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.

I nearly spent £200+ on a 4g Router, but accidentally bought this one. I cannot believe the performance of this little gem. Normal 4g signal is 54bps, but this router puts out 78bps. Absolutely amazing!

MR50G user. The app is clean and easy to navigate, but there's a bug with the Guest Network, it shows "0 Online" even with devices connected. I have family on my guest Wi-Fi and the count stays at zero. Main network shows clients correctly (2 Online), so it's clearly a Guest Network issue. Accurate client monitoring is essential for a router app. Please fix this in the next update.
