Having Roku connectivity problems? Get the help and troubleshooting tips you need for Roku wireless connection issues, ethernet connections, and more.
The issue with the 14.30 error on 2.4ghz-only devices (like the Roku 3920 Premiere) is most likely due to a firmware update released by Xfinity/Comcast to its routers that is mishandling a speed protocol setting. You will need to change a "Mode" setting within your Xfinity router to reflect b/g/n setting, rather than g/n setting.
The below instructions and images/screenshots are from a TG1682G router. (5 minute fix)

Basically, all you really have to do is verify that your 2.4ghz wi-fi band is enabled and broadcasting, and that you switch your 2.4ghz band Mode/protocol to b/g/n.
Either launch your Xfinity app or type in 10.0.0.1 in a web browser that is connected to the same network as your router. Your Username = admin, and your Password = password.
Then look on left of Screen for Gateway selection. From there click/navigate to Gateway...Connection...Wifi. Then select Edit on your 2.4ghz Frequency Band. From there a screen should appear with various Wireless Configuration Settings. This is the screen where you will need to verify that your 2.4ghz band is Enabled and the 2.4ghz SSID (network name) is Broadcasting, and where you switch your Mode from g/n to b/g/n. After verifying and making changes, press SAVE SETTINGS, and then restart both your router and your Roku device.
You really should be good to go from there.
