  • How it is a duplicate my kernel driver in use is rtl8723be and in the duplicate you given kernel driver in use is rtl8723ae – Rohit Robichan Jan 08 '18 at 16:16
  • I have reopened the question but please [edit] and give us more information. What version of Ubuntu is this? You need to tell us the actual version in your question, don't just tag with "Edubuntu". Also show us the output of running dmesg | tail -n40 just after it disconnects so we can see what errors are printed. – terdon Jan 12 '18 at 15:53
