Re: Unable to connect to wireless network

Hi @Jennersxoxo

Thanks for reaching out here in the Community!

Could you tell us who is your internet service provider? If it's Comcast or ATT, we would recommend changing your router settings for the 2.4 GHz band from g/n to b/g/n, as customers have stated that this helped resolve their issue.

If still no dice, please reply here with the model number of your Roku device. This can be found in Settings > System > About.

We look forward to your response.


All the best,
Kariza

Re: Unable to connect to wireless network

@Jennersxoxo-

Bear with me, as you haven't given us enough information to narrow down the possible issues.

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 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. The solution is to set the router's configuration back to using b/g/n.  See "Reconfiguring Router", below.
     
  • ROKU CANNOT FIND LOCAL WIFI NETWORK AT ALL
    If you have one of the following situations, see "Reconfiguring Router", below.
    To check your Roku model and model number use Roku menu path Settings > System > About.
     
    A) Some recent router updates have turned off dual band routers' use of the 2.4 GHz band. Some Roku models, notably Roku Express/Express+ (model numbers below 3940) and Premiere/Premiere+ (model numbers above 4620), are lower end units with single band Wi-Fi radios that only support the 2.4 GHz band. They, and many other devices of all sorts that are 2.4 GHz only, can't even see the 5 GHz band, let alone connect to it. If you have 2.4 GHz only Roku model and a dual band router with both 2.4 and 5 GHz bands, be sure the router's 2.4 GHz band is turned on.
     
    B) In the 2.4 GHz WiFi band, all Rokus support channels 1-11, as are used in North America. If your router supports 2.4 GHz channels outside this range make sure your router is set to use a channel in this range and that you aren't using an auto setting that could select channels outside this range.
     
    C) Rokus with dual-band wifi radios can connect to the 5 GHz wifi band in two ranges of channel numbers, 36-48, and 149-165.  Specifically they do NOT support the "DFS" channels between these4 two ranges.  If your router supports 5 GHz channels outside these two supported ranges make sure your router is set to use a channel within these ranges and that you aren't using an auto setting that could select channels not in these ranges.

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:

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.
