A shared boundary
A router handles traffic for phones, laptops, cameras, and smart devices. Unfixed firmware flaws can affect the whole network.
Identify hardware and firmware
Match model, hardware revision, region, and firmware train. Similar retail names can use different update files.
Plan replacement
Check official firmware and end-of-life notices. When fixes stop, replace the router and update admin and Wi-Fi credentials.
