I have RokuExpess 4K+, my roku device keeps giving me error 003, which is network error.
When I try to reconnect, I don't see my wireless network listed. I have restarted modem, unplugged roku device and TV but nothing. I have texted w roku support and still no answer.
Help!
If you don't see your network in the list, there's probably one of two situations. The first is that the Roku has failed. Not likely, but certainly possible. But if it sees other networks, just not yours, then there's nothing wrong with the Roku. If this is the case, see if you can connect to a phone hotspot as a test to ensure the Roku is working correctly.
The second situation is your WiFi router is using a channel that your Roku doesn't support. Since all routers are set to auto select a channel by default, it's possible they selected one that isn't seen by a Roku device. On the 2.4 GHz radio, the channel must be between 1-11. If it's selected 12, 13 or 14, it is invisible to a Roku. On 5 GHz, there are channels called DFS, and early Roku devices cannot use them. The latest version of Roku (that uses the Realtek chipset, such as your Express 4K+) has begun to allow use of DFS channels. But there still might be some that can't see them. So on the 5 GHz radio, make sure it's using channel 48 or below, or 149 or above. Any channel between those two numbers might not be visible to a Roku.

If you appreciate my answer, maybe give me a Kudo.
