mridhulofficial Posted September 19, 2020 Share Posted September 19, 2020 (edited) Hi team, Please advice me for the issue. Already gone through other posts. My spec Ryzen 9 3900x and Gigabyte B550 Aorus Pro AC motherboard. I installed Cataliana on my system .. everything looking perfect exept ethernet. Installed LucyRTL8125Ethernet.kext and ethernet is showing on network window but no internet connection. Adjusted hardware settings in network as Manually/100baseTX/full-duplex, flow-control but issue not fixed. Please help me. Thanks is advance.

miliuco Posted September 19, 2020 Share Posted September 19, 2020 (edited) It's Realtek RTL8125 family Ethernet? There are comments from other users that with RTL8125 and LucyRTL8125Ethernet can see the adapter in System Profile without being able to connect to the Internet. The author of this kext (Giant Cat) recommends in these cases to try configuring in System Preferences> Network> Advanced> Hardware manually instead of automatically. Try to see if that way works well. See here. Edited September 19, 2020 by miliuco Link to comment Share on other sites More sharing options...
