Hi, I was having problem with wifi in ubuntu 18.04 lts after having recent upgrade, so I followed the steps mentioned here - https://askubuntu.com/questions/1058...with-rtl8723be, but was not able to solve the problem, in another answer I read that upgrading to 18.10 (kernel version 4.18.0-15-generic) will solve the problem but all in vain. Please help to resolve the problem.
