I've been struggling with the WI-FI support of my system for last few days! I've upgraded my ubuntu ver. from 18.04 lts to 18.10. After doing this, my WI-FI was okay for 5-6 days but after that it started disconnecting automatically after every 4-5 mins even when the signal seems to be appear, then I have to restart the network manager again and again periodically after 4-5 mins! Your help will really help me a lot. Here I've posted few more details, Have a look :
