Wi-Fi & connectivity

[teresaterry]

I got a new wi-fi router installed with a new company this week. So far, every other device in my home will connect to the new router, except for my Roku streaming stick device. The Roku is within 40 feet of the new router. When I enter the network password on the Roku streaming stick to connect, I receive error code 014.40

Hi @teresaterry,

Welcome to the Roku Community!

Thanks for reaching out and for letting us know about this issue. If you see this issue occurring, try the following steps below.

1. Restart your router and modem.
2. Relocate your Roku device so it's closer to the router and has a strong signal.

It is possible that the error you received is due to Mac filtering being enabled for your router. This means that your Roku device's Mac ID might have been banned by your ISP from accessing the internet. We suggest contacting your ISP for further assistance in resolving this issue.

Or let us know if the given steps have been taken already.

Thanks,

Rey

It could be the new router set up.

• ROKU LOCATES NETWORK AND REPORTS NETWORK QUALITY BUT CANNOT CONNECT
  Some router updates have changed the router's connection settings on the 2.4 GHz wifi band from b/g/n to just g/n, causing Rokus connecting to the 2.4 GHz wifi band to lose their ability to connect to the network.
  
  Note that, of recent Roku models, non-4K Roku Express/Express+ (model numbers below 3940) and Premiere/Premiere+ (model numbers above 4630) can ONLY receive the 2.4 GHz band and are therefore affected by this.
  
  The solution is to set the router's configuration back to using b/g/n.  See "Reconfiguring Router", below.

Reconfiguring Router
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 any of the above, often a restart of the router (even if other devices are still connecting) followed by a restart of the Roku will 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.
