wlan0 not found on Ubuntu 13, BCM4313

[HrJ7k64]

Hi I've just installed ubuntu 13 on my lenovo b570e and the wireless isn't working at all and wlan0 won't come up. I've tried various online tips but nothing works.

If i run: lspci -nn | grep 0280

I get the following

02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

Also: iwconfig

eth0 no wireless extensions.

lo no wireless extensions.

Any tips on how I can get this working? It's very annoying. thanks

Anyone?

Install the package "linux-firmware-nonfree" via cable connection

The problem was other drivers being installed. Now i just have brcmsmac installed, however when i click connect to wifi and enter the password it never connects, just keeps prompting me to input the password again (i did it correctly)

Any ideas?

result of: lsmod | grep brc

brcmsmac 550698 0
bcma 41051 1 brcmsmac
cordic 12574 1 brcmsmac
brcmutil 14755 1 brcmsmac
mac80211 606457 2 brcmsmac,ath9k_htc
cfg80211 510937 5 wl,ath,brcmsmac,mac80211,ath9k_htc

also my modprobe blacklist has the following added:
blacklist b43
blacklist b43legacy
blacklist bcma
blacklist ndiswrapper

Please do:

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

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

echo "blacklist ath9k_htc " | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot
Thanks

Did those steps, but it's just as before still

Hi, copy and paste this command in the terminal (ctrl+alt+t) please:

 wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a file named (wireless-info.txt, or wireless-info.txt.tar.gz) in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back, click on the paper clip and attach the wireless-info.tar.gz file as a zip file.

If you do not have ethernet either then follow the directions at this link for running the script without internet.

There is a bug in the driver you are using, you can try the wl driver sometimes it works sometimes it does not.
Please do:

sudo modprobe -r brcmsmac
sudo modprobe wl

Also it looks like you may have an usb adaptor hooked up if so you will need to disconnect it before you can connect wifi.
These commands are just temparary so do not reboot.
Thanks
