[EN] [SOLVED] Can't connect to wifi network

[luispa]

Hi,
This is my first post here. I used Siduction in the past and never had issues with the Broadcom 4312 wireless card. I installed the broadcom-sta-dkms. The wl module loads without issues and nm-applet show the available wifi networks but when I try to connect to my home network it asks for the password again and again and never connects.
I also disabled Network Manager and tried with ceni, no luck but I had more information about what could cause the problem. This is ceni output when trying to connect:

I would really appreciate information about how to solve this issue.
Thank you very much in advance,

Can you provide the pci-id for the device? lspci -nn  should provide it.
You do not get a lease from dhcp, that is why there is no connect.

Thank you very much for your reply
This is the output of lspci -nn

Thank you again,

I have the same wireless chip.  The driver that works here is b43-pci-bridge.  From

Code: [Select]

lspci -vnn

Code: [Select]

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
        Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at f1ffc000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: b43-pci-bridge

Somewhere on this forum last year I posted how to install it, because this laptop has a broken ethernet chip.  I will look for that post.


EDIT: Here is the old post.

Thank you very much! I'll try with this driver and I'll let you know
