Problem working with my wifi connection


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?

That in itself is not enough. Have you tried this:
Code:
sudo apt-get install linux-firmware-nonfree
sudo apt-get install linux-headers-generic
sudo apt-get install bcmwl-kernel-source
sudo modprobe -r b43 ssb wl
sudo modprobe wl

Hi

Thank you for your reply.
I have all these packages installed and I have issued the modprobe command before, I get no errors. The issue is still there.
I am open to any suggestions. I now use wired connections to the Internet.
