Thanks, Kathy.

As you said I could see the default IP address on the static option, I tried them too, still, shows Ethernet connected but the internet doesn't work.

As per my knowledge, I have not seen any driver in my Mi box as it's directly showing Ethernet connected as soon I connect the LAN cable from Modem. But the internet doesn't work.

However, the same adapter works fine when trying with a laptop without any problem.
