Since yesterday my Laptop hasn't been able to connect to the internet, whether it be through Chrome, IE, Online Games or to update software. It says I am connected but can only get limited access to my router's WiFi. I have tried unplugging the router and modem however that didn't solve any issues. It definitely isn't the router as I can go online with my Xbox 360, smartphone and Nintendo 3DS. I also tried using my smartphone as a WiFi hotspot and connecting through that, but again could only get limited access. I am currently posting from the family desktop which is connected to our WiFi. I would very much appreciate any bit of help that can be offered. EDIT: I should also add that I am using Windows 7 Premium 64-Bit on my laptop.

Hi Harry. The first thing I would try is to open Device Manager, expand Network Adapters, right click on the Wireless adapter and select Uninstall. Reboot and Win 7 will rediscover the device and reload the drivers. If asked during the uninstall if you want the drives also removed, reply NO.

Hi Ztruker, I'm afraid that didn't solve the problem, I can still only get limited access to the WiFi.

Let's see what ipconfig shows:

Click on Start then Run and paste the following into the Run box, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close.

Did you recently do a Windows Update?

I'm not entirely sure if I did, but whenever I'm prompted to update, I do so.

Everything looks good there.

Try this from a Command Prompt.

ping www.mozilla.org
ping 63.245.209.11

This is what I get:

>ping www.mozilla.org

If pinging the IP address works then you have a DNS problem. If neither works then it's something else, possibly WinSock (Windows Socket Services). You could download and give this a try: WinSockXPFix

Hi, this is what I get from cmd: C:\Users\Harry\ping www.mozilla.org Ping request could not find host www.mozilla.org. Please check the name and try again. C:\Users\Harry\ping 63.245.209.11 Pinging 63.245.209.11 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 63.245.209.11: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss) Winsock did not seem to solve anything either. I noticed this on Chrome when I try to load a page: The server at www.google.com can't be found, because the DNS lookup failed. DNS is the web service that translates a website's name into its internet address. The error is most often caused by having no connection to the internet or a misconfigured network. It can also be cause by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.

Looks like a DNS problem, possibly an ISP problem. You can try using the OpenDNS servers. They are what I use.

The addresses are:

208.67.222.222
208.67.220.220



Hopefully the screen shots are sufficient to show you how to set them up. If not, let me know.
