Wi-Fi & connectivity

[runciter]

I am unsure why, but at my house we just got a new network name and password. The network works with everything else and is discovered by my Roku stick. However I cannot get connected. I am unable to do a system restart. I get the error 009 message. Only 2 options are "ok" and " restart your device". Both just lead back here. "ok" leads back to "choose your network". Neither "other options" go anywhere. "Restart your device" also just leads to the language option, back to the error message. None of the remote buttons do anything. I've unplugged, pressed the restart button on my stick, nothing leads anywhere. Getting very frustrated. Thanks for your time.

@runciter-

There are some router setting issues that can prevent establishing Roku wifi connections. And to make matters worse, some of them can be caused by recently-reported router updates. These have primarily been reported with routers supplied by internet providers (Comcast/Xfinity, Cox, and AT&T so far), but it's possible they could also occur with other internet providers or user-owned routers that have received similar updates.  

ROKU LOCATES NETWORK 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 below 4620) can ONLY receive the 2.4 GHz band and are therefore affected by this.  

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

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</a>. 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.>
