Short answer: Check the phone and target on the intended local network, then review permissions and discovery before reinstalling the app.

Confirm the target no longer uses the retired network. A router replacement can leave the phone online while the television still remembers an old network. Compare the current connection on both devices before reinstalling a remote app. Keep a working physical control available to change TV settings and approve a new connection. This situation rewards a short written checklist: old network, new network, target device, and the first action that fails.

Wi-Fi for Remote Apps for After a Router Change
Start from the equipment in this room. A Wi-Fi tips guide should distinguish signal strength from visibility. A strong internet connection can coexist with isolation between local devices. Check the actual network and the product-specific permission requirements, then test discovery again. Do not change unfamiliar router settings in bulk; keep the original configuration recorded and preserve a working way into television settings.

Keep Network Checks Specific to the Product
Confirm that networking is involved
First checkpoint: Find out whether the control method uses infrared, a paired radio connection, or a phone app on the local network. Apply Wi-Fi advice only to the portion that depends on it. Internet streaming and remote response are not identical tests.

Test visibility before reinstalling
Second checkpoint: For an app route, compare the target connection and phone access, then retry discovery. Follow the product instructions for any setup restrictions. Preserve a physical way into settings while investigating so a failed network change does not remove your remaining control.

Build a Local Connection That Devices Can Use
Connect the phone and television to your home network before scanning. Guest networks and router isolation can let both devices reach the internet while preventing them from discovering each other. Internet access and local communication are separate checks. A wired TV can work with a wireless phone when both connections lead to the same local network. Different Wi-Fi bands are not automatically a problem, although a particular app or setup procedure may impose a narrower requirement. Check that requirement before changing router settings.

Use Manual Connection Only When Supported
Some versions of the official Roku app offer a manual connection option. If yours does, obtain the current Roku IP address from the device's network information and enter it exactly. An IP address is not a substitute for network reachability. Manual entry cannot cross router isolation or connect a device that is offline. Check the address again after a router restart because it may have changed. Do not copy an example address from a tutorial or assume the last number should match your phone.

Check the Home Network Before Reinstalling
Internet access alone does not prove device visibility
Internet access alone does not prove device visibility. Put the iPhone and target on the intended home network and check whether a guest network isolates clients. A television connected by Ethernet may still be on the same local network as a phone on Wi-Fi.

Check the result on your equipment
Different radio bands do not automatically mean different networks, although a product's setup instructions may impose specific requirements. Temporarily review VPN or filtering behavior when diagnosing discovery. Change one setting at a time and restore any diagnostic change after the test.

Give Device Discovery the Required Permission
When an app requests access to devices on your local network, denying the request can leave an otherwise compatible television invisible. Review the app's permissions in your phone settings, then reopen its device list. Android permission labels depend on the OS and discovery method; follow the app's documented explanation. Grant relevant discovery access rather than unrelated permissions. A VPN may also change how local traffic is routed. If you temporarily disconnect it for a test, restore your preferred configuration after establishing whether it affected discovery.

Recover After a Router or Password Change
An old pairing cannot repair a missing network connection
A saved device entry does not reconnect a television to a new network by itself. After changing the Wi-Fi name or password, use a supported controller to join the television to the replacement network.

Check the result on your equipment
Then connect the phone and scan again. An old pairing cannot repair a missing network connection. Save the TV model and the app name before making household network changes. Keeping a compatible physical remote available avoids a recovery loop in which the app needs a network connection that only the TV menus can establish.

Compare the Phone and Roku Network Connections
Open the phone's Wi-Fi settings and compare its connection with the network used by the Roku. A guest network, an extender configured as a separate router, or a second household router can split devices that appear to share an internet connection. Both devices need a usable local path to each other. Roku's official mobile-app instructions call for the same Wi-Fi network. If your Roku model uses Ethernet, verify the router arrangement against its model-specific guidance instead of assuming any wired connection is automatically equivalent.

Keep a Practical Household Backup
Phone control works best when everyone knows how to choose the right TV and recover from a lost connection. Keep basic written instructions with the physical remote: turn on the TV, connect to the household network, select the saved device, and test navigation. Keep recovery access outside the app. A discharged phone, a changed permission, or a router outage should not leave the household unable to reach the television's settings. Maintain the original remote or a verified compatible replacement for setup and exceptional situations.

Final Thoughts
Check the phone and target on the intended local network, then review permissions and discovery before reinstalling the app. Keep the successful setup documented. Save the correct target, essential commands, and recovery method. Recheck the routine after equipment or software changes, and investigate the first failed stage while preserving any controls that still work.
