Your problem may have been caused by a setting on your router which affects some Roku models. The setting changes the router's wifi connection parameters for the 2.4 GHz band from the normal b/g/n to g/n. This has been reported with router updates on equipment from Comcast/Xfinity, Cox, and more recently AT&T, 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 2.4 GHz configuration protocols from the g/n wifi set by the update back to b/g/n. If you don't have access to your router's configuration controls or just don't know how to do this you may have to have your internet provider do it for you.

Thanks to forum user @AvsGunnar for providing the links below to instructions for reconfiguring router settings for the listed internet suppliers. If you can't do this yourself, you may need to contact your internet provider to make these changes for you:

• Xfinity / Comcast → ( https://www.xfinity.com/support/articles/change-wifi-mode-admin-tool-xfinity-xfi ) with a walkthrough ( https://community.roku.com/t5/Network-Wireless-Wired-Connections/Error-014-30-stuck-for-three-days/m...)
  
  
• Cox → (https://www.cox.com/residential/support/managing-your-in-home-network-with-my-wifi.html)
  
  
• AT&T → (https://www.att.com/support/article/u-verse-high-speed-internet/KM1046172). You can select your appropriate router from the drop down menu.

If your problem was not caused by this issue, often a restart of the router (even if other devices are still connecting) followed by a restart of the Roku may allow the connection to be reestablished. Depending on your Roku model and Roku version number you'll find the "System restart" option under either "Settings > System > Power" or "Settings > System", or if more convenient you can just remove the Roku's power for a few seconds and let it restart.
