One of the most frequent questions we get from customers is: "How can I extend the range of my WiFi network cost-effectively and without the hassle of laying cables?" Especially in multi-story houses or large apartments, a single router quickly reaches its physical limits.
The most straightforward solution is using a WiFi Repeater (also known as an extender or booster). It acts as a digital relay station: it picks up the fading signal from your router, processes it, and rebroadcasts it with fresh power.
Practical Example: WiFi Across Three Floors
- Ground Floor: This is where your router is located. Reception is perfect.
- 1st Floor: The signal still penetrates the ceiling well; streaming works without issues.
- 2nd Floor: The signal is barely present. The connection drops constantly.
The most common mistake: Many people plug the repeater into an outlet on the 2nd floor, where the signal is already poor. However, a repeater can only amplify what it receives!
The Golden Rule of Placement
For optimal results, place the repeater exactly halfway between the router and the dead zone. In our example, the ideal hiding spot would be the 1st floor.
FAQ: WiFi Repeaters
Where is the best place to put my WiFi repeater?
The best location is halfway between your router and the dead zone.
Does a repeater halve my internet speed?
This was true for very old single-band repeaters. Modern dual-band repeaters bypass this problem by receiving on one frequency and transmitting on another.
