Quick answer
Dead zones should be mapped before buying equipment. Room layout, wall type, device band, router position and interference can all point to different fixes.
What to check
- Map where signal drops, slows or becomes unreliable.
- Note whether the issue is distance, a particular wall or a specific device.
- Test 2.4GHz and 5GHz behaviour if the router separates them.
- Check whether the router is hidden, low down or near interference.
- Compare extender, mesh and cable options after diagnosis.
Trade-offs
An extender can help one location but may reduce throughput. Mesh can improve coverage but needs good node placement. Ethernet backhaul is stronger where cabling is practical.
Before you buy
Check current manufacturer specifications, router or laptop compatibility notes, warranty and return terms before ordering. This guide does not provide live pricing, service guarantees, installation advice or first-hand test claims.
