Hi TPLINK team,
I detected suspected devices(hostnames) which are in my omada controller oc 200. these devices used my wifi for more than days already. my wifi voucher code is only for 1 hour
but such devices used more than 1 hour. Currently I have blocked them. My question is there any possibility that my oc 200 is hacked? Please see attached file of screenshot of the usages and for your assistance please.
Thanks!
Hey
This is quite common if you are using voucher codes with an open network. One of my neighbours devices has been connected on and off for months as they seem to have set it as a saved network on their phones, however they have never authenticated / been given a voucher so basically they are just sat at the voucher / portal page for months 
Likely the same in your case
If you check data traffic, likely very low (MBs) at most as they will have just downloaded/refreshed the portal hundreds of times over but not actually been authorised
The act of connecting to the WiFi and hitting the portal will register them on the OC200, but not actually allow them anything unless they redeem a code
