    Wifi Won't Connect Anymore?

    Hi, I've having trouble with my wifi on my Acer Aspire running 13.04. It's had no trouble with wifi before this, and still scans for all the networks around here. For some reason though, it won't connect to my home connection anymore. It will scan and scan, but won't connect to the internet. I tried searching for an answer on the forum, but the problems don't seem to be the same and the solutions don't work.

    I'm using a different computer to respond, but nothing is hard or soft blocked, and the network controller came up as Broadcom BCM43225

    It shows brcmsmac in red on each line, and it returns 14e4:4357. Thanks

    Strange, it guess it was router issues, even though there were other functioning devices on the same network. Thanks anyway

    Now I'm having the same issue, if it is router related, I cannot understand why the computer I am on now is able to connect to it, but it seems to correlate with router problems

    Re: Wifi Won't Connect Anymore?

    Let's blame the driver once again (why, because we can ), and try another one. Assuming you have a wired connection available, please do -
    Code:
    sudo apt-get install linux-firmware-nonfree
    sudo modprobe -rv b43 brcmsmac
    sudo modprobe -v b43
    Any improvement?
