Okay, so I recently downloaded Ubuntu and installed it to run alongside Windows 7. When I started Ubuntu, I could not find my WiFi network in the network list. My ISP (Internet Service Provider) is Iburst (now Vox Telecom). It's been maybe two months now and I still can't find my WiFi network. My PC is rather new, and I later installed the exact same Ubuntu onto another, older laptop. It works just fine and it can find my WiFi network... What could be wrong?
My output when I run: lspci -nnk | grep 0280 -A2
05:00:0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0510]
Kernel driver in use: bcma-pci-bridge
I tried the answers in Installing Broadcom Wireless Drivers, that @chili555 suggested but none of them worked. I tried everything, installed both the package in the list, and the one for after September 2016... I still can't find my WiFi network in the list...
lspci -nnk | grep 0280 -A2
Then edit your question to add the result. – chili555 May 16 '16 at 13:40
