What Should I Do If Coverage Varies Between Rooms or Floors?

If you notice inconsistent coverage, repeat tests in multiple rooms and at different times to capture typical usage, using the same device for consistency. Test with both a SIM mobile signal and any fixed broadband option you’re considering to compare results, and ask the provider where fibre terminates in the unit, who owns the internal cabling, and whether there is a dedicated line for your space or shared access through a building distribution point. If results still vary, document the exact locations (rooms, terraces) and the test dates. For weak work areas, check router placement and power reliability, and explore practical fixes like a central router, a booster, or a mesh network, while confirming whether the building management allows any upgrade or service improvement. Consider a professional site survey or independent telecom assessment as part of due diligence, and ensure basic electrical, water and network systems are sound first. Do not rely on maps or neighbours’ service alone. Having written evidence and professional advice helps you choose a solution that works where you actually live and work.
