@David-TP Hi David, thanks for your reply. Unfortunately the setup was made few years ago and i doubt even if i contacted my ISP, they are unable to help. I guess the best way is to reset my router...

I have never login to my X60 router using deco app and the setup was done by the ISP. When i want to login to my x60 router using deco app, it prompts me to setup my x60 router which i need to reset...
