I'm a new Linux user. Strong Windows user but not a programmer. I installed Ubuntu 14.04.4 on my old Dell Inspiron 1501. I am not able to connect to my Home network via Ethernet or wifi. I'm not able to toggle wifi on.
sudo lspci
Result is:
Network controller: Broadcom Corporation BCM4331 801.11b/g WLAN (rev01)
Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev02)
Do I just need the firmware-b43-installer? If so how can I get it on a USB drive and install from there?
EDIT:
Installed b43-fwcutter_018-2_amd64.deb then firmware-b43-installer_015-9_all.deb but received and error that it could not access broadcom-wl-5.10.56.27.3_mipsel.tar.bz2 from the mirror.
I have broadcom-wl-5.10.56.27.3_mipsel.tar.bz2 on my USB drive but don't know how to get the installer to use it.

Was able to get Ethernet working with solution found here: Ethernet Network card BCM4401-B0 no longer recognised?
