Hey @Dariush55 ,
Please try to re-login your credentials on the TPG application and perform a reboot at the modem/router. By doing this the TPG App log-in will re-sync the status of the service.
Let me know how it will go.
Why every single time I check my connection status in the app it says your internet service is offline while my internet is working and even the speed test shows very good speed? Is something wrong with the TPG app?
