First I had this problem on my old Dell Pentium II computer. It would keep saying ''network connection unplugged''.At first I could plug and unplug and get it back. Eventually nothing. I went through tech support who said my modem was the problem. I got a new modem, installed the driver, still did the same thing. Then I went and bought a new laptop, cuz I need computer for school. I got the router going with it and had no problems. Thinking it couldn't hurt, I plugged my Dell into the router, and VOILA it worked. Well now I cannot connect again with the router or directly (Hughes net)with the Dell. I can connect directly with the laptop. Since I was having problems before the router, I wonder if it cannot be a virus that is now on my laptop. I am using AVG on my dell, and norton on my laptop. I ran zoombli advanced registry optimizer on the dell, and zoombli advanced system optimizer on the laptop. No viruses are read by the programs. The hughes net equipment is brand new and tests fine. My laptop is a brand new HP with windows vista. The dell uses xp. all cords are connected and not loose. the router is a linksys wrt54gs2v1 and I have cloned my mac address and everything.Like I said last night it was working fine. Now the laptop will not connect wirelessly and the dell will not connect to the internet longer than several seconds. Then I just get the page cannot be displayed message. I also should add that i recently installed a new memory card to the dell because after reinstalling windows several times due to viruses, I was out of memory and it wouldn't run at all. I have tried alot of troubleshooting and am ready to take it to the shop, but they will probably just tell me to reinstall windows. I need the computer access for a master's class so this is awful, and I have two little kids, so I need to be on wireless so I can go off into my room and work while my husband watches the kids. sorry this is so long.

    I reset my internet options on the dell and for some reason it is working now. The only problem is that I can only connect through the router still, which is fine as long as the router works. The reason I cloned the mac address was for the router to work I saw it recommended on the web site by cisco. It did indeed make the router work. Thanks to all

Seems that you are having a big trouble. :)
U cloned the MAC adresses ... I wonder what that means...Anyway......
Now both machines can't be connected to the internet...Did u check your network card of the XP machine? If there are any errors related to software drives, Get the computer management console by right clicking on My Computer icon and selecting manager. OR just do a search for Device Manager.
Then Get the device manager and click on it. Check whether there are any Yellow Exclamation Marks.
Go to the Event Viewer in the same console and under the System Category, Check for any Errors given with a red x.
Chek in task manager whether those processes are running. If so go to safemode (I'll tel you how) or just end those processes using taskmanager. Remove all those Startup entry ticks also.
Then you will ba asked to reboot, you can reboot after that.

Second step.
If possible, check your network card.
Third step. Of course Virus Scanning.
I don't recommend Either AVG or Norton.
This may probably b coz of a Virus Infection.
What you have to do is, get the Run box from the start menu and type in msconfig.
Then in the new window, go to Startup tab. Then read all the entries and search each exe to check whether its a virus. Or u can post it here. So we can check. Can u get task manager by pressing ctrl + alt + del together (exclude+) .

Step 4.
Reboot the system and press F8 before the boot screen appear. Then chose Safemode with Networking option. Then Log in after booting up and check whether it happenes again. You can do it for both machines.
If it doen't happen and if u cud connect to the net that means it has to be a virus.

In windows xp machine. Go to My computer DClick it. Go to tools->folder options->view
Set the option to View Hidden Files And Folders.
Under that there are two options (Very next two)
Remove those ticks.
Then do OK.
Then go to a root like C:
Now u will be able to see Hidden and system folders and files. Like System Volume Information and boot.ini, IO.sys, autoexec.bat etc. If you can't see them in both the Systems, that means the registry entries are modified by Viruses.

You can download online virus scanners from here. I will list the top 2 AV suite providers' Online Scanners.
Bitdefender.
Kaspersky.

Another thing. If you have shared any folders using the two systems, please remove them.

Next step is going to safemode and do a system restore

when u r entering you will be asked to. I don't think that its gonna make any difference to the XP machine coz its suffering from this trouble for too long.
If you can memorize the day that it went down at the very first time, you can try to restore the system at that point by selecting the date from the restore points, if thoses dates are available of course.

Try these steps and let up know.
The Q is long and the Answer is so long :D
Hope U can understand it.
Please, Kindly rate the answer if it is helpful to u.
Thanks
Best of Luck
:)

    MAC Address cloning - Reasons

    The device whose MAC address is monitored by an ISP can be either
    the cable modem, a broadband router, or the PC that hosts the Internet
    connection. The customer is free to build a network behind this
    equipment, but the ISP expects the MAC address to match the registered
    value at all times.

    Whenever a customer replaces that device, however, or changes
    the network adapter inside it, the MAC address of this new equipment
    will no longer match the one registered at the ISP. The ISP will often
    disable the customer's Internet connection for security (and billing)
    reasons.

    Some people contact their ISP to request they update the MAC address
    associated with their subscription. This process works but takes time,
    and Internet service will be unavailable while waiting for the provider
    to take action.
    A better way to quickly workaround this problem is to change the
    MAC address on the new device so that it matches the address of the
    original device. While an actual physical MAC address cannot be changed
    in hardware, the address can be emulated in software. This process is
    called cloning.

    Many broadband routers today support MAC address cloning as an
    advanced configuration option. The emulated MAC address appears to the
    service provider identical to the original hardware address. The
    specific procedure of cloning varies depending on the type of router;
    consult product documentation for details.

    That's the idea of cloning. And you have to reconfigure or reset internet options so that it recognizes internal settings.
    :)

Cloning your MAC address may be the source of your trouble. There is no reason to do that on your computers or your router.

The "network connection unplugged" message simply means your computer cannot "see" the network. It does not mean your cable is physically unplugged. If actually unplugging the cable and plugging it back in has ANY effect I would try a different cable. If you have the same thing with multiple cables I would replace the NIC.

Zoombli is worthless at best, harmful at worst. I would get rid of it at once. Do a google for it, you will see nothing beneficial except from their own home page. It would not surprise me one bit if your problem went away as soon as zoombli was gone.

Connecting 2nd computer to router via wireless

first, your router wont look for your laptop. your laptop has to find your router. make sure your wireless card is activated on your laptop. right click on the icon where it says network cable unplugged. it should then say "view available networks". click on that and look for your network. if you need further guidance, write me back and tell me what brand of laptop you have. also, for the second tower, if you are trying to go wireless with it, then you need a wireless adapter.
