I have an old HP Mini 110-1026NR netbook. I recently installed Ubuntu 14.04 LTS 32bit. I am unable to connect to wifi and I do not have an ethernet cable, but I do have a working mac and a flash drive. The netbook has a Broadcom chipset BCM4312 and its PCI-ID is [14e4:4315]. The current kernel in use is b43-pci-bridge. Please help.
