5G coverage: The coverage of 5G networks may be relatively narrow, especially in the initial deployment phase. Before buying a 5G router, be sure to understand the 5G network coverage in your area or consult the operator's information to ensure that you can get 5G signal coverage, and know in advance whether additional antennas or equipment are needed to enhance the signal.

Network package: Using 5G will consume more data traffic, so before choosing a high-speed 5G router, you need to ensure that you have an appropriate 5G network package to avoid exceeding your budget or encountering additional fees. Contact the operator to learn about the 5G package that suits your needs, and make sure that the router is compatible with the selected package type.

Router Compatibility: Make sure the purchased 5G WiFi6 router is compatible with your device. Different 5G routers may have different network frequency bands, interfaces and protocol support, so before buying, make sure it can seamlessly connect with your devices (such as computers, mobile phones, smart home devices, etc.).

Security: Like other routers, it's important to keep your 5G router secure. Make sure to protect your wireless network with a strong password, and regularly update and maintain your router's firmware. Also, disable unnecessary ports and features, and enable network firewalls and encryption to improve network security.

Router placement: Make sure that the 5G router is placed in a location with good signal coverage and close to the devices that need to be connected. Try to avoid signal interference from obstacles (such as walls, large furniture, etc.) to ensure the best 5G connection speed and stability.

Number of devices and bandwidth requirements: If you have multiple devices that need to connect to the 5G router, make sure the router has enough bandwidth and processing power to support your needs. If the network load is heavy, it may affect the connection speed and stability.
