    Wireless not functioning after fresh 14.04 install

    Hello

    I just installed lubuntu 14.04 on my dell mini 10 (Inspiron 1010) and the Wi-Fi is not fuctioning at all.

    I have followed all the steps in the " [SOLVED] How to install a driver for the Broadcom series of PCI wireless cards " thread but yet I have no wireless internet.

    My ethernet seems to be working just fine though.

    Here is my wireless script report if that helps
