WiFi issue
I am new to linux. I am using linuxmint 17.1 Rebacca on a Compaq laptop. The laptop has a Broadcom wireless driver 802.11 which was connecting alright to my home WiFi network. Today, all of sudden it won't connect to this network. I did not change any settings of the router or my laptop. What should I do??

Re: WiFi issue
Have you maybe installed updates from level 4 and 5? I've experienced that they broke the Broadcom wifi on a laptop....

Re: WiFi issue
Unfortunately, I don't know how to roll those updates back... At the time, I "solved" it by re-installing Mint. And then I made all updates for level 4 and 5, including the security updates, invisible in the preferences of Update Manager.sagarbjmc wrote:It seems i have. what should i do now??Pjotr wrote:Have you maybe installed updates from level 4 and 5?

Re: WiFi issue
You must connect to ethernet and use no flash or usb wifi sticks, ethernet through a dhcp wifi router is fine, best actually.
you're problem is simple with any distro:
For PC, it defaults to MAC OSX and will not work in 17.1, honestly with macchanger in 16-17.1
so you have to prgram it to do what you want automatically without cessation.
no usb wifi, ethernet only
open a terminal.
1. sudo nemo /etc/modprobe.d
select file > *blacklist.conf* by double clicking it; and opening it as a text file
then, after the first line containing a #, space to a new line
type: mac80211
* this will blacklist your wifi instruction from trying to use a mac osx broadcom card, which uses, per se, appletalk for Mac OSX, not pc
save the file, close the file.
close nemo
back to opened terminal
2. sudo apt-get install firmware-b43-installer
let it finish and no usb wifi sticks or you'll have to do it again. you shouldn't need one now
reboot
wifi works permanently and has true b43 with a capacity for macchanger working properly, and never quits or cuts off
* I realize what happened is they defaulted back to the version of b43 installer from ubuntu 10, pre-unity!! and it just defaults to MAC80211, so a pc runs a mac instruction set for pc nic, and broadcom or b43 for mac is not compatible with pc. ::Appletalk is why:: PC Wifi NICs don't use the same language as a mac one.

Re: WiFi issue
well, today when i started the computer the wifi network was detected. And it connected alright. I didnt do anything much yesterday..... looks the problem got solved by itself. Thanks guys for all the help.
Re: WiFi issue
[Solved]
Now, actually you have to use mac80211 for cfg80211, because they are softmacs, etc, you can read it if you want. After three times, the blacklist and etc was broken. to use it with macchanger, due to router's that use n specs, there's no country code etc that's an immediate problem. to use macchanger and wifi and have wifi connecting if it does not, clear your net settings completely and restart network manager.
In the old days, this would suffice:
sudo ifconfig wlan# down
sudo macchanger -m xx:xx:xx:xx:xx:xx wlan#
;or, sudo macchanger -A wlan# <for a random one>
sudo ifconfig wlan# up
then connect using the wifi manager atop on right.
****^^^^^^^ this no longer works.
you have to add a few things when it will not connect:
regular (if you do not want to hide your address from public viewing:
see your wlan# with:
ifconfig
sudo service network-manager stop
sudo ifconfig wlan# down
sudo ifconfig wlan# up
sudo service network-manager start
for macchanger:
sudo service network-manager stop
sudo ifconfig wlan# down
sudo maachanger - A wlan# <or> sudo macchanger -m xx:xx:xx:xx:xx:xx wlan#
sudo ifconfig wlan# up
sudo service network-manager start
it will connect every time if you do this:)
