My roku express does not connect to Wifi, wifi connection says excellent. Tried to reset roku even factory rest it and it still does not connect. Tried to reset my wifi but Spectrum said there is no problem on their part and to contact roku. My roku tv connects to my wifi and works just fine. I’ve been trying for days to connect my roku express to wifi and it just will not connect.
There are some cable modems that have an "issue" with Roku devices. On the 2.4 GHz radio in the modem, there is a Mode setting. Many cable companies are setting the modem to only use Mode G/N. While in theory that should be just fine, for some unknown reason (but it's something in the modem firmware) Roku devices can't connect to it. The solution is to change the Mode to B/G/N. So that's the first place to check. It's possible that Spectrum will need to make the change. In my Comcast modem, they have me locked out of changing the setting myself.
