jjb2014,
Tried looking in the Dell B1160w mono laser printer manual and could not find out anything about the wireless adapter installed. The onlt thing in the User manual is in the glossary on page 151 saying...
802.11b/g/n can share same hardware and use the 2.4 GHz band. 802.11b
supports bandwidth up to 11 Mbps, 802.11n supports bandwidth up to 150
Mbps. 802.11b/g/n devices may occasionally suffer interference from
microwave ovens, cordless telephones, and Bluetooth devices.
I'm not sure how old this model of printer is. In most cases, the older printers have a wireless adapter that works on 2.4GHz. I'm not sure how many printers are out there that use 5.0GHz. Some of the wireless adapters in the printers will recognize No Security, WEP and WPA-PSK(TKIP) Security(Personal)
