Placing the Wi-Fi transmitter next to some devices and household items can slow down the network speed due to interference or frequency conflicts. Usually, users often place modems, Wi-Fi routers in the center of the house or convenient location to connect with many family members. However, being close to some other objects can cause the signal to be blocked, thereby slowing down the Internet connection. **TV, refrigerator** According to Eye Networks, placing a Wi-Fi transmitter next to the TV is quite common in many households, especially rooms with a small area. However, when the TV is in operation, the magnetic field waves will emit a strong frequency that causes most modems or routers to be interfered with, and the Wi-Fi waves emitted are unstable. Similarly, placing the transmitter next to refrigerators, washing machines and other devices that emit magnetic fields when operating also causes network waves to flicker. **Glass cabinet, mirror** Some users put the Wi-Fi transmitter in front of the mirror, but experts say this is not advisable. According to *CNBC*, placing near objects such as mirrors or similar silver-plated objects causes Wi-Fi waves to be reflected instead of through, and creates interference, causing devices behind to receive the signal. least. Similarly, glasses have a negative impact on Wi-Fi waves because they are both an obstacle and a signal, so users should not put the Wi-Fi transmitter in a glass cabinet. **Aquarium** Water has the ability to partially absorb radio waves like Wi-Fi, so a transmitter next to an aquarium or water tank may make the signal weaker than in other locations. In addition, this area has high humidity – the “enemy” of electronic devices. **Microwaves** Most Wi-Fi transmitters currently use the Wi-Fi 6 standard (frequency 2.4 GHz – 5 GHz), or the newer Wi-Fi 6E (6 GHz frequency). Because microwave ovens use 2.4 GHz electromagnetic waves to heat food with high frequency, they can cause interference with older Wi-Fi transmitters. In addition to microwave ovens, devices such as walkie-talkies and radios can also cause interference because they also operate on the 2.4 GHz band. With devices using the new Wi-Fi technology, the impact of the microwave is lower. **Bluetooth devices** Bluetooth wireless devices such as headsets, keyboards, and mice can interfere with Wi-Fi signals, especially older 2.4 GHz transmitters. According to *MetaGeek*, when a Bluetooth device jumps into the band of a Wi-Fi device, it interferes with it and causes latency. Wi-Fi transmitters can also interfere with the operation of wireless mice and other Bluetooth accessories.
