Hi, I recently got the roku 3 and it was working great. One day it completely froze, I’ve restarted it, unplugged it, changed the hdmi plug, and it always takes me to the wifi log in, but it takes hours to update and never finishes. It backs out and starts back at the language slide. Not sure that to do at this point.
Probably a poor net connection.
How's the line of sight and distance from your Router?
Roku 3 is a bit dated and contrary to pop opinion wifi devices
do get old and wear out. Particularly where wireless in concerned.
You could upgrade your Router as well probably.
And remember Ethernet is Far and Away less problematic
if you can.
