I have installed the new Ubuntu 14.10 on my Dell Inspiron 3521.
I was able to use my wifi in the Boot Live Stage and during the Installation phase by enabling the BroadCom BCM 43142 proprietary drivers.
But after installation I can't enable the proprietary drivers.
I can see the drivers listed there and when I select the option to use them and click Apply, the progress bar starts going ahead but stops in process and the 'Do not use them' option gets reselected.
I have searched some questions here according to which I must connect my laptop with an ethernet cable to get my wifi drivers working.
But I don't have any ethernet cable at present with me. I can only use the wifi on my second laptop.
Is there any other way to get the drivers working or Is there any offline installer like a .deb file for the drivers?
If anyone knows, please help!
I've reinstalled ubuntu thrice but the problem remains same.
