I bought a roku express 4K+ and I tried to set up the device and when I tried to connect the roku to my hotspot that didn’t work . It said that the wireless connection is ok but the internet connection isn’t ok and I restarted the roku but it was the same. I tried many times and that didn’t work The info of my roku is: Model: 3941X - roku express 4K + serial number : X016008C8CS2 (S07P21AC8CS2) software versión : 9.4.0 build 1042-CR timestamp: 2021-02-13T00:32:10Z
As @DBDukes stated, Roku devices should be on the latest OS 10.5. Can you please verify that the current OS on your Roku device is currently running? You can find this information in Settings > System > About.
