Wireless debugging is convenient until the pairing port rotates, the phone sleeps, or your laptop quietly joins the guest SSID. Most “it worked yesterday” wireless ADB stories trace back to a small set of network and power state mistakes—not a broken mirroring app.
If mirroring fails at the connection step, the root cause is often one of a handful of ADB-adjacent issues. This post collects the fastest checks we see in the wild.
NearMirror supports USB and wireless connections. Both can work well; the right choice depends on your desk layout, router, and how sensitive you are to latency.
Most desktop Android mirroring tools—including NearMirror—lean on ADB (Android Debug Bridge) under the hood. You do not need to memorize commands to use mirroring day to day, but understanding ADB helps when something fails to connect or when you read logs and docs.
