intermittent connection, mint 17 /Dell 4050 [SOLVED]

[Oratoide]

Good evening, first of all sorry my English, I'm using google translator.
For a month now I have problems with the wifi connection, my laptop is a Dell N4050, use cinnamon mint 17, reading other threads, it happens something like it --> http://forum.linuxmint.com/viewtopic.php?f=53&t=181088 ,restart, press fn + f2, the wireless network disappears, etc.
Already tired of the problem, update the Kernel 3.16.1, was solved a few days and returned to the same.

Maybe this helps

The errors at the end of the info are troubling but a bug report I found may indicate it is an issue with bluetooth. So we will blacklist bluetooth modules and restart to see if it works better

Code: Select all

echo "blacklist btusb" | sudo tee /etc/modprobe.d/blacklist-blue.conf

Code: Select all

echo "blacklist ath3k" | sudo tee /etc/modprobe.d/blacklist-blue.conf

You will want to enter the code into terminal from a non-translated version of this post as the code may change in translation

Restart computer and see if it is better

And pastebin. :D

Thanks JeremyB. : D
Truth does not understand much, but since I accepted my post, I have received several updates for bluetooth.

I did what you asked:

@ sebastian Sebastian-N4050: ~ $ echo "blacklist btusb" | sudo tee /etc/modprobe.d/blacklist-blue.conf
[sudo] password for sebastian:
btusb blacklist
@ sebastian Sebastian-N4050: ~ $ echo "blacklist ath3k" | sudo tee /etc/modprobe.d/blacklist-blue.conf
ath3k blacklist
@ sebastian Sebastian-N4050: ~ $

I rebooted my laptop and this is my pastebin:
