Q: If I network my LAN connection time is displayed with a red X and an error message that? A network cable is unplugged? (Not true in my opinion). I see that my LAN connection is very briefly once every 5 seconds (flashing computer gets an IP address), but the red X right back. For some reason my computer / network simply refuses to accept the IP address sent.
For your information:
My computer is directly connected to a broadband modem with the correct type cable.
The connection worked fine few days ago, but not anymore.
Have tried to repair the system without success.
Checked the status of the network cards in device manager. No question / exclamation marks.
Have removed from the network and the (latest) drivers and obviously reinstalled too.
No Internet firewalls or other potential obstacle is installed.
No new hardware or software recently added.
DHCP is enabled on the computer and must be so according to the ISP. TCP / IP settings, new seat correct.
Tried cable.
Tried network to another network to another network in another pci cable.
Tried card.
Tried slot.
The? Sync, dsl. @? LED lights on the modem, which indicates that the modem works fine.
ISP says no problems with the network.
The only thing I did (and still is reluctant to try) is to reinstall the OS.
Any tips on what I must try (before reinstalling everything and I can accept that? not find the problem)?

3): make sure you are using a Straight Thru Cat 5 cable and not a Crossover Cable Actually, sometimes modems require a Crossover Cable rather than a Straight Cable. If you switched out the cable for any reason try going back to the one that came with the modem. If that's not possible try with both a Crossover cable and a Straight cable and see what happens.
Re:Try this: … 1): Do a hard reset of the Broadband Modem .. see your instructions that come with it
2): if this is windows XP, get a program called Winsockfix from here: http://www.majorgeeks.com/download4372.html
3): make sure you are using a Straight Thru Cat 5 cable and not a Crossover Cable
Also make sure your broadband modem is set to automatically assign an IP address … if it does not
have this feature, then you will need to code in the Address in the Lan Connection Settings of the PC
Winsock should fix it
Re:If you cant try another computer on it, and dont want to reinstall O/S, then download knoppix, and see if it works.
Re:Under such a situation it is hard to know whether it is the Network Settings of your computer, the Modem, or your Internet Service.
You can go over your Network Configuration as described at the end.
However, if every thing turns OK you are back to square. One.
My personal solution to such a situation is to get a Cable/DSL Router. Beside the fact that it provides more secure and stable Internet connection (even for one computer) it makes it much easier to determine where in general troubles are (Routers can be found on sale for less then $25).
If you put a Router and you can Not connect to the Router from your computer then the trouble is with the computer. If you can connect to the Router and configure and there is No Internet then you know that it is time to call your ISP.

In General, you can debug the Network Settings of a computer by following these steps.
Step One. Check the Network parameters in the Computer's Device Manager. Make sure that the Network Card drivers are installed correctly; i.e. there is No IRQ conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost
Step Two. Verify Basic network setting in the OS: http://www.ezlan.net/Installing#verify If the above two Steps indicates that every thing looks good but functionally it does not work.
Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet
If need to Reinstall the Network Settings; Log to this page, it have a lot of links to instructions for Windows Network Installation – http://www.ezlan.net/Installing.html
