Wireless Router refusing password

[powerhouse7]

I have just bought a macBook Pro running Mac OS X Snow Leopard (10.6.0) and have attempted to connect to the internet via the AirPort to connect to my Wireless Router. I am already using the router/modem to connect my two other windows computers to the internet but when I try to connect using my MacBook it won't accept my password. I have tried all passwords used previously, but to no avail.

My Wireless Modem Router is as follows:
Netgear RangeMax ADSL Modem Wireless Router DG83 4PN

Any help will be much appreciated

Try changing the password on the router to something new... Try again.

Are u using WEP, did you try adding a $ to the front of the password?

The problem turned out to be the router needed to have the MacBook added as a trusted computer in order to connect.
Thanks for your help
