The most common reason your Roku loses internet is that it's too far from your router or something is blocking the signal

A Roku that won't connect to the internet usually sits in one of three situations: it never connected in the first place, it connected once and then dropped, or it connects but keeps disconnecting. The cause is almost always distance, interference, or a password problem — not a broken device. Start by checking whether your router is actually broadcasting (look for a light on the front), then move your Roku closer to it temporarily to see if that fixes the problem. If it does, you know the issue is signal strength, not your account or settings.

If moving it closer doesn't help, the next step is to forget the network on your Roku and reconnect from scratch, because a corrupted saved password is the second most common culprit. After that, you'll check whether your router itself is working properly and whether your Roku's WiFi hardware is functioning. Most of these problems take five to ten minutes to solve once you know which one you're facing.

Key Takeaways

  • Distance and physical obstacles between your Roku and router cause most connection failures — try moving the Roku within six feet of the router to test this first.
  • Forgetting the network on your Roku and re-entering your WiFi password from scratch fixes most cases where the device connected before but now won't.
  • If your Roku connects but keeps dropping, the problem is usually interference from other devices or a weak signal, not your internet service itself.
  • Restarting your router by unplugging it for 30 seconds often fixes connection problems faster than troubleshooting the Roku itself.

Check the distance between your Roku and router

WiFi signals weaken as they travel through walls, floors, and distance. A Roku sitting in a bedroom on the opposite side of your house from the router may be just barely in range — it connects sometimes, drops frequently, or refuses to connect at all. The quickest test is to move your Roku to within six feet of the router, even if that means setting it on top of the router temporarily, and try connecting again.

If it connects when ready when close, you've found your problem. The solution is either to move the router to a more central location in your home, move the Roku closer, or add a WiFi extender or mesh system to strengthen the signal in that room. If it still won't connect even when sitting next to the router, move on to the next section — the problem is not distance.

Forget the network and reconnect with your password

When a Roku has connected to your WiFi before but suddenly won't, the saved password on the device is often corrupted or outdated. The fix is to delete that saved network from the Roku's memory and enter your password fresh. On your Roku remote, press the Home button, then go to Settings > Network > WiFi > Manage networks. Find your network name in the list and select it, then choose "Forget". Your Roku will no longer remember that network.

Now go back to Settings > Network > WiFi and select your network name again. When prompted, enter your WiFi password exactly as it is — passwords are case-sensitive, so "MyPassword123" is different from "mypassword123". If you're not sure what your password is, check the sticker on the back or bottom of your router, or log into your router's settings through a computer or phone to see or reset it. After you enter the password, wait 30 seconds for the Roku to connect.

Restart your router

Your router can develop temporary glitches that prevent any device from connecting, even though the router itself is working. The fix is straightforward: unplug the router's power cable, wait 30 seconds, and plug it back in. While the router is restarting (this takes about two minutes), don't try to connect anything to it. Once the lights on the front of the router stop blinking and settle into a steady pattern, try connecting your Roku again.

If restarting the router fixes the problem, you're done. If the Roku still won't connect after the router has fully restarted, the issue is either with the Roku itself or with how it's configured. Move to the next section.

Check whether other devices can connect to your WiFi

Before you assume your Roku is broken, confirm that your WiFi network itself is working. Try connecting a phone, laptop, or tablet to the same network. If other devices connect without trouble and can browse the internet, your router and internet service are fine — the problem is specific to the Roku. If no devices can connect, or if they connect but have no internet, the problem is your router or your internet service, not the Roku.

If other devices can't connect either, restart your router again and check whether your internet service is working by looking at the lights on your modem (the device the router plugs into). If the modem's lights are off or red, contact your internet provider — the problem is on their end. If the modem lights are normal but devices still can't connect, your router may need a factory reset, which is covered in the next section.

Factory reset your Roku if nothing else works

If your Roku won't connect even when sitting next to the router, other devices can connect fine, and you've re-entered the password correctly, the Roku's WiFi hardware or software may be damaged. A factory reset will erase all your settings and sign-outs, but it often fixes connection problems. On your Roku remote, press Home, then 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 take you through the setup process as if it were brand new. When you reach the network screen, select your WiFi network and enter your password. If it connects this time, the problem was a corrupted setting that the reset cleared. If it still won't connect after a factory reset, the Roku's WiFi hardware is likely faulty and the device may need to be replaced.

Reduce interference from other devices

If your Roku connects but keeps dropping the connection every few minutes, interference from other devices is often the cause. Microwaves, cordless phones, baby monitors, and some wireless speakers all broadcast on the same 2.4 GHz frequency that most Rokus use. If you have any of these devices near your router or Roku, move them away or turn them off temporarily to see if the connection stabilizes.

You can also try changing your router's WiFi channel through its settings page. Most routers default to a channel that may be crowded in your area. Log into your router through a computer or phone (usually by typing the router's IP address into a web browser — check the router's manual or sticker for this address), find the WiFi settings, and try switching to a different channel, such as channel 1, 6, or 11 on the 2.4 GHz band. After changing the channel, reconnect your Roku and see if the drops stop.

Frequently Asked Questions

Why does my Roku connect to WiFi but then lose internet after a few minutes?

This usually means your Roku is at the edge of your router's range and the signal is too weak to stay stable. Try moving the Roku closer to the router. If that doesn't help, interference from other devices like microwaves or cordless phones may be the cause — move those away from your router or Roku. Restarting your router can also help if it's overheating or has a temporary glitch.

My WiFi password is correct, but my Roku still won't connect. What do I do?

Forget the network on your Roku and re-enter the password from scratch, because the saved password may be corrupted. If that doesn't work, restart your router by unplugging it for 30 seconds. If your Roku still won't connect after both of those steps, try a factory reset — go to Settings > System > Advanced system settings > Factory reset.

Can I connect my Roku with an ethernet cable instead of WiFi?

Most Roku models only have WiFi, but some higher-end models like the Roku Ultra have an ethernet port on the back. If yours has one, you can plug an ethernet cable directly from your router to the Roku. This bypasses WiFi entirely and is more stable, though it requires running a cable to where your Roku sits.

How do I know if my router is the problem and not the Roku?

Try connecting a different device — a phone, laptop, or tablet — to the same WiFi network. If it connects and works fine, your router is working and the problem is with the Roku. If other devices also can't connect, the problem is your router or internet service, not the Roku.

Should I use the 5 GHz or 2.4 GHz WiFi band for my Roku?

Most Rokus only support 2.4 GHz, so that's your only option. If your router broadcasts both bands, make sure your Roku is connecting to the 2.4 GHz network, not the 5 GHz one. Check your router's settings or the network name — 5 GHz networks sometimes have "5G" in the name to distinguish them.
