WiFi keeps disconnecting all the time - Cinnamon 17.2

[moho70]

Good morning all
I have the problem that the WiFi is disconnecting all the time. I updated to 17.2, but it started, when I start to use another Wireless Modem (I'm renting the apartment). I (a friend) updated the driver for the WiFi card, the kernel and fixed the BT as well. But the problem with the connection continued...I'm getting crazy, no Skype, videos etc.
I installed Mint almost 1 year ago, and I love it, but this issue is annoying me very much.


ASUS X750LN, the card is a Broadcom
I paste the result of the command:

I think it is this driver:

bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu4_amd64.deb ?

[kc1di]

your card works better with the other broadcom driver - b43 do the following in a terminal
connect to a LAN by cable first. (ethernet)

Code: Select all

sudo apt-get purge bcmwl-kernel-source 

then this

Code: Select all

sudo apt-get install firmware-b43-installer

When that is finished reboot. if wifi does not work you may have to blacklist the wl driver.

[moho70]

I did it, but now there is no WiFi option at all?
blacklist the wl driver?

[kc1di]

No lets back up

purge firmware b43 and reinstall bcmwl driver.
Then go to this page and install newer kernel.

seems there was a bug that affected some wifi card up until 3.18 kernel.
I upgrade to the 4.1.2 kernel which is the latest stable kernel without problems.
here is how:
http://mintguide.org/system/456-install ... -mint.html
Others with you card have report that it solved the problem of drop out. I don't have any machine with that card at the moment so can't check it out for my self.
good luck
