原裝小米WiFi路由器4A智能APP控制AC1200 1167Mbps 128MB 2.4GHz & 5GHz雙核CPU千兆以太網口無線路由器中繼器，配備4根天線，支持網頁及Android和iOS，美規插頭，4A（雙核CPU）

1. Provide one Gigabit WAN port and two Gigabit LAN ports, which can easily meet the access requirements of fiber optic broadband of 100M and above. Compared with the router of 100M network port, it can fully utilize the carrier per megabit bandwidth.
2. Equipped with dual-core four-thread processor, the single-core frequency is up to 880MHz, and the powerful performance easily supports data forwarding of Gigabit Ethernet port and Gigabit dual-band Wi-Fi, and the Internet experience is smoother.
3. Provides two frequency bands of 2.4 GHz and 5 GHz without interference, and the dual-band concurrent wireless connection rate can reach up to 1167 Mbps. The 2.4GHz band transmits farther, has better coverage, and better wall penetration performance. The 5GHz band uses 802.11ac technology with less interference and high speed. It is more smooth to watch high-definition video and play large online games.
4. Dual-frequency, a WiFi name, no longer tangled. The optimal frequency band is selected autonomously by the dual frequency terminal.
5. 4 external omnidirectional high-gain antennas, good signal through the wall.
6. The PA and LNA are integrated inside the 2.4 GHz and 5 GHz wireless chips. The signal transmission distance is farther, the wall is better, and the coverage is wider.
7. In the era of smart homes, more devices need to be networked. With 128MB of large memory, it can stably connect 128 terminal devices.
8. Optimize the connection for Xiaomi smart home equipment, that is, after the router changes the password, there is no need to set up the smart home equipment one by one.
9. IPv6 has a larger address space, making the Internet of Everything possible.
10. Intelligent error correction algorithm to improve weak signals and make transmission more stable and efficient.
11. Others pay for the Internet and exchange free bandwidth for revenue to help you make money. The host and guest networks are isolated to ensure security.
12. Effectively protect your family health by setting the device networkable time and the range of URLs allowed to access. Combined with the intelligent speed limit function, you can limit the Internet access speed of each access device to avoid network congestion caused by individual devices.
13. Someone slams the net, notifies the phone in real time, and pulls the button black. Internet settings are quick and easy, and are easy for parents to use.
14. Xiaomi WiFi APP contains a variety of practical functions such as one-button speed measurement, Wi-Fi optimization, and anti-smashing network. It can easily manage routers and their access devices, and remotely control them anytime, anywhere.
15. The fuselage adopts large-area aluminum-magnesium alloy heat sink and high thermal conductivity thermal conductive glue. The bottom of the hole is opened in a large area, which is super heat-dissipating to ensure stable operation.
