>> Wi-Fi is distinguished into 2.4GHz and 5GHz, 2.4GHz signal transmission distance is farther than 5GHz, but slower than 5GHz, 5GHz although the signal transmission distance is shorter, but the speed can be faster.
When your wireless device is often disconnected, you can first check that your wireless device is connected to Wi-Fi (2.4GHz or 5GHz) and confirm the distance between the wireless device and the router when the Wi-Fi is disconnected.
Interferences: microwave ovens, refrigerator, wireless phones, power boxes... And so on, some home appliances will also produce interference with wireless channels.
Barriers: iron cabinets, iron doors, cement walls, closed cabinets, placed on the ground, behind the sofa. Some high-density building materials can also affect Wi-Fi signal penetration, such as gypsum, planks, barbed wire, etc.
>> It is recommended that you place the router in the center of the environment where possible, in an open area, where there is less furniture, where there is no wall barrier, or on a wooden cabinet, on a tabletop.
- Wireless device: Such as Laptop, Smart Phone, USB Wi-Fi Adapter, CONSOLE.
Note: Mac device Wi-Fi signal is often disconnected after roaming between AiMesh router and nodes, refer to this FAQ.
9. Restore the router to default settings.
Following pictures take RT-AC68U as an example.
