Why WiFi Is Worse in Apartment Buildings
WiFi in flats and apartment buildings is often slower and less reliable than expected.
This is usually due to:
- Interference from dozens of neighbouring networks
- Thick walls blocking signal
- Router placement issues
- Overloaded networks during peak hours
👉 Even fast broadband can feel slow in these conditions.
According to Ofcom, WiFi performance in dense housing is heavily affected by interference from nearby networks.

5. Try a WiFi Extender or Powerline Adapter
If only one room has poor signal:
- Extenders boost wireless signal
- Powerline adapters use your electrical wiring
👉 Great for targeted fixes.
6. Reduce Device Congestion
Too many devices can slow everything down.
- Disconnect unused devices
- Limit background downloads
- Upgrade router if needed
👉 Modern homes demand stronger routers.
7. Position Your Router Away from Obstacles
Avoid placing your router near:
- TVs
- Metal objects
- Thick walls
- Cupboards
👉 Clear space = stronger signal.
