Does it replace my existing router?

No. It's a repeater: it doesn't create a network from scratch, it picks up your router's signal and rebroadcasts it further to extend Wi-Fi range. You still need a router providing the internet.

What speed and band does it offer?

It runs on the 2.4 GHz band (Wi-Fi 4, 802.11b/g/n) at up to 300 Mbps. There is no 5 GHz band. 2.4 GHz passes through walls better, so it's suited to coverage rather than gigabit speeds.

Does it have an Ethernet (LAN) port?

No, it's a wireless-only model. There are no Ethernet ports, so you can't connect a device to it by cable — all connections go over Wi-Fi.

How is it set up and which app do I need?

Setup takes a couple of minutes via an app. Use Xiaomi Home if you don't have a Xiaomi router, or Mi WiFi if you already own one. The app walks you through connecting the repeater to your network.

How many devices can I connect?

The repeater serves up to 16 devices at once — phones, TVs, IP cameras, and Wi-Fi smart-home devices.

What warranty and delivery do you offer in Moldova?

The product comes with 24 months of official warranty. CasaSmart delivers in Chisinau and across Moldova.
