    On 13.04 Cannot connect to password protected Wi-Fi Router BCM4313

    Since going to 13.04 I have not been able to connect to the wi-fi feature of my ADSL modem which is password protected using WEP. I can connect to wi-fi hotspots, for example at coffee shops. When I try to connect to my local wi-fi modem the system tries for a while, pauses, and then tries again. There is no diagnostic message that I can see. Everything worked fine on 12.04 and 12.10. According to the web the only eligible driver for the BCM4313 is the proprietary STA driver, which is what I have activated. System > Software & Updates > Additional drivers only gives me the choice of using the proprietary driver or not using the wireless at all.

    Re: On 13.04 Cannot connect to password protected Wi-Fi Router BCM4313

    According to the web the only eligible driver for the BCM4313 is the proprietary STA driver, which is what I have activated.
    I think there is another way and I suggest you try it. Maybe we can try it temporarily before we take a hammer and saw to your system. Please open a terminal and do:
    Code:
    sudo ifconfig eth1 down
    sudo modprobe -r wl
    sudo modprobe brcmsmac
    If there are any errors, warnings or other messages, please post them. Now do you have a wireless interface wlan0?
    Code:
    iwconfig
    Will it scan?
    sudo iwlist wlan0 scan
    Does it connect?

    If so, I'll sharpen my saw and we'll make it permanent.

    That connected. Could you explain why it was not working and what my next step is?

    According to the web the only eligible driver for the BCM4313 is the proprietary STA driver,
    That is incorrect. As you saw, when you unloaded it and loaded the correct native driver brcmsmac, it connected as expected. Let's fix it:
    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    Reboot and you should be all set.

    Re: On 13.04 Cannot connect to password protected Wi-Fi Router BCM4313

    Thank you for your help. I am puzzled though. When I go to System > Software and Updates >Additional drivers it now displays for the BCM4313 "This device is not working" and "Do not use the device" is selected, even though my laptop is now connected to the wi-fi network. How is a non-expert user to figure this out?

    There are bugs, unfortunately. The Addtional Drivers tool attempts to be all things to all Ubuntians but misses on 3-4 Broadcom devices out of dozens.

    I recommend you ignore the tool and enjoy your wireless. I am sure the developers are working on it.
