In some situations you may find the Wi-Fi signal is better in different parts of the room. This can dramatically affect the radio signals between your router and Wi-Fi device, and can cause slow or intermittent connection problems. Generally walls like this are made of more substantial material brick, stone or concrete.
However, for the laptop in the kitchen, the signal has to penetrate a load bearing wall - so, despite being closer, the signal is weaker. The laptop in the loft conversion is much further away this weakens the signal slightly and some performance issues may be experienced. The laptop directly above it in the bedroom has full signal strength, as generally the signal can penetrate through ceilings without any problems.
The image above shows the router connected to the phone line in the living room. This will either cause noise or a complete dropout of the station you are listening to. If you are driving in a multi-storey car park, or driving through a tunnel, the signal to your radio will weaken. These are suspectible to intereference, much in the same way as the radio in your car. The following diagrams will show the effect on the wireless signal to devices using your Wi-Fi network in different situations.Įven though the data transmitted over Wi-Fi is digital, the actual signal uses analogue radio waves. Internal walls:The biggests factors which reduce Wi-Fi performance are the effect distance and internal walls have on signal strength.
