Welcome to the Raspberry Pi forums.
before i could use internet
Before what? What have you changed recently?

Have you somehow installed an older version of Raspbian on your new RPI3B+ ?

(Not something you can do by accident.)

The name of the Ethernet interface is a result of the Predictable Interface Names option being enabled. It is only a problem if you have some customisation that relies on the alternative non-Predictable naming.

As an experiment to check the hardware of your RPi, try writing a fresh download of Raspbian Stretch to a spare microSD card and boot from that.

Me too using raspberry pi 3, b+. Though I'm connected to the network but not able to access the internet. I've checked the router and it's working properly. Also, I'm using VPN to harden my security. Can VPN be the reason of the problem? I'm trying to access sites listed here: https://watchseriesonline.live/
