Laptop unable to connect to wireless network

[TheTake]

Well I was uploading some videos on Youtube on my laptop when the wireless connection just went off on its own. It could still detect my home wireless network but when I try to connect to it from the list of available networks it just stops halfway while trying to connect and refreshes the list again. When I tried right-clicking and the connection icon on the taskbar and choose repair, I always end up with "Windows could not finish repairing the problem because the following could not be completed: Connecting to the wireless network"

I don't think it has anything to do with the settings in the laptop because I get the same thing when I restored my C-drive to how it was 3 months ago using a back-up.

The house computer that uses the local area connection can still connect to the internet but I'm not sure whether any settings were changed here that would affect my laptop. I can't really restore the stuff here too to before my problem coz there's s lot of my dad's stuff are in here.

So is my problem because of something to do with the settings or did something in my laptop got spoilt @[email protected]?

I assume you've already tried rebooting the laptop. Next step would be to shut down all computers; unplug the router; plug in the router; boot computers. If still a problem please show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.
