my wifi works fine with all my other wifi devices (phone, tablet, labtops) EXCEPT for roku and this error "003 unable to update software problem " only showed up after two+ years of trouble-free wifi connection.
This morning at first roku had a different look, I didn't think much of it. then it seemed to want me to reativate roku (language, wifi connect, etc)
by the way, i had disconnected, reconnected roku at least 10 times today, my wifi connection is extremely strong, after 3+ hours I still get the same 003 error message.
Thank u so much. A hot spot was what i needed in deed. My bad. Turned out it was user error on my part, because I paused roku on my google wifi. Because of that roku , couldn’t get WiFi connection. Once i unpaused roku on google wifi, connection was reestablished.
