Connecting Brother MFC 465CN

I am wanting to connect my MacBook to a Brother MFC 465CN by wireless. The printer is connected to a Net Gear wireless router and my Net Gear is connected to my AT@T router. I have tried to download the printer driver via CD and from the brother website. However, when I try to print my Mac can't find the printer. The only way my Mac recognizes the printer is if I connect via USB. I have in the past connected another printer, and I had NO problems. I have read on-line issues with this problem, but I have not found solutions. Please Help.
