You may see one of these error codes while setting up your TCL Roku TV or during normal streaming. Use the matching section below to get back online.

Note: Settings may vary by model and software.

Start here (quick checks that help most codes)

• Check if your internet is actually working on a phone/computer on the same network. (If nothing connects, it’s likely an ISP or router outage.)
• Restart your TCL Roku TV: Home > Settings > System > Power > System restart > Restart.
• Restart your modem/router (unplug power for ~30–60 seconds, plug back in, wait for it to fully reconnect).
• If you’re on Wi-Fi, move the TV (or router) closer and reduce obstacles (walls, cabinets).

Error Code 009

Meaning: Your TV can connect to the router, but there’s no internet access.

Try this:

• Confirm other devices can browse the internet on the same network. If they can’t, contact your ISP.
• If other devices do have internet, restart the TV (steps above).
• If it still happens, restart the router/modem and then try connecting again.

Common causes:

• Temporary ISP outage
• Router lost upstream connection
• Captive portal networks (hotel/dorm/public Wi-Fi) that require a web sign-in (see tip near the end)

Error Code 012 (Ethernet)

Meaning: Wired (Ethernet) connection issue.

Try this:

• Make sure the Ethernet cable is fully seated in the TV and router.
• Try a different Ethernet cable (or a different router port if available).
• Restart the TV and router/modem.
• If you have Wi-Fi available, temporarily switch to Wi-Fi to confirm internet service is working.

Error Code 013 (Ethernet)

Meaning: Another wired network error.

Try this:

• If other devices can connect to the internet, restart the TV.
• Unplug and reconnect the Ethernet cable at both ends.
• Restart the router before contacting your ISP.

Error Code 014

Meaning: The TV failed to connect to Wi-Fi (often network selection issues).

Try this:

• Double-check you selected the correct Wi-Fi network name (SSID).
• Re-enter the password carefully (passwords are case-sensitive).
• Restart TV and router, then try connecting again.

Error Code 014.20 / 014.30 / 014.50 (Weak Wi-Fi signal)

Meaning: Wi-Fi signal is not strong enough to complete the connection.
(You may also see other “14.xx” weak-signal codes on some Roku software versions.)

Try this:

• Move the TV closer to the router, or move the router higher and more open (avoid cabinets).
• Restart both router and TV.
• If your router has both 2.4 GHz and 5 GHz, try the other band:
• 2.4 GHz = longer range (often better through walls)
• 5 GHz = faster but shorter range
• If the TV previously connected but won’t now, do a Network Connection Reset (see “Advanced fix” below).
• If problems continue after improving signal, you may need a factory reset as a last step.

Error Code 014.40 / 014.41 (Password or router restrictions)

Meaning: Usually an incorrect Wi-Fi password or a router setting that blocks the TV.

Try this:

• Confirm you selected the correct network name (SSID).
• Re-enter the password carefully (case-sensitive).
• Check router settings such as MAC Address Filtering / Access Control. If enabled, add the TV’s Wireless MAC Address to the allowed list.

Error Code 016

Meaning: You tried to launch a channel/app, but the TV lost the network or internet connection.

Try this:

• Select Set up connection on-screen and reconnect.
• Restart the TV and router.
• If it happens repeatedly, check Wi-Fi signal strength and consider the “Advanced fix” below.

Error Code 017

Meaning: The TV detects a poor/weak wireless signal.

Try this:

• Improve placement of the TV/router and reduce obstacles.
• Restart the TV and router.
• If possible, use Ethernet for the most stable connection (models with LAN port).

Error Code 018

Meaning: Internet bandwidth is too low for reliable streaming.

Try this:

• Pause downloads/streams on other devices to reduce congestion.
• Restart modem/router and try again.
• If you consistently see this, check your subscribed internet speed with your ISP and consider upgrading if needed.

Advanced fix (helps stubborn Wi-Fi problems without a full factory reset)

If your TV used to connect fine but now won’t, try a Network Connection Reset:

Home > Settings > System > Advanced system settings > Network connection reset > Reset connection
Then reconnect to Wi-Fi again.

Find your Wireless MAC Address (for MAC filtering)

• Press Home
• Go to Settings
• Go to Network
• Select About
  Your MAC address is listed next to Wireless MAC address.

Tip for hotel/dorm/public Wi-Fi

If your network requires a web login page, standard setup may fail. Roku has a “Hotel and Dorm Connect” option after activation for these networks (workarounds may apply if the TV has never been activated).
