No wifi after installing linux

Post by leriander »

So I don't have wifi after installation and in /drivers it says "Drivers cannot be installed connect to internet" and "No proprietary drivers are in use". I'm using Acer extensa 5220 with Netlink bcm5787m. IF anyone know how how to fix this I will be happy :D

Do you have a working ethernet connection? Post the results of this command in Linux Mint terminal

Code: Select all

lspci -nnk | grep -iA3 net

There was "Ethernet wired connection 1" or something like this, but as it says "wired" I thought it may be a problem and deleted it from network manager.

Here is what terminal says:

02:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express [14e4:1693] (rev 02)
Subsystem: Acer Incorporated [ALI] NetLink BCM5787M Gigabit Ethernet PCI Express [1025:011c]
Kernel driver in use: tg3
Kernel modules: tg3
04:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
Subsystem: AMBIT Microsystem Corp. BCM4311 802.11b/g WLAN [1468:0422]
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb

BRW: Sorry f I don't understand something. It's my first time ever with linux :D

Of course that's your choice, but I've seen threads for broadcom wifi go for pages, many posts, and no resolution, across a week or longer. It just depends on how much time and effort you are willing to spend on it to determine if you will be a lucky broadcom wifi user, or not. You can try newer kernels, see if that solves it for you.

Download the attached file and copy it to the Linux Mint desktop, right click on it and choose "extract here", then in terminal

Code: Select all

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/* /lib/firmware/b43
sudo modprobe b43
Then reboot

What command gave that error? Linux is case sensitive so the commands have to be exact

Did the b43 file actually extract, it should have created a b43 folder on the desktop
