Re: Roku not connecting to wifi

@Acraig01-

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.  

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. 

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 situations below, see the "Reconfiguring Router" section below. 

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 below 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) All 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.  Many specifically do NOT support the "DFS" channels 50-64 and 100-144.   

NOTE: Roku added support for DFS channels for those models equipped with Realtek 13xx processor chips.  Per the Wikipedia Chart at https://en.wikipedia.org/wiki/Roku#Feature_comparison, those models are:  

•   Streaming Stick 4K/4k+ (3820/3821)  

•   Express 4K/4k+ (3940/3941)  

•   Ultra/Ultra LT (4800/4801) 

If your router does not support DFS channels make sure it is set to use a channel within the 36-48 or 149-165 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: 

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.>
