I already have a solution regarding anti tehering. I use Mikrotik Hex and er605, oc200 and a gigabit switch with mikrotik config. We managed to eliminate tethering in omada

  @TAKS if mikrotik can do it, omada should but we have to wait for the update.

my problem with using hex is that it will hangup when used with higher telco connection reason why i'm now using er605. tethering/hotspot is the only problem as omada routers are blind to the hotspot connections of a connected device. 

  @Virgo Yes, They can Connect using Hotspot Phone in other HighEnd Phone, and especially  Brand new Phones. 

  @TAKS Its very hassle for small business. and you need spend for MTK 

  @Set-up Why can't OMADA do this anti tethering setting is mikrotik better than OMADA? 

  @Sh0ckWaVeZzz reason why people choose mikrotik is the anti tethering many is learning to config mikrotik and considering to transfer to it. I migth do it as well soon. tried it already and it is working well a little bit of learning but once you done it, it will be easy the next time.
