Solution For No Ethernet(LAN) In Ubuntu [That Worked For Me]

Not a tutorial but a quick note, I don't know if this works for you or not but this worked for me. Earlier, my system was not showing the ethernet interface and I tried lots of stuffs to find the solution. Just a thought came across my mind and then I turned off my laptop and removed the battery and then inserted the battery after a while. On booting to the system, I found the ethernet to be working. Maybe this might help you sometimes so putting up this small note.
