If you use 1.17.22 as firmware version for your CFULLHDMA(i) and you want to use a WLAN USB dongle to connect your CFULLHDMA(i) wireless to your network: only a Conceptronic C300RU can work

But if you use 1.17.43 (latest firmware release) more USB Dongles are supported. Also the new C150RU Conceptronic dongle is supported, but ….. you can also use other brands as well. As long as the dongle is based on the Ralink chipset for 802.11n it can work. No guarantees though ;-)
