Wi-Fi & connectivity

[Tngirl99]

Roku Premier has suddenly quit connecting to the network. It will not scan for networks either, also tried other ways to get it to connect. No luck! Did system/hard reset several times and finally got the Issue report tracker ID 31-155-408. This Roku has only been in use for 5 months and was bought new. Any help with this is greatly appreciated!

What is your model number and who’s your ISP?

[Tngirl99]

Model number is 3920RW and provider is Spectrum. I also tried to Hotspot with Verizon and it didn't work either. It's not recognizing any network.

@Tngirl99  Your Roku 3920 is a single band device. It’s only connects to the 2.4GHz WiFi b,g,n signal. You will need to reconfigure your Spectrum modem to work on that signal

Unfortunately, when a Roku device fails to see/locate any available networks and is unable to connect to a hotspot normally indicated an internal failure.  Normally, replacement of the device is usually required.  Yours should qualify for warranty replacement since under 1-year.

However, if the Roku device is seeing other networks (neighbors, etc) to connect to but just is not seeing yours, then possibility exists that your 2.4ghz band is either turned off/disabled or misconfigured.  Verify that your 2.4ghz band is actually On/Enabled.  Is the Roku device seeing "any" networks at all after rebooting both the Router and your Roku device.

Additionally, some Roku devices produce different behaviors when encountering a power supply issue.

To address power supply issue..

1. Try using power supply adapter directly connected to wall outlet rather than TV USB port.

2. Try using another power adapter (cell phone power adapter 5v 1 amp)

3. Try using another power cable (cell phone power cable w/ micro USB connector on device end)

Feel free to post back with an update or if you have any other questions.

It isn't seeing any networks to connect to.

"It isn't seeing any networks to connect to."

That would normally indicate an internal device failure, unfortunately - especially If checking into the power supply didn't help resolve it.  Warranty Replacement should take care of you. (Warranty step by Step - https://support.roku.com/article/208757058)
