I have had Ubuntu 16 for 1.5 years now and had no issues until 3 months ago when my laptop would not connect to new wifi networks i.e. it connects automatically to those that I had passwords saved and while it detects new available networks I cannot connect to those, also nothing happens if I try clicking on settings for these in network manager. I don't even know where to begin. Thanks.
