I am having the same issue with the 50" onn ruku tv. I am connected to wifi, won't connect to the Internet. Have rebooted the tv, router, and Internet provider box. Nope. Nothing. Was working earlier today.
Same issue here. After updating the latest software, old tv would cycle over and over endlessly. Would never find networks. All other wireless items still work. TV under warranty, shop replaced all boards in tv. Said it was good to go. Came home same issue. ONN customer service gave me a refund. Ordered a new Onn TV tried to set it up today. All was going well until it downloaded the latest updates. Then I am back to no network access. Can't connect any longer. Need Help.
We recommend rebooting both your wireless router and your Roku device.
I'd also recommend trying to connect your device to an alternate network, such as a mobile hotspot, to see if you can activate and update your Roku TV. Then once your TV is setup, try switching back to your home wireless network.
I'm having the same problem with tmy 24" Onn. It won't even find my main network. It used to then one day it just stopped. It can find all of my neighbors, even my neighbor across the street. But not mine. I've restated the TV, I've restarted the modem/roter/gateway. I've moved the TV to within 3 feet of the router. No difference. Doesn't fin my 5G network anymore and on the secondary network it keeps going out and saying no internet. No other device in the house has the problem or has ever had this problem. Oh and the Onn customer service were AWFUL!!!! What a piece of junk I'm stuck with now.
Can you please provide us the following information: -Roku device model -serial number -device ID -software OS/version (these can all be found in Settings > System > About) -when did this issue start to occur
Once we have this information we will be able to pass it along to the appropriate team.
