Acquiring network address...

Hi there. Today I woke up, turned on my laptop, tried to connect... Doesn't

It says acquiring network address then limited or no connection. I called my provider's technical support, just asked me to change the encryption to WPA, so it changed from limited or no connectivity to no connection at all Just that acquiring thing, and nothing happens.

I went to ipconfig. Boom! It's 0.0.0.0.. Renewed it, didn't work yet.

Refreshed that thing in services called Wireless zero configuration, didn't work too.

I even went to my router's administrating page, turned of security, connected, nothing too.

Although it works when I connect it with a cable.. But for wireless, no
