The error 014.40 on Roku (and the related 14.41) signifies a “Wireless Setup Failed” message, meaning your device cannot authenticate with your Wi-Fi network. This is usually due to a password typo or router security mismatch.
- Verify Your Password: Double-check your Wi-Fi password. It is case-sensitive, and a single typo will instantly trigger this error.
- Change Router Security to WPA2: Newer WPA3 “transition mode” settings on routers frequently cause authentication loops for Roku TVs. Log into your router and force WPA2-Personal (AES) security.
- Reset Network Connections: Go to Settings > System > Advanced system settings > Network connection reset. Reboot the TV and try connecting again.
You just brought home a new Roku TV or you’re setting up your streaming stick in a new apartment. You select your Wi-Fi network, punch in the password, and hit connect. Instead of a green checkmark, you get a glaring red “X” and the frustrating error 014.40 on your Roku (sometimes appearing as 14.40 or 014.41).

This specific code is Roku’s way of saying, “I can see the router, but the router won’t let me in”. It is not an internet outage; it is a localized authentication failure on your home network. Because Roku devices (especially older models and budget TVs) have specific Wi-Fi requirements, modern smart routers sometimes confuse them. Below, we break down exactly how to bridge that gap and get your device online.
Common Triggers for Roku Error 014.40
Before you dive into complex router settings, it is important to rule out the simple stuff. This error is almost always triggered by one of the following issues:
- Incorrect Password Entries: Wi-Fi passwords are case-sensitive. Using a lowercase “L” instead of an uppercase “I” on the on-screen keyboard is a very common mistake.
- MAC Filtering Blocks: If you or your ISP have “MAC Filtering” enabled on your router, it acts like a bouncer at a club, actively denying the Roku’s connection attempt even with the correct password.
- Band Steering Issues: Many modern mesh routers combine 2.4 GHz and 5 GHz bands into one network name (SSID). Roku TVs prefer stable 2.4 GHz connections and can fail authentication when the router tries to force them onto the 5 GHz band.

Step-by-Step Fixes for Wireless Setup Failures
If you have double-checked your password and you’re still getting the error, use this troubleshooting table to adjust your network settings.
| Troubleshooting Step | Why It Works | How to Do It |
|---|---|---|
| 1. Network Connection Reset | Clears cached network profiles and stale authentication data that might be causing a loop. | Settings > System > Advanced system settings > Network connection reset. Then reboot the TV. |
| 2. Switch Security to WPA2 | Roku devices often fail the “handshake” process with newer WPA3 mixed-mode security. | Log into your router admin page. Find Wireless Security settings and change from WPA3/WPA2 Mixed to strictly WPA2-Personal (AES). |
| 3. Split 2.4 / 5 GHz Bands | Provides a dedicated, stable 2.4 GHz signal that Roku devices prefer for consistent connectivity. | In your router settings, disable “Smart Connect” and give your 2.4 GHz band a separate name (e.g., “HomeWifi-2G”). |
When to Resort to a Factory Reset
If you have optimized your router settings and successfully cleared the network cache on the TV, but the 014.40 error persists, the Roku OS firmware itself might be deeply corrupted. A full factory reset is the “nuclear option.” This will wipe all of your apps, login data, and customized settings, returning the TV to its out-of-the-box state.
To do this, navigate to Settings > System > Advanced system settings > Factory reset. Before you wipe your device, however, you may want to review our guide to fixing smart TV Wi-Fi drops to ensure your router isn’t physically too far away. If your Roku is still under warranty and refuses to connect even after a reset, you should contact official Roku Support for a potential hardware replacement.
TL;DR Summary
- Roku Error 014.40 / 14.41 means the device failed to authenticate with your router during wireless setup.
- Carefully retype your Wi-Fi password, utilizing the shift key for capital letters; passwords are case-sensitive.
- Perform a “Network Connection Reset” in the Advanced System Settings before attempting a full factory reset.
- Log into your router and change your wireless security settings to strictly WPA2-Personal (AES), as WPA3 mixed modes confuse Roku devices.
- If your router combines bands, try splitting them and forcing the Roku to connect to the dedicated 2.4 GHz network for better stability.
