Exclamation Cannot connect to my wifi when other devices can
My laptop won't connect to my wifi. No idea why. I've restarted it, the router and the modem but it didnt help. Thing is it says that it can pick up signal on my wifi but it won't connect. The desktop computer works fine and mom's Nook connects to wifi and works fine, it's just my laptop not working. I've also tried connecting it directly to the modem and it still won't connect. Help?

TCP/IP stack repair options for use with Vista or Windows 7

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type the following commands, each followed by the Enter key:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

Reboot the machine.

When you tried with a connection to the modem did you remember to power cycle the modem when switching the device connected to it?

What firewall or security suite?

Did this laptop ever connect successfully to the router?

It is connected to the router, it identifies it too. I just tried the TCP/IP stack repair and restarted the computer but nothing changed

can we see an ipconfig /all
also can we see the results from the tcp/ip reset



------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste
------------------------------------------------------------------------
