    Re: Wifi Not getting connected with NC110 Samsung Netbook Lubuntu

    See chili555's post here for disabling power management for wifi, preferred router settings and setting your country code
    If that doesn't help, remove the Broadcom proprietary driver
    Code:
    sudo apt-get purge bcmwl-kernel-source
    Blacklist a couple modules that may conflict
    Code:
    echo "blacklist b43" | sudo tee -a /etc/modprobe.d/blacklist.conf
    echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist.conf
    Reboot

    Is your wifi router on auto channel or did you change it? Many of the Broadcom wireless cards are limited to channels 1-11 in 2.4 Ghz
