wireless

The original T1 specs say it does have built in WiFi

'Wifi module pre-installed : 802.11 b/g/n Wi-Fi'

Can you not find the settings options for WiFi thru the menus?
 
are you able to access your router thru the web browser ?
That access will show you your WiFi access key/name.
You need that Key or Network name to enter it into the dreamlink WiFi menu options
