627]

also make sure your firewall is not blocking your access go in control panel and open the firewall icon.

Welcome to TSG:
Look at network adapters in device manager>
Let’s take a look at the status of the network adapters

Device manager:

Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.
1. Under Network adapters, please tell me all the devices listed.
2. Are there any devices under Network adapters that have a red x displayed?
3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?
4. Adapter status should be “working properly and enabled”

Then we can take a look at some other areas.

If neither wired nor wireless connections are working, it could be a firewall issue. Try disabling your firewall to see if you are able to connect. Also, be sure you have connected to the wireless connection. Posted via Mobile Device

Thank you for your response, I have taken the steps you suggested and hope the information will help you to further understand the problem.

1. Under Network Adapters there are two devices listed
- Broadcom 440x 10/100 Integrated Controller
- Intel(R) PRO/Wireless 2200BG Network Connection
2. None of them have a red x displayed
3. No devices in the device manager display contain a yellow ? or !
4. Adapter status says that it is enabled and working properly

Again thank you for your time, I hope this helps.
- also, I do not believe it is a firewall issue as others are suggesting since that is one of the first things I tried and is always turned off on my computer.

[pedroguy]

OK:Sorry to ask you to do this,but we really need to see what the pc sees as it's networking environment.So:
From a Johnwill post on the Networking Forum

Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type the following commands one at a time, followed by the Enter key:

IPCONFIG /ALL

PING <computer_IP_address> For addresses,follow instructions below….

PING <default_gateway_address>

PING <dns_servers>

PING 206.190.60.37

PING www.yahoo.com
Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. IPV4 for Vista

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

The ipconfig is showing a working connection for wireless.

Wireless works, but not ethernet... Is a green light coming on when an ethernet cable is plugged in?
Posted via Mobile Device

[Shmandy19]

Where the ethernet chord plugs in there is one small green light on the upper left corner (looking at it from the back), however there seems to be an identical light on the other side that does not light up. As for the wireless, like I said all indicators point to a clear connection yet somehow every time I try and use the internet it gives me the address not found and that firefox can't find the server errors, which I attributed to just not having a connection, however I could be mistaken. These are just the same error messages I see when I have no connection

Let's do 2 things:

Network check list .

Network check list courtesy of Johnwill and Terrynet of the Networking Forum

Here's a networking debug checklist.

Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.


A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.


For Vista,type in CMD in the Search box after Start.

Check your Services are Started on all PCs:
• Computer Browser
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic.

.

While the default NetBIOS setting is correct for normal network configurations, it's possible for it to be altered, and it costs nothing to make sure it's correct. NETBIOS over TCP/IP must be enabled for normal network browsing.

Would not hurt to check your network connections for the following.

To enable netbios over tcpip


Select Start > Settings > Network Connections.
• Double-click the Connection icon of the connection you wish to modify to open the Local Area Connection Status window.
• Click the Properties button to open the Local Area Connection Properties window.
• Click to highlight Internet Protocol (TCP/IP).
• Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
• TCP/IP Properties window, IP Address tab
• Select Obtain an IP address automatically.
• Select Obtain DNS server address automatically.
• Click OK to return to the Local Area Connection Properties window.
• Click OK to return to the Network Connections window.
_
Enable NETBIOS over TCP/IP for 2K/XP
1. Right click the network properties for the connection in question.
2. Select Properties
3. Right click your Internet Connection (ex. Local Area Connection)
4. Select Properties
5. Make sure Client for Microsoft Networks, and File and Print Sharing for Microsoft Networks are SELECTED.
o Highlight Internet Protocol (TCP/IP)
o Click Properties
o Click Advanced
o Select the WINS Tab Above
o Make sure Enable NetBIOS over TCP/IP is SELECTED
6. Click OK and Close Network Connections Window.

OK;Here is the question I should have asked.
You have an ethernet cable from the wall plugged into your pc,but no connectivity.
As noted,you have a "good" wireless connection from somewhere.

Whose network are you connected to ?
Start/My network places/view network connections/ left click on the wireless connection icon(lan connection will probably have a red X through it)/view wireless networks.
What is the name of the connected wireless network ?
And that may be the reason your network pings are not completing.The router/firewall,wherever it happens to be,will not let you traffic to the internet.

[Shmandy19]

The wireless network I am connected to is linksys2 and it says it is an unsecured wireless network. Also, you mentioned that my ethernet cable being plugged in to my computer from the wall, however to clarify it is not a "limited or no connectivity" error but a "network cable unplugged". I was not sure if I made that clear earlier. I also tried to enable NETBIOS over TCP/IP for both connections with no luck. Again thank you for the continued help.

in Firefox, try connecting to your router's IP address over the wireless connection. If you can, then its the router, if not, then your wireless card is getting a false connection
