wireless printing problem

I recently purchased a Netgear Unite internet device from ATT. It works very good, and goes with us wherever we go. It eliminates the need for wifi supplied by an outside vendor. My problem is that my Dell All in One printer V525W (wireless) doesn't automatically connect. I can print by plugging in a USB cord. I called ATT and a tech guy told me this device will not allow wireless printing. I doubt that this is correct.

My Dell PC is on Windows 7.

It think if I can change the SSID, it will work. But I don't know how to do this. Any body have a fix for this?

Thanks!
