Your Roku loses the internet connection for a few specific reasons, and most are fixable in minutes

A Roku that won't connect to WiFi usually means one of three things: your router isn't broadcasting the network name, your Roku has the wrong password, or something is blocking the signal between them. Less often, the Roku's WiFi chip itself has failed. The good news is that the first three are straightforward to test and fix yourself, and you'll know within a few minutes whether you're dealing with something that needs a replacement device.

The fastest way to start is to check whether other devices in your home can reach the same WiFi network right now. If your phone, laptop, or tablet connects without trouble, the problem is almost certainly with the Roku, not your router. If nothing connects, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully boot.

Key Takeaways

  • Check whether other devices connect to your WiFi first—if they do, the problem is with the Roku, not your router.
  • The most common fix is re-entering your WiFi password on the Roku, because the device may have stored it incorrectly.
  • Move the Roku closer to your router temporarily to rule out signal strength as the cause.
  • If the Roku connects briefly and then drops, restart your router and check whether other devices are using most of your bandwidth.
  • A factory reset erases all settings and returns the Roku to its original state, which fixes software glitches but requires you to set up the device again from scratch.

Check your WiFi password and network name on the Roku itself

Go to Settings on your Roku home screen, then select Network. You'll see the name of the network your Roku is trying to connect to. If that name doesn't match the network name you see on your phone or laptop, your Roku is looking for the wrong network—this happens when you have two networks broadcasting from the same router (usually a 2.4 GHz and a 5 GHz band) and the Roku picked the wrong one.

If the network name is correct, select it and choose Forget. Then go back to Network and select Set up connection. When the Roku shows you a list of available networks, pick the one you use on your other devices. Enter your password exactly as it appears—Roku passwords are case-sensitive, so "MyPassword" is different from "mypassword". If you're not sure of your password, check it on a device that's already connected: on most phones, go to Settings > WiFi, tap the network name, and select Share Password to see it.

Move the Roku closer to your router to test signal strength

WiFi signal weakens with distance and through walls. If your Roku is in a bedroom two rooms away from your router, try moving it to within six feet of the router temporarily. If it connects when ready, you've found the problem: either the Roku needs to be closer to the router permanently, or you need to move your router to a more central location in your home.

If moving it doesn't help, move it back to where it was. This test straightforward tells you whether distance is the issue. If the Roku still won't connect even next to the router, the problem is something else.

Restart your Roku and your router in the right order

Unplug your Roku from power and leave it unplugged for 30 seconds. Plug it back in and wait for the Roku logo to appear on your screen—this takes about one minute. While the Roku is starting up, unplug your router, wait 30 seconds, and plug it back in. Wait another two minutes for the router to fully boot before trying to connect the Roku.

This order matters because it gives your router time to be ready when the Roku looks for networks. If you restart them at the same time, the Roku may start searching before the router has finished booting, and it won't find anything.

Check whether other devices are using all your bandwidth

If your Roku connects but then drops after a few minutes, or if it connects but streams very slowly, another device on your network may be using most of your bandwidth. Video calls, large downloads, or streaming on multiple devices at once can overwhelm a router, especially older ones or ones far from where you're using them.

Ask anyone else in your home to pause what they're doing for a moment, then try the Roku again. If it works better when nothing else is running, you've found the cause. The fix is either to upgrade your internet plan, move your router to a more central location, or use your Roku during times when fewer people are online.

Factory reset the Roku if nothing else works

A factory reset erases all your settings and returns the Roku to the state it was in when you first took it out of the box. This fixes software glitches that prevent the Roku from connecting, but it also means you'll have to set up the device again—sign in to your Roku account, reconnect to WiFi, and reinstall any channels you use.

To factory reset, go to Settings > System > Advanced system settings > Factory reset. The Roku will ask you to confirm. Select Factory reset again. The device will restart and show you the setup screen you saw the first time you turned it on. Follow the on-screen steps to reconnect to your network.

If the Roku still won't connect after a factory reset, the WiFi hardware inside the device has likely failed. At that point, the device needs to be replaced.

When to contact Roku support or your internet provider

Contact Roku support if you've tried all the steps above and the Roku still won't connect, especially if it connected fine before and suddenly stopped. They can check whether there's a known issue with your Roku model or whether a recent software update broke something.

Contact your internet provider if other devices also can't connect to WiFi, or if they connect but are very slow. This suggests a problem with your router or internet service, not the Roku. Your provider can run a speed test from their end and tell you whether your connection is working as it should.

Frequently Asked Questions

Can I use an ethernet cable instead of WiFi?

Some Roku models have an ethernet port on the back, but most do not. Check your device's specifications or look at the back of your Roku. If there's a port labeled "Ethernet" or "Network", you can plug in a cable. If not, WiFi is your only option.

Why does my Roku keep dropping the connection?

Constant disconnections usually mean either weak signal (move the Roku closer to the router), too many devices using bandwidth at once (pause other activity), or an overheating router (make sure it has space around it and isn't in a hot closet). Restart both devices in the order described above. If it still drops, try connecting to the 2.4 GHz band instead of 5 GHz, as 2.4 GHz travels farther through walls.

Do I need to update my Roku's software to fix connection problems?

Roku updates automatically when connected to WiFi, so you can't update if you're not connected. However, if your Roku connected before and suddenly stopped, an update may have caused it. Try the factory reset first. If that doesn't work, contact Roku support to ask whether a recent update is known to cause connection issues.

What if my router is very old?

Routers older than five or six years may not work well with newer Roku models, especially if they don't support 5 GHz WiFi or have weak signal strength. Try connecting to the 2.4 GHz band if your router has one. If the Roku still won't connect, your router may need to be replaced.
