Wi-Fi & connectivity

[Cameron5]

My RCA projector (Roku express) can’t seem to find my network. The 2.4GHz band and 5GHz band are on and the Roku tv we have is also able to find the network. We have factory reset the Roku, reset the router, reset the projector, and the device still can’t find our WiFi network. It seems to find my neighbors just fine. Not sure if this is even fixable or not

If your Roku Express is any model number other than the 3960 (found under Settings/System/About), then you are limited to using the 2.4ghz band.

Go into your router and make sure you have b/g/n enabled under the "Wireless Mode" of your 2.4ghz settings.  Make sure the 2.4ghz is named differently from the 5ghz so you can verify it is actually broadcasting.

Just to test the Express wifi hardware, see if you are able to find and connect to a mobile hotspot (if available to you ) using the 2.4ghz band.  In your hotspot settings, either enable the 2.4ghz band or "maximize compatibility".

@Cameron5-

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 a 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.
