Re: Roku device connection with Wi-Fi


If you have a cable ISP (Xfinity/Comcast, Cox, or AT&T), you may have to verify that your 2.4ghz band is configured to use the b/g/n protocol.

Your Express can only see and use the 2.4ghz band so this is first setting to look at, as well as verifying that your 2.4ghz band is actually on/enabled and broadcasting.  Increasingly, these cable ISP routers are being locked down (managed by ISP, not user-editable/configurable) so may have to contact them and let them know you need your "2.4ghz Wireless Mode to be set to b/g/n".

Here are instructions for various cable ISP in case you have a model that is still configurable.  If the above is not applicable to you, post back with more details of your issue, including Roku model number (Settings/System/About), your router model numer, and your ISP.

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.


You can try connecting to a mobile hotspot if available to you on the 2.4ghz band to verify that your Express units are capable of making a connection.  This should help you verify that a network (router) setting is your culprit.
