Wi-Fi & connectivity

[aaronj]

My express 4k (not sure if it’s a + or not) flashes blue on the front of the device. It has randomly stopped connecting to our wifi even though it shows our wifi strength as excellent. We have tried to restart both the roku, tv, and wifi and nothing is working. I also tried to factory reset the roku and it still won’t connect to internet. It recognizes our wifi but won’t connect.

Hey @aaronj

Thanks for letting us know about the issue you're experiencing.

Please be advised that Roku Express (3930) 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 check your device model by navigating to Settings > System > About.

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.

Let us know if this works for you!

All the best,
Kariza

Your problem may have been caused by a recent update to your router which affects some Roku models. The update changed the router's wifi connection parameters from b/g/n to g/n.  This has been reported lately with equipment from Comcast/Xfinity and Cox, but there may be others.

Affected users report the Roku identifies the local network as available and rates the connection quality, but will not then connect. The fix is to switch the router configuration protocols from the g/n wifi that was set by the update back to b/g/n. If you don't have access to your router's  configuration controls you may have to have your internet provider do it for you.
