Checked 1 November 2026. Roku OS and Roku Support pages as of 2026, for current Roku streaming players, Streaming Sticks and Roku TV models. Some features depend on the model and on Roku OS 12.0 or later.

Wi-Fi it needs

Every current Roku streaming device supports 5 GHz on the non-DFS channels: 36 to 48 and 149 to 165. Whether it can use the DFS channels in between depends on the model.

  • DFS channels: some models also use channels 50–64 and 100–144, which needs Roku OS 12.0 or later. Roku’s advanced networking page lists which models can.
  • What a model without DFS does: it may use the same network’s 2.4 GHz band if available. To use 5 GHz, choose a non-DFS channel supported in your region.
  • Mesh routers: Roku notes that a mesh system may combine 2.4 and 5 GHz into a single network name.
  • Channels: Roku says automatic channel selection can cause intermittent or slow connections. On 2.4 GHz it recommends channels 1, 6 or 11.
  • Passwords: they’re case-sensitive. The router’s label often shows the default name and password.
  • Ethernet: some Roku players and TVs have an Ethernet port, and some players support a USB Ethernet adapter.
  • IPv6: Roku’s June 2026 list identifies models such as 3800X, 4800X and 9100X as supporting IPv4 and IPv6 together. A later support article lists some older models without IPv6; check the current list for your model.

To see which channel your Roku uses, go to Settings › Network › About and read Wireless channel.

Set it up

  1. Connect the player to the TV, or switch on the Roku TV, and follow the on-screen setup.

  2. When asked how to connect, select Wireless.

  3. Pick your network; if it’s missing, select Scan again to see all networks.

  4. Enter the password and select Connect.

  5. Follow the on-screen steps to finish setup and activate it with your Roku account.

Change the network later

  1. Press Home, then go to Settings › Network › Set up connection.

  2. Choose Wireless or Wired, then pick the network and enter its password.

Use a phone’s hotspot

With no other Wi-Fi, a Roku can join a phone’s hotspot like any network. Roku warns that streaming and software updates can use a lot of mobile data.

How much data it uses

Roku gives the download speed each quality needs, which it checks with Settings › Network › Check connection.

Roku publishes no data-use figures per hour or per day. Streaming apps such as Netflix may set their own speed minimums.

QualityDownload speed Roku lists
Standard definition3 Mbps
High definition5 Mbps
4K Ultra HD25 Mbps or more

Bandwidth Saver

To protect data caps, Roku’s Bandwidth Saver stops streaming after four hours with no remote or app activity, unless you select Keep streaming. Turn it off in Settings › Network › Bandwidth saver.

Guest, hotel and dorm Wi-Fi

Hotel, university and some public networks show a sign-in page before they let a device online. On supported Roku models, Hotel & Dorm Connect uses a phone or computer to complete sign-in.

  1. Before you travel, activate the Roku at home and check for a software update.

  2. At the hotel or dorm, press Home and go to Settings › Network › Set up new wireless connection.

  3. Choose the hotel or dorm network, or select Scan again to see all networks.

  4. Once it connects, select I am at a hotel or college dorm.

  5. Complete the sign-in steps shown on the TV, using a phone or computer with a web browser.

  6. Within a few minutes, check that Network shows the network and a status of Connected; if not, select Try again.

Why the Roku app can’t find it

  • Roku recommends checking that the phone and Roku use the same network name and band.
  • A wired Roku on a different network from your phone may not be reachable. Check the network configuration.
  • On iPhone, turn on Settings › Roku › Local Network, and turn off any VPN on the phone.
  • On the Roku, turn on Settings › System › Advanced system settings › Control by mobile apps.
  • In the app, Connect manually takes the Roku’s IP address from Settings › Network › About.

When it won’t connect

Roku associates these codes with connection problems. Some appear under more than one cause, so use the checks below rather than assuming a single diagnosis.

  1. Check you chose the right network and typed the right password.

  2. Connect a phone or laptop to the same network; if it fails too, contact your provider.

  3. Restart the Roku from Settings › System › Power › System restart, or unplug it for 10 seconds.

  4. Unplug the modem and router for 10 seconds, plug them back in and wait for them to start.

  5. Run Settings › System › Advanced system settings › Network connection reset, then reconnect.

  6. If it still fails, join a phone’s hotspot; if that works, the home network is the problem.

Factory reset

As a last resort, go to Settings › System › Advanced system settings › Factory reset (on a Roku TV, Factory reset everything). It erases all settings and apps.

When it keeps going offline

  1. Open Settings › Network › About and read Signal strength: Poor or Fair needs fixing.

  2. Move the Roku and router closer, and out of cabinets or enclosed spaces.

  3. Raise both higher, and point the router’s antennas in different directions.

  4. For a stick behind the TV, use Roku’s free HDMI extender from my.roku.com/hdmi.

  5. Plug the Roku into a wall socket, not the TV’s USB port, if it shows a low-power warning or restarts.

  6. Switch to 5 GHz if your Roku supports it, and choose a less crowded channel by hand.

  7. Run Settings › Network › Check connection again after each change.

Roku also suggests pausing large downloads on other devices, keeping the router away from microwaves, cordless phones and baby monitors, and trying Ethernet. If the router is over five years old, it suggests a newer one, such as a mesh or dual-band system.

Questions

Can a Roku connect to hotel or dorm Wi-Fi?

On supported models, use Hotel & Dorm Connect. Choose the network, select I am at a hotel or college dorm, then sign in on a phone or computer. The Roku must be activated first.

Why can’t my Roku see my 5 GHz network?

First check whether your model supports 5 GHz. Some models cannot use DFS channels 50–64 and 100–144.

What does Roku error 14.40 mean?

A wrong Wi-Fi password. Check it, remembering that it’s case-sensitive, and try again.

How fast does my internet need to be for a Roku?

Roku lists 3 Mbps for standard definition, 5 Mbps for HD and 25 Mbps or more for 4K.

See your network from your Mac

Kilobat is a Mac menu-bar app with a CLI and an MCP server for AI agents. It lists the devices on your Wi-Fi and says when a new one joins, keeps a history of the router’s and the internet’s health, scans nearby channels, and shows which app on your Mac is using the network. Read the docs.
