Windows 7 ASUS laptop unable to connect to modem, but other devices can?

Recently my ASUS A54C laptop stopped connecting to my new modem (wirelessly), I can connect to the same modem with all my other devices including: iphone, ipad, smartphone and 2 other devices, except for my ASUS laptop. I can connect to other networks with my ASUS laptop just not my new modem. The modem got configured by the my ISP (adam internet) it is a NetComm wireless modem. I also can successfully connect to the modem via Ethernet cable. When i try to connect wirelessly i put the password in then it says 'unable to connect to (my network name)' in the troubleshooter it says no problems could be found.

I will list everything i've tried to do:

Turning my laptop off and on again,
Completely re-formatting my ASUS laptop,
Changing my mac address on my internal wireless adaptor (in case they blocked me or something),
Unplugging my modem overnight,
Changing to 'safe mode with networking',
Deleting Anti-Virus Software,
Hard resetting the modem

I know it isn't the wireless card in my laptop because i can connect to other networks.

Please help i have been like this for almost 3 weeks trying to figure this out for almost 2 hours everyday! 5 stars and 10 points for best answer please.
