Several things to check....

• Be sure you are using a good Ethernet cable. I have seen reported that even a new cable failed.
• Power off the modem, router and PC. Bring them up one at a time waiting for each to stabilize. Modem, then router, then PC.
• Are you getting a WAN IP address? if not see https://community.tp-link.com/us/home/forum/topic/150603
• If that does not help, let us know the name of the ISP as others may be able to help with specific WAN settings.

Thank you very much for that advice.

Some things i already attempted - while others I will as soon as i can.

One thing i can say for sure is the cable not faulty as i attempted to use the cable from previous router aside of the new one. 

I also ensured all the LED's on my modem indicate its ability to connect before plugging the modem and then after the modem indicates its status (all LED's green aside of the internet which is amber) i plug a fully booted PC with drivers installed and updated. My pc can see the LAN but don't get internet access. I will check the WAN IP it attempts to get after looking at how to do it since using ifconfig on my machine only returns the LAN parameters (or im using it wrong) - im fairly new to linux so kit will take a bit of research.

P.S.

My ISP is a polish company operating in Krakow (maybe somewhere else i don't really know) - it's called Sebit.
