Solved! Dell wifi not connecting. HELP!!!

[Pollybee]

I have a Dell inspiron 5720 64 bit, running windows 8.

I connected to the internet fine yesterday, but today I can't connected. It shows me all the networks available, but when I try to connect it says "can't connect to this network"

I have tried rebooting both laptop and modem. But it's not working.

My phone and everyone else's laptop are connecting fine.
What do I do?? I need this laptop for university!

Try this....

1. Go to "Control Panel".

2. Next go to "Network and Internet" and then "Network and Sharing".

3. Now click on "Manage Wireless Networks".

4. On this screen, remove all wireless connections by "right clicking" on it and select "Remove network" from the drop down menu.

5. After doing this, close the open windows and reboot the computer.

6. Once the computer is fully reloaded, scan for the "Wi-Fi networks".

7. Click on the available network that you want to access and select "connect".

8. It takes a moment, but then you will be asked to give a password for your Wi-Fi connection. Type in the password and click the "connect" button.

It should now be connected.

NOTE: If this doesn't work, you may want to reset your modem/router, and then once it is fully loaded again, repeat the above steps.

If this doesn't work, test seeing if your laptop will connect via Ethernet. If so, then your WiFi card may be going. You can either look to replace it/have it replaced, or get an external (plugs in via USB) WiFi card.
