My laptop is Dell Inspiron 5520, the wireless network is BCM43142 which doesn't work properly after upgrading to 15.10.
It works for a while and stop working without any error or notification, after a minutes or two or after disabling/enabling the network it start working again. This cycle never stops!
I'm suspicious that the problem was there before upgrading but I'm sure it got worse.
I've purged and reinstalled bcmwl-kernel-source
but nothing changed.
How can I figure out the real problem?
