Compare locations
Testing the same device closer to the router helps distinguish coverage from device performance.
Notice physical obstacles
Dense walls, floors and metal structures can weaken radio signals.
Avoid promising one perfect router location
Home layouts differ, and mesh or additional access points may be appropriate in some larger spaces.
Do not confuse speed with reliability
A connection can test fast near the router yet still be inconsistent in a distant room.
