Preparing for Internet connectivity 
If you want to watch streaming content and take advantage of the cool features of 
your TCL Roku TV, connect it to the Internet through a wireless modem/router or a 
wireless access point (not provided). The TV has a built-in wireless LAN adapter.  
Note: 
The TV supports only its internal wireless network adapter—it does not support 
the use of a USB network adapter.
 
 
Select 4K models have wired in addition to wireless network connectivity. To use the 
wired network connection, connect an RJ-45 Ethernet cable (not provided) from the 
jack on the back of your TV to your network router or switch. The wired connection 
supports both 10 Base-T and 100 Base-T Ethernet.
