Won’t connect to internet

Model # 3930x - Roku Express

Serial # X004007G1WWO

Roku won’t connect to internet. My wireless internet connection is strong  and working on all other devices. Have rebooted modem/router & Roku several times. It did this a week ago. I rebooted everything, it started working again. Now, nothing works. Help, please.

Re: Won’t connect to internet

The Roku you have is the base model Express. It can only connect to the 2.4GHz WiFi. Do you need to configure your router or modem to use the 2.4GHz network. I feel bought name model hire Roku those are dual band

Re: Won’t connect to internet


There are a couple router setting issues that can prevent establishing Roku wifi connections. And to make matters worse, both 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 ATT so far), but it's possible they could also occur with other internet providers or user-owned routers that have received updates.

    Some router updates have changed the router's connection settings from b/g/n to just g/n, causing some 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.
    A) Some router updates have turned off the 2.4 GHz wifi band on the router leaving only the 5 GHz band in operation. Roku Express/Express+ (not the relatively new Express 4K/4K+ models 3940/3941) 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 one of these Roku models 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) All Rokus, both single- and dual-band, support channels 1-11 in the 2.4 GHz WiFi band, 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 it isn'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. If your router supports 5 GHz channels not in these two 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 outside these ranges..

    If you need to make configuration changes on equipment supplied by your internet provider but you have no access to its settings, you may need to request your internet provider to make the changes for you.</p>

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 may allow the connection to be established. 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 unplug the Roku from its power source for a few seconds and let it restart.

Note that for a Roku TV (i.e. one with Roku capability built in) that has "Fast start" enabled, turning the tv off then on does not give a complete restart. Unplug it from its power source for a few seconds or use the menu path indicated above.
