Wired still connecting

All I did just rebooting. Wired connection still connecting (connected to my router) but the WiFi still working, but it unstable. How do fix it? And yes, I replugged the cable

If you happen to have Broascom WiFi like myself, you need to use an additional driver. You can check it by opening "Additional Drivers" from Application menu.

I don't use Broascom WiFi. It keep disconnecting and connecting

Can you issue this command in terminal

lspci

and paste the output here?

This shows on output

[*] The build has failed! Please make sure you have all dependencies installed and you are building on the correct branch (kernel version, not linux distro version, is most important for the branch)

Can you try seeing if modprobe can pull it from the kernel?:

sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce

No need. So all I did is just connecting drive to VMware. I booted up, shut down and plug back to computer and now the Wired connection works. Weird ...
