Roku Error Code 056 — What It Means & How to Fix It

What Does This Error Mean?

Roku error code 056 means your Roku connected to a Wi-Fi network but could not authenticate — it got rejected when it tried to prove it was allowed to join. This usually happens when the Wi-Fi password was recently changed, the router's security settings were updated, or the Roku's stored network profile has become corrupted. The fix almost always involves re-entering the correct Wi-Fi password or forgetting the network and reconnecting fresh.

Affected Models

Roku Express
Roku Streaming Stick
Roku Ultra
Roku TV
Roku Premiere

Common Causes

The Wi-Fi password was changed on the router but not updated on the Roku
The router's wireless security protocol was changed (for example from WPA2 to WPA3) and the Roku does not support the new protocol
The Roku's saved network profile is corrupted and is sending wrong credentials
MAC address filtering is enabled on the router and the Roku's MAC address is not on the allowed list
The router's DHCP server is not assigning an IP address to the Roku correctly

How to Fix It

Re-enter your Wi-Fi password on the Roku. Go to Settings > Network > Set up connection > Wireless. Select your network and carefully type the password again. Passwords are case-sensitive.

This is the most common fix. Even if you think the password is right, try re-entering it. A single wrong character — especially a capital letter or number — causes authentication to fail.
Restart both your Roku and your router. Unplug the router from power, wait 30 seconds, and plug it back in. While the router restarts, also restart the Roku via Settings > System > System restart.

A router restart clears its connection table and forces a clean new connection attempt. This resolves many authentication errors that are not caused by an incorrect password.
Forget the network and reconnect from scratch. On the Roku go to Settings > Network > Set up connection > Wireless. Choose your network and select 'Forget network' if the option appears, then reconnect and re-enter your password.

Forgetting the network deletes the corrupted saved profile. Reconnecting creates a fresh profile with correct credentials.
Check your router for MAC address filtering. Log in to your router's admin page (usually at 192.168.1.1 or 192.168.0.1 in a web browser). Look for a setting called MAC filtering or Access Control. If it is enabled, add your Roku's MAC address to the allowed list.

Your Roku's MAC address is found at Settings > Network > About. It is a series of letters and numbers like AA:BB:CC:DD:EE:FF.
If nothing else works, factory reset the Roku. Go to Settings > System > Advanced system settings > Factory reset. After the reset, set up the network connection fresh. This clears all settings including any corrupted network data.

A factory reset will remove all your streaming apps and settings. You will need to sign back into your Roku account and reinstall your apps, but it is a reliable last resort.

When to Call a Professional

If you have correctly entered the Wi-Fi password and still get error 056, check your router's admin settings. A network administrator or your ISP can help you verify MAC address filtering, DHCP settings, and wireless security protocol compatibility. For Roku TVs that still fail after a factory reset, contact Roku support at support.roku.com — they can help diagnose hardware-level network faults.

Frequently Asked Questions

Why does Roku reject my correct password?

Sometimes the issue is not the password itself but the security protocol. If your router recently updated its firmware and switched to WPA3, and your Roku model only supports WPA2, the Roku will fail authentication even with the right password. Try logging in to your router's settings and checking whether you can set it to use WPA2/WPA3 mixed mode to support older devices.

What is MAC address filtering and should I use it?

MAC address filtering is a router security feature that only allows specific devices — identified by their unique MAC address — to connect to your network. It provides a small extra layer of security, but it is not very effective against determined attackers. More importantly, it means every new device you connect needs to be manually added to the allowed list. If you are not technically confident, turning it off is simpler and still leaves WPA2/WPA3 encryption protecting your network.

Will a Roku factory reset delete my purchased content?

No. All your purchased movies and apps are tied to your Roku account, not the device itself. After a factory reset, sign back in to your Roku account and all your purchases and subscriptions will be restored. The reset only clears local settings on the device — nothing stored on Roku's servers is affected.
