Limited or No Connectivity

Specs: Windows XP
I have a LAN network and I connect to a modem by a cable. My laptop always ran fine on the network, but my desktop never connected. Very recently, I had to do a system recovery on the laptop, and after I did, the desktop was able to connect, but the laptop would not.

Now when I try to get online with the laptop, it says "Limited or no connectivity." I have tried almost everything and am at my wit's end.

I did all the ipconfig options in the command prompt. I turned on and off the modem and the laptop. I checked the firewall. I even tried a static ip and got connected but could view no pages.

The ip kept being 169.*** that's why I tried a static ip.

After the system recovery, the laptop went back to only having windows xp sp 2 and I'm going to assume this is the reason why I suddenly can't connect.

I don't know what else to do. I've been at this for two days now. Any help would be greatly appreciated. Thank you.

Does your laptop connect via a wired connection or wireless?

If wired,
- ensure you have the wireless interface disabled.
- check in Device Manager and ensure the interface is showing no issues
- ensure you have the most recent and up-to-date drivers for the NIC

You should probably go to the Windows Update website and ensure your operating system has all the most recent updates and patches.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

"I have a LAN network and I connect to a modem by a cable"

Is there a router anywhere in your LAN ? If not then that is your problem. A modem by itself cannot share an internet connection

"Limited connectivity" happens when:

•Your computer detects that a network is present and operating. That means that it detects that the network cable is plugged in, or that it was able to connect to a wireless access point.

•Your computer's request for an IP address went unanswered.
Connectivity is "limited" because your computer will likely make up an IP address. If you check your IP on your machine and it starts with "169." that's a made-up IP address. Only your computer knows about it, which means that no other computer knows how to contact yours. In addition, your computer doesn't know how to find or send packets to anyone else.
I would try to do the follow .

Renew the ip Address.

Know the range of your valid ip. See if you configure two PC with static Ip Address.

Check if you local ISP has provide one valid IP or it is on DHCP

Try setting a password for accessing the network.

This is not a big problem. Just let me know a few things that I asked.
