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

The App is Great. I have a few suggestions, though. 1. Provide the ability to name connected devices so that blocking them can be easier. 2. Make download and upload speed indicators MB/s, not Mbps, so that tracking speed is more easily understood. 3. Ability to cap data limit on a particular connected device. So that, that particular connected device does not use data more than necessary.

Loads of issues so far, the biggest one being that even when you have set a preference for which node you want another node to connect to, it only takes a node dropping (which they do regularly) for it to completely reorder the network and ignore your set preferences for connections. You can't manually change the network layout with ease and when it resets it, it's a pain to restore it to your original layout.
