Modem Does Not Recognize PC
When I try to connect to the internet, the modem does not recognize the connection. I have tested my ethernet cord with my laptop and it is a good cord. The local area connection flashes between a network cable is unplugged and local area connection is now connected. I have read some threads re this problem and have run cmd and config /all This is what is says:

Window IP Configuration
Host Name: DJBWR441
Primary Dns Suffix:
Mode Type: Hybrid
IP Routing Enabled: No
WINS Proxy Enabled: No
DNS Suffix Search List: cable.rcn.com
Ethernet adapter Local Area Connection
Medai State: media disconnected
Description: Broadcom 440x 10/100 Integrated Controller
Physical Address: 00-0D-56-5D-0F-83
Not sure if I need a new ethernet card or if there is a problem with settings?
The operating system is Windows xp.
Thanks.

do you have another PC at all
can we see a device manager screen shot

------------------------------------------------------------------------
Device Manager
Post back the results in device manager
You will now need to take a screen shot and copy that back to the working PC.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the screen shot and attach the screen shot in a reply on the forum here.

how to access device manager for different windows versions
http://www.computerhope.com/issues/ch000833.htm

Hold the Windows key and press Pause key, should open to allow device manager to be seen

on a laptop you may need to use Hold the Windows key and press FN key + the pause key

if this does not work then -

post a screen shot of the device manager - network adapters

To post a screen shot of the active window.
1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.

I opened the device manager, but it just lists the devices. Should I open the network adaptors or the modems tab. Not sure what you want me to copy and paste? Thanks.

Hopefully, that is what you wanted. Sorry if that is not what you wanted. If I click on the device there are several tabs. Is there something on the tabs that you are looking for. Thanks.

try this
------------------------------------------------------------------------
Safemode with networking
with a cable connected from PC to router
check the cable - see if there is a light on the router associated with the cable port used , also check if you have a green/yellow light on the PC LAN port
- try safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works

No, this did not work. It came up with the message IE cannot display webpage. The light on the router goes on and off. There is a yellow light at the LAN port. Do you think the network card is bad or is there something messed up in the settings. We were using DSL but now are connecting via cable. Thanks.

I have tested both the modem and the router with my laptop and they both get a connection with my laptop. When I look at the properties of the network adaptor (Broadcom) it says the device is working property. But is keeps connecting and disconnecting. The yellow at the port is always on but the light on the router blinks on and off. However, when I connect my laptop to the router, the light stays on? So, I don't think it is in the modem or router, but can't figure out what it is in the PC.

Thanks, that didn't seem to work. When I go into the control suite for the controller, the link status swiches from link status OK to link status down. All the other disgnostic tests pass. When I ping the IP address all is okay. Could there be a loose connection?

Thank you for all your help. I need to go out for a while, but will get back to this later. I can answer some of your questions--the commands did work; I rebooted and am still having intermittent connections. When I went into the modem suite, there was an IP address showing (it was previously blank) so I pinged that address. I'm sorry, I am not at the computer right now, because I need to recharge my laptop battery. Once it is recharged, I will rerun the original command and see if I get the same results (i.e. media disconnected). Originally, I had no connectivity, now I have intermittent connectivity.

Thanks again for all your help. I will check the thread when I return.

I have the router connected to the modem as well as the PC connected to the router. I also have a connection from the PC to the printer.
