This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • You might want to look into some log files when you try to start the WiFi. tail -f /var/log/{daemons.log,syslog,messages,dmesg.log} How do you try to start it? Have you set it up with WindowManager? If you look into dmesg.log, do you see some complainings of firmware? You might need to install the packager firmware-linux-nonfree. That is usually the problem with these Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter. – Anders Mar 9 '15 at 16:41

Do:

echo "blacklist b43" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot and wifi should be working.
