It started with my TCL Roku TV won’t connect to wireless network. Spent 2 hours with TCL tech still can’t solve problem. It worked when I used a Ethernet cable to connect internet.
Then the next day all of sudden my Roku Express showed no signal. Tried all solutions posted ~ turn on off, router, change HDMI port, changed TV, nothing works. Then my other Roku express+ also showing no signal. Both devices lights are on but blinking. Internet is fine since TCL Roku TV with wired Ethernet cable working.
So maybe the main problem is Roku device can’t connect wireless.
All three devices not working. Please help a loyal Roku customer.
