Dead ethernet ports after changing routter

Hi everyone.

I was instaling a sonoma instalation on a friend PC, everything working perfectly fine on my house, but after changing to my friend routter, The 2 ethernet ports stopped working, even o Windows 11, ports dont show any sign of life. Is this a hardware problem or Just a Config issues?

The kexts that I use for ethernet:

LucyRTL8125Ethernet.kext RealtekRTL8111.kext

Config. Cpu i5 12600f Mbo erying b660 32gb ram Rx 6600 Bcm 94360ng
