It was suggested that I start a new thread. I have had my roku box a few years and suddenly it cannot connect to the internet. My other devices work fine. My internet provider said my wi-fi is working fine. I have reset both the internet connection and the roku box & it still doesn’t work. Model #3930 roku express, serial#x004001R30X6, software version 10.5.0-build 4108-AE, error 014.30, wireless connection
Please be advised that Roku Express 3930X is only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Ensure that your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to.
You can also try configuring your router and use wireless channels 1, 6, or 11 which are the preferred channels in North America. Each time you change the wireless channel, you will likely need to apply/save changes before you are prompted to restart the router.
