RokuDanny departed from these parts quite a while ago.
Roku Streaming Stick models released since 2017 (model numbers 3800 and above) have an enhanced WiFi receiver that has been moved from within the stick itself and placed in a nodule in the unit's USB power cable. This cable is essential for the Streaming Stick's operation for connection to the internet through your local WiFi network and for communication with the Roku's remote. These Rokus cannot function if the Long Range Wireless Receiver is defective or if a plain USB power cord without the WiFi nodule is used.
• For Streaming Stick models 3800, 3810, and 3811:
These models use a WR001 cable with a USB-Mini connector on the end that plugs into the Roku Stick. This connector has a tendency to fail if the TV's physical configuration forces the cord to make a sharp bend right at the Roku, espeically if this must support the full weight of the cable. These models are discontinued and Roku no longer stocks replacements for the WR001 cable. Replacement cables for later Streaming Stick models are not compatible with the 3800, 3810 and 3811, even if a USB Mini-to-Micro connection adapter is used which would permit it to plug into the Stick. The only recourse for a defective WR001 is to replace the unit with a current Streaming Stick or other Roku model.
• For Streaming Stick models 4K and 4K+ (3820 & 3821):
These models use a WR002 cable with a USB-Micro connector on the end that plugs into the Roku Stick. Replacement cables are available from Roku for about $20:
