Hi
This is a question about Broadcom BCM43225 wifi interface on an Acer Aspire laptop
I just had a fresh install of ubuntu 16.04 on my acer aspire laptop and I am having a difficult issue with my wifi connection. Every time I restart my laptop I get the wifi connection working, but after a while (max 10 min) I lose connection, and the wifi is not listed in the NetworkManager any more (says disconnected) and I can only get it back via restarting the laptop.
Here is the output of sudo lshw:

If I have no wifi connection, this output will not have the wifi hardware (Broadcom) listed among networking!
I already have installed the BCMWL-Kernel_Source package.
What should I do?
