    Why is the DHCP client checking for WAN DHCP server in every 150 seconds? Fact that DHCP server on ISP's side is "blocking me out" in every 2h made me investigate the issue.
    Then only changing the MAC helps me to bring back the Internet…

    Is there a way somewhere (even if by CLI) for increasing the renewal period?

    Ask your ISP. It is the DHCP server that assigns the DHCP lease time.

    This. If you're renewing every 150 seconds, you're getting a 300 second lease. Our dhclient follows the RFC the same as every DHCP client, renewing at half the lease length.
