About this app

Currently supports all Halo Mesh devices and some compatible routers (such as MR70X and MR30G). With MERCUSYS, you can monitor your home Wi-Fi from anywhere, and make changes right from your smartphone or tablet.


With Mercusys Mesh Technology, a set of three Halo units covers most homes (up to3000 square feet). The units work together to create fast, reliable and seamless Wi-Fi. At last, you can stream, game and browse in any room-even your basement or attic!


MERCUSYS features:
- Easy setup
- Parental controls
- QoS
- Guest network
- Monthly reporting
- Remote network management


To set up your Halo network, simply plug one of your Halo units into your modem and follow the instructions in the MERCUSYS app. The app also helps you find the best spots in your home to place additional Halo units.


Once your Halo network is up and running, you can enjoy faster, stronger Wi-Fi connections that won't drop out, even when you're moving from room to room.


Plus, you can manage your entire Halo Whole Home Mesh Wi-Fi System right from the MERCUSYS app,including:
- Sharing your guest network with visitors
- Viewing which devices are connected to your Wi-Fi
- Restricting access to websites of your choosing
- Setting a time restriction and pause the Wi-Fi on kids' devices
- Controlling when certain devices have Wi-Fi access
- Picking which devices get Wi-Fi priority
- Adding a family member as a network manager to help you monitor your network

⭐ Poor App Performance & Cloud Connectivity – Mercusys MR80X ⚠️ 📱 App Performance: The Mercusys app is very slow and often fails to open or connect properly. ☁️ Cloud Performance: Remote access over the internet frequently fails or takes too long to connect. 📶 Local Wi-Fi Access: Even when connected to my own router's Wi-Fi, the app is slow and unresponsive. ⚡ My Request: Please improve app performance, cloud connectivity, remote access, and router management reliability through software a

Not enough icons inside the device list there aren't enough IoT icons, TV, gaming console is missing, it takes some time to refresh the device list on an android 16 device, intermittent loss of device availability on either of the nodes, they suddenly show Zero count inside the App.
