How to Improve Android WiFi Signal Strength?

Try a simple 5 GHz test.

  1. On your router, enable 5 GHz WiFi and give it a different name, like “HomeWiFi_5G”.
  2. On your Android, forget the old 2.4 GHz network.
  3. Connect only to “HomeWiFi_5G”.
  4. Stay in the same room as the router when you work.

5 GHz often gives higher real speeds and less interference from neighbors.
If things improve in that room, you know distance and walls hurt your signal, so you keep work closer to the router.
