# Does the use of devices such as power bars and surge protectors interfere with my wifi?


# Power bars and surge protectors are an excellent way to safeguard your electronics, but are there any drawbacks?
*Yes, unfortunately, there are negatives to all products such as smart plugs, power bars, outlet splitters, and surge protectors.*

###### Let's discuss about electromagnetic interference!
 Electromagnetic interference/radio frequency interference ( **EMI**) is unwanted noise or interference delivered into an electrical route or circuit by an outside source. EMI can cause devices to underperform, malfunction, or fail entirely.

### What impact does electromagnetic interference have on your network?

Wi-Fi uses a **radio frequency** comparable to AM/FM radio to wirelessly **transmit data across long distances**. Due to all of the shared frequencies, it is difficult for the router to broadcast a strong signal when devices in the same region and use the same frequencies.

###### ${color}[#5189b3](What exactly is the connection between these devices and electromagnetic interference?)

**Electromagnetic interference ** may be generated by any power supply, including **smart plugs, power bars, outlet splitters, and surge protectors and extension cords.** These devices can produce a electrical noise that can cause the modem to **operate poorly, malfunction, or completely fail.**

### ${color}[#5189b3]( Lifespan)

Many people are not aware of this. The metal that disperse excess heat begin to deteriorate after a few years, which causes the **devices like surge protector and power bars to lose its efficiency**.

||| **These adapters have a lifespan of three to five years.**

* Due to the deterioration of the adapters, these products may produce too much **electrical noise as a result of surges or reductions** in power.

| Devices such as power bars, surge protectors, power bars, smart plugs and extension cables should be replaced every few years because the materials could degrade over time.

* Please also note that **inconsistent power delivery** in **defective power bars, surge protectors, power bars, wall splitters, and even defective wall sockets** can create issues for sensitive networking equipment such as modems and routers.
