Roku Remote Not Finding TV? Here is the Checklist.

You opened the app, you clicked rescan, but the list is empty. It is frustrating, but don't worry—99% of discovery issues are caused by simple network settings rather than a broken app or TV.

Follow these 5 steps to get connected in minutes.

1. Check the "Network Profile" in Windows

Windows has two main network profiles: Public and Private. By default, Windows blocks local discovery on "Public" networks for security.

Go to your WiFi settings on your PC and ensure your home network is set to Private. This allows the app to communicate with other devices in your house.

2. Enable "Control by Mobile Apps" on Roku

Your Roku has a security setting that can block all remote apps. Grab your physical remote (or use the TV buttons) and go to:

Settings > System > Advanced system settings > Control by mobile apps > Network access

Ensure this is set to Default or Permissive. If it is set to "Disabled," no app will ever find your TV.

3. The "Same Network" Rule

Many modern routers provide two frequencies: 2.4GHz and 5GHz. Sometimes they act as separate networks. Ensure both your Roku and your PC are on the exact same WiFi name (SSID). Also, avoid Guest Networks, as they explicitly block devices from "seeing" each other.

4. Disable VPN or Firewall Temporarily

Corporate VPNs often "tunnel" all traffic, making your PC think it is at the office instead of in your living room. If you are using a VPN, disconnect it and try scanning again. Likewise, if you have a third-party Firewall (like Norton or McAfee), ensure it isn't blocking UDP port 1900.

5. The Classic "Power Cycle"

If all else fails, unplug your Roku from the wall, wait 10 seconds, and plug it back in. This forces the Roku's network card to restart and re-broadcast its presence to the network.
