My device suddenly disconnected from my wifi and cannot find it anymore after several attempts and even factory setting it. Bought it only over a month ago. What do I do? Roku Express (3930, 3931 series)
You have the Roku Express and it is a single-band wireless device which means it only supports a 2.4 GHz connection. Your Roku Express will not recognize the 5Ghz network. You need to make sure that your 2.4 GHz network is active by using your mobile phone and check if you can detect the 2.4 GHz network. We also suggest you reach out to your Internet Service Provider or ISP for assistance in checking if the 2.4 GHz network is active and not hidden.
