[Mint17Xfce] Broadcom 4313 with BCMWL

[iAN123]

hi!

I know, there are a lot of similar posts, but I'vent found any solution on my problem.

I've got an Acer Aspire One 722 with wireless card Broadcom 4313

Code: Select all

07:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

System: Linux Mint 17 XFCE
Kernel: 3.17

I tried to use opensource driver (called brcmsmac) but signal is really weak and I can't use my notebook as normal. In previous version of Ubuntu and Mint (ex. 13.10, 13.04) I used bcmwl, but here I couldn't install it - still show:

Code: Select all

module: wl NOT FOUND

After few days I found and installed special patch from Launchpad and now I can load wl module and my wifi card see every network, but still it can't connect to any of them.

Have you any ideas?
Thank you very much for help!

Regards!

PS. Maybe somebody know how to use brcmsmac with better signal?

I wonder why it said not found, when this last post says kernel driver in use: wl
Lets try getting rid of wl

Code: Select all

sudo apt-get purge bcmwl-kernel-source

Reboot and post results of

Code: Select all

lsmod

and

Code: Select all

ls /etc/modprobe.d/

I think you didn't understand what I mean.

Now, after installation a patch I can load WL, but I can't still connect to any of networks (although I see it in Network Manager)

[JeremyB]

Do you have a link to the patch?

I think this chip works with brcmsmac and bcma with b43 and ssb blacklisted

https://launchpadlibrarian.net/18319065 ... 3.17.patch

With kernel 3.11 everything worked.

With kernel 3.11 everything worked.

Why the switch to 3.17?

[iAN123]

I thought about previous version of Ubuntu (13.10).

I switched to 3.17 because of my APU with AMD Radeon.

Do you see any results from

Code: Select all

modinfo bcma | grep 4727

Code: Select all

modinfo brcmsmac | grep 4727

[iAN123]

Code: Select all

modinfo bcma | grep 4727
alias:          pci:v000014E4d00004727sv*sd*bc*sc*i*

and

Code: Select all

modinfo brcmsmac | grep 4727
NOTHING

Code: Select all

modinfo bcma | grep 4727
alias:          pci:v000014E4d00004727sv*sd*bc*sc*i*

and

Code: Select all

modinfo brcmsmac | grep 4727
NOTHING

I just got home and looked at the full output from brcmsmac and it does work with bcma but have to see if they are blacklisted first

Code: Select all

ls /etc/modprobe.d/[code]

hi,

Thank you very much for help. Now my problem is I think solved.

I tried every new kernel and Broadcom Driver works on 3.13.0-24-generic.

Regards!
