Your PC will be using IPv4 to connect to the router, don't worry about IPv6.
You are finding the DHCP server and being allocated an IP of 192.168.1.2.
I would check to see the router is actually connected to the internet.

The router IS connected the internet, checked through:
1. Laptop
2. Phone

Also I changed the LAN cable, in case the cable prior was faulty, with same result.

And also, might this assist with the troubleshooting?:

 

[Skyferia]

I found the root cause, and it's very silly!
What happened was that the LAN/Ethernet cable was connected to the modem, not the router.

When called the ISP customer service:
1st Representative (8th June): Asked to connect the phone line to the TEL1 port, disregarding the DSL port
2nd Representative (8th June): Asked to connect the LAN/Ethernet cable from modem to computer*
3rd Representative (today, 10th June): Said connecting to modem is incorrect, should be connected to the router -> connect to router -> issue resolved

Thanks for the help VincentP, this thread can be closed.
