what would be the best connection for me?

[ImNotASheep]

My first custom PC is currently placed in my room while my router is placed in the kitchen (only ADSL outlet in the house). The problem is that I have a thick concrete floor between the 2 and was wondering which connection I should use. I was thinking about a powerline Ethernet adapter? Do you have any suggestions, I'd really like to keep the PC in my room but if the connection is too bad I'll have to move it elsewhere...

Should get a Cat 6a ethernet cable and plug it in your pc

Powerline is likely your only realistic option. If you have tv coax you could consider MoCA.
