[Solved] High sierra internet stopped working

[talavoock]

Hi everyone.
I have high sierra 10.13.6 and TP-Link Archer T9E wifi. after i updated some security update from mac app store then audio stoped working. i installed voodoohda but didn't work then i installed AppleALC.

Audio fixed and everything was ok for 3 days i had no issue.After 3 days when i turn on my pc, it didn't boot and when i reboot then it booted but with no internet connection.

WiFi is connecting to AP and assigning IP with DHCP and i have PING to my router.but still no internet connection if i reboot about 20 times maybe i get internet connection one time but when shut down or reboot again then no connection.

I tried these below ways, but still no connection:

• Edit location in network preference
• Reset router and reboot my pc
• Reset nvram
• delete all network system configuration
• disabled some lunch agents
• tried some bootflags
• connect to another router and tried mobile usb tethering(usb tethering was working before this issue)
• boot with safe boot
• open wireless diagnostics...
• Add AirportBrcmFixup.kext to EFI/CLOVER/KEXTS/Other

I have been using hackintosh since 2 years ago.but never had this issue.
And i have Mojave on another SDD, internet is working well with same WiFi TP-LiNK archer and same Router.

I searched a lot and tried some other ways still no internet connection.
I appreciate your help

I managed to solve this problem after one day trying. Unistalled same old vpn launch agents by CleanMyMac3 and it is working now.
I rebooted and shut down many times just for test and it is still working.
