I had a very similar issue on peppermint 6 with an HP laptop once before, it used realtek. I posted here about that issue, followed all the advice and it worked temporarily. Once it stopped working I undid everything I changed and it hasn't stopped working since.
This new issue is different. It is an Asus laptop using Broadcom proprietary driver. I am using peppermint 7. Yesterday I installed the OS and wifi was working, I installed updates and then browsed the internet (over WiFi) for a few hours before turning it off and going to sleep.

I cannot see any wireless networks available and obviously couldn't connect to the internet until I plugged in a ethernet cable. It connects using ethernet.
The wireless adaptor built into this laptop says Broadcom Corporation: BCM4352 802.11ac and I have the option "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernal-source(proprietary)" ticked on.
There is no other option besides do not use the device, so no open source driver is available.

I've tried a few things but I've been unsuccessful in finding a solution online, so since I'm not the most tech-savy I haven't done anything in the terminal (though I'm not afraid of it if someone can help).

I deleted the saved networks and turned the adaptor off rebooted then turned it back on.
I selected do not use the device, then reselected the driver.
After looking through the updates I installed yesterday I saw that the kernal was updated to 4.4.0-70, and when I first installed peppermint it was on 4.4.0-66. After updating to the new kernal it was still working, but I went back to 4.4.0-66 and its still having the issue. None of the installed updates look network related, but again I'm not an expert.

Also worth noting that the wifi is still working on the windows 8.1 partition on this laptop, on my hp running peppermint 6, and a couple other devices. The Asus laptop and the Xbox are the only things in the house that use the 5 Ghz network, and the Xbox is connected.

Hi DisturbedOne, how's it going?  Have you tried checking for additional drivers?  If you haven't, follow these directions. 

With your laptop connected to the internet with an ethernet cable, navigate to:

menu > Preferences > Software & Updates

In the new window that opens, select the:

Additional Drivers

Let it complete its search for drivers.  This could take a few minutes.  If the BCM4352 802.11ac driver is found, click on Apply Changes and follow the instructions.  I hope this helps - good luck and have fun  ;).

AndyInMokum, the only driver for the adaptor is the one already active, which is Broadcoms proprietary driver.

You missed the "-vnn" switches out of
Code: [Select]
lspci -vnn | grep -i net
???

There is nothing in that output that could be considered a security risk if that's your worry.

maybe the driver just needs recompiling against the new kernel .. with a wired connection try this
Code: [Select]
sudo apt-get remove --purge bcmwl-kernel-source
Now reboot.

Once rebooted, run:
Code: [Select]
sudo apt-get install bcmwl-kernel-source

and if that doesn't work, can you post the output from
Code: [Select]
lsmod

I do believe that worked! I'm posting over WiFi on the problem machine!

Thank you very much.  :D
