I have a wireless card that needs the Broadcom B4311 Rev. 1 driver but I don't have a way to download that driver since I don't have wireless access since the driver isn't installed.
I'm running Linux Mint Debian x64.
You can download a few files from another computer and install the firmware.
There are instructions here http://wireless.kernel.org/en/users/Drivers/b43
For a similar chip (which probably uses the same firmware) there are more straightforward instructions: https://wiki.ubuntu.com/Testing/Laptop/Lucid/Reports/AcerAspireOneD150#Post-install%20fixes
Been in this exact situation with my E1505. Easiest way is to go out and buy a network card to plug in, and then return the card.
But if that's not an option, you can follow the instructions here, but make sure to replace any reference to Ubuntu with Debian.
