The wireless printer's adapter is a wireless b/g adapter. It needs to use No Security, WEP or WPA-PSK(TKIP) Security Personal. The best connections for wireless devices are channels 1, 6 or 11, I use channel 11. If the printer is connected, the light on the printer, if there is one, will show if the printer is connected to your network.
You're not using Mac address filtering, are you? Do you have enought ip addresses to have devices connect to your network?
