A 120 - sq - m home with numerous smart devices faced network problems. Installing a 1200M AC router with 2T2R MIMO solved them. It auto - optimized, switched bands. 4K playback, online study and smart speaker performance all improved.
(I) Home Network Requirements and Problems
Mr. Li's family lives in a three-bedroom apartment with an area of 120 square meters. There are numerous smart devices in the house, including a smart TV, smart speakers, multiple smartphones, tablets, and a laptop used by the children for online learning. As the family members' dependence on the network increases, the original network equipment fails to meet the demands. Problems such as insufficient signal coverage and slow network speed have emerged. Especially in the evenings when the whole family uses the network simultaneously, the lagging phenomenon is particularly severe.
(II) Selection and Installation of the 1200M AC Wireless Router
To solve the home network problems, Mr. Li purchased a 1200M AC wireless router. This router adopts the advanced 2T2R MIMO antenna technology, which significantly enhances the signal strength and coverage range. During the installation, Mr. Li placed the router on the TV cabinet in the living room to ensure that the signal can evenly cover all rooms. After a simple setup through the mobile phone APP, the router automatically optimized the network configuration and achieved intelligent switching between the two frequency bands, automatically selecting the most suitable frequency band for connection according to the usage scenarios and distances of the devices.

(III) Improvement of the Home Network Experience
Since replacing the router with the new one, the network experience of Mr. Li's family has undergone a qualitative leap. The smart TV plays 4K high-definition videos smoothly without any interruptions, and the pictures are clear and vivid, allowing the whole family to fully enjoy the fun of large-screen movie watching. When the children are learning online, the video courses play stably, and the interactive quizzes can also be responded to quickly, ensuring the learning effect. The voice control of the smart speakers has become more sensitive, and it can play the music that the family wants to listen to and query various information at any time. Mr. Li said with a smile, "Now the home network is like a whole new world. Every family member can use the network smoothly, and the smart home devices are truly bringing their advantages into full play."
