[TL-MR100] Abnormal data transfer in 3G/4G router
Hello,
I'm facing an issue related to TL-MR100 routers that are transferring an abnormal high volume no sense data.
I have a live experiment test. A router is actually serving 2 IoT devices that consume about 60KB/day data transfer, so it's a total 120KB/day. The problem is the router is counting an average daily transfer of 10MB. Even the mobile service provider (Things Mobile) is confirming those 10MB/day. This situation carries unnecessary data transfer fees that block this project sales launch.
I have to say, the router is secured using WPA2 secure password and only those two IoT WiFi clients are actually connected. I have also tried alternative SIM cards/providers with similar results.
What can be producing such amount of hidden traffic?
How to prevent/block that traffic?
Is anyone of you using this kind of mobile routers for IoT connectivity and facing the same issues? Any workaround ideas?
Thanks for reading!
