Maybe you are having trouble with your CapLock key and entering the password in upper case
Else I might try:
1. Using an ethernet cable connection to check the internet works that way.
2. Deleting the entry for the network in System Preferences>Network>Advanced and starting again. Check you are entering the correct security type required by the ISP.
3. Wiifi diagnostics are available by holding the Opt key and clicking on the wifi icon in the toolbar. Then go to the Utility menu and select the Scan tab. If many of your neighbours use the same channel, you can go to your router and change your's to a different one etc.

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following may help although, unfortunately, not always. - in no particular order:
- Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
- Change the wifi channel on the router
- Create a new Network Location: http://support.apple.com/kb/HT5289
- Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

Nope, definitely did not have caplocks on. Tried all 3 and nothing works. Its always saying "network cannot be found" or "connection timed out". Weirdest thing is that, all the other laptops and even my iphone works.

Then you tried with an ethernet cable? If it cannot find the network this way, it is nothing to do with wifi. In System Preferences>Network, go to the Ethernet settings and check you are using DHCP and set the advanced options as per your other computers.

I couldn't get mine connected either, and when I was on this site trying to see if anything would work, nothing would work, so I clicked on System Preferences>Network>Assist me...>Diagnostics...
and then just followed all the steps, and now my Wi-Fi works! I hope this helps you if you haven't figured it out already, or helps someone in the future looking for an answer!
