<< Solved >> Network stop working after rebooting on Catalina

[Philipe-abner]

Hi guys!

I’ve just installed a fresh build of Catalina but it is 10.15.1.

Initially I was getting no sound but my network was working great. After fixing my sound, I had issues with my network.

After rebooting the system, the internet connection was gone. I decided to reinstalled the system, and got it all working, Audio and Network.

Although, after two or three days workings fine, when I turn the computer on today the network was gone again.

System
I5 3570k OC 4Ghz
Asrock Z77 Extreme 6
Network: Broadcom BCM57781
Using HD4000
12GB Ram
SSD 240GB formatted APFS+
Smbios: iMac 13,2

Kexts that I was used to install for network on Captain and High Sierra was IONetworkingFamily.

Observation: I’m a noob, I don’t know how to patch or create custom things, if you guys could explain, I would appreciate it.

Hi guys, I've solved the problem, and I'm gonna tell how:

I decided to reinstall the system (fresh installation). So I did and as soon as I installed all the kexts and got the audio and network working again, I decided to find out the informations of my Network Card (which is Broadcom). I screenshot it and after I reboot the systems a couple of times, my internet connection was gone again.

With the Network card's information, I tried to insert a fakeID. So I opened Clover and entered the ID of my network card, which is 0x16B1 for Broadcom 57765-B0 and now it's working as expected.

Thanks.
