Hi chipsAUS,
Thanks for your message. But just so you know: if you want Samsung support, I support US products and customers. And from what I can tell, this model is for Australia. (Correct me if I'm wrong.) So while I can't help you directly, if you want Samsung help, here's the Samsung Australia portal for support on that product: http://www.samsung.com/au/support/model/UA55B7100WFXXY
Hope this helps you!
Regards,

I have a samsung series 7 LED Model Code UA55B7100WFXXY and have purchased a samsung dongle WIS12ABGNX. I can not change under Setting> Setup> Network Type to Wireless. It is greyed out and set to Cable. I have updated latest firmware by USB and confirm the USB port is working on the TV. I have connected the dongle to my computer which has recognised the dongle. But I can not activeate the wireless network type on my TV.
