Freebsd broadcom wifi driver

Solved Broadcom BCM4313

Hello: the laptop I am working on for our local American Legion post, an Acer «Aspire One», includes a Broadcom BCM4313 WLAN chip on the motherboard. I am trying to get it in operation. I searched the threads on this forum and found an old one from 2012 which had some very useful info, but I figured that there must have been some progress made since then. So, I went to Broadcom’s website and found two Linux drivers for this adapter, one 64 bit and one 32 bit version. I downloaded the 64 bit version and extracted it. There are a ton of files in two main directories, src and lib. At this point, I can’t figure out which to use where.

The ndisgen script uses the ndiscvt(8) utility and other tools to
generate a FreeBSD loadable driver module and a static ELF object module
from a Windows® NDIS driver, for use with the ndis(4) compatibility module.

Yes. That is the thread I mentioned: but it was written in 2012, and I was hoping there would be a more up-to-date solution.

At this point, I am going to use that solution and not worry about any possible update.

OK. I went through that entire exercise, but, apparently, I have several issues.

1) After doing all of that, and after doing wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -dd the output is as follows;

wpa_supplicant v2.6 Successfully initialized wpa_supplicant Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 'default' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant.conf' Line: 1 - start of a new network block ssid - hexdump_ascii(len=8): 53 48 41 4d 52 4f 43 4b SHAMROCK PSK (ASCII passphrase) - hexdump_ascii(len=11): [REMOVED] PSK (from passphrase) - hexdump(len=32): [REMOVED] Priority group 0 ssid='SHAMROCK' wpa_driver_bsd_init: interface wlan0 does not exist wlan0: Failed to initialize driver interface Failed to add interface wlan0 wlan0: Cancelling scan request wlan0: Cancelling authentication timeout

3)Checking in /dev, I find no entry for wlan0, which may not be of importance.

4) dmesg -a | more does not show a wireless LAN adapter at all.

5) Although there is a .INF file associated with all the other Windows drivers, it is never used here.

6) I had thought to replace «wlan0» in all appropriate files with «none1». but that seemed to me to be less than helpful, so I didn’t do it.

Suggestions? Helpful hints?

ifconfig wlan0 create wlandev ndis0

There is Broadcom NDIS HOWTO thread (from 2012).
Also, there is even older NDIS related HOWTO.

I used to use NDIS long time ago, unfortunately do not remember details.

Thank you again. Obviously, I still have work to do. I will say that so far, this is the biggest PITA I have run into while working with this Acer laptop.

The only thing I have left after I get this sorted out is to activate the I2C-based touch pad. and I am not looking forward to doing that.

And, I don’t see how the folks I am doing this for can even remotely appreciate all the work that has been and still is necessary. Many hours.

And they have 5 more of these I have to work on, but at least after this one, the rest should be. easier.

It was straight forward and took 10 minutes with FreeBSD 13.0 and iichid driver for my Dell Precision 7540, however, I couldn’t make it working with FreeBSD 12.1.

I am working with FreeBSD 12.0-RELEASE.

You can still try building that driver, it’s easy, you’ll need to get the kernel src code in /usr/src though.
I guess, in my case the 12.* doesn’t recognize the I2C bus in my computer (it’s too new!).

KenGordon

OK. Getting back, for the moment, to my NDIS issue, I have been reviewing the files concerned.

1) First of all, I may have an error in my rc.conf. Here is the code:

hostname="pharc2" zfs_enable="YES" kld_list="sysctlinfo" moused_enable="YES" ifconfig_alc0="DHCP" wlans_ndis0="wlan0" ifconfig_wlan0="WPA SYNCDHCP" wpa_supplicant_enable="YES" linux_enable="YES" dbus_enable="YES" dsbdriverd_enable="YES" lightdm_enable="YES" cupsd_enable="YES" samba_server_enable="YES"

. That doesn’t look correct to me, but I don’t yet know enough to tell.

2) Here is my wpa_supplicant.conf

network= < ssid="SHAMROCK" psk="Ab2thW3Aohc" >ifconfig wlan0 create wlandev ndis0 ifconfig wlan0 up wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D ndis0 dhclient wlan0

As one can see, the ifconf «create» command is contained there. However, when I then do wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -dd , the output is as follows:

wpa_supplicant v2.6 Successfully initialized wpa_supplicant Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 'default' ctrl_interface 'N/A' bridge 'N/A' Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf' Reading configuration file '/etc/wpa_supplicant.conf' Line: 1 - start of a new network block ssid - hexdump_ascii(len=8): 53 48 41 4d 52 4f 43 4b SHAMROCK PSK (ASCII passphrase) - hexdump_ascii(len=11): [REMOVED] PSK (from passphrase) - hexdump(len=32): [REMOVED] Line 5: unknown global field 'ifconfig wlan0 create wlandev ndis0'. Line 5: Invalid configuration line 'ifconfig wlan0 create wlandev ndis0'. Line 6: unknown global field 'ifconfig wlan0 up'. Line 6: Invalid configuration line 'ifconfig wlan0 up'. Line 7: unknown global field 'wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D ndis0'. Line 7: Invalid configuration line 'wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D ndis0'. Line 8: unknown global field 'dhclient wlan0'. Line 8: Invalid configuration line 'dhclient wlan0'. Priority group 0 ssid='SHAMROCK' Failed to read or parse configuration '/etc/wpa_supplicant.conf'. Failed to add interface wlan0 : Cancelling scan request : Cancelling authentication timeout

It seems obvious to me (perhaps I am wrong) that ndis0 does not exist.

3) Lastly, here is my bcm4313 executable in /etc/rc.d which does show up in the boot process as loading the drivers.

#!/bin/sh # PROVIDE: bcm4313 # REQUIRE: NETWORKING # BEFORE: LOGIN # KEYWORD: nojail . /etc/rc.subr name="bcm4313" start_cmd="$_start" stop_cmd=":" bcm4313_start() < echo "Loading Broadcom BCM4313 NDIS kernel modules." kldload bcm43xx64.cat.ko kldload bcmihvui64.dll.ko kldload bcmihvsrv64.dll.ko kldload bcmwl63a.sys.ko >load_rc_config $name run_rc_command "$1"

This appears to be working correctly.

At this point, I am kinda stuck.

Broadcom NDIS HOWTO

Here is a quick HOWTO get Broadcom BCM43xx based wireless interfaces working with Windows driver via NDIS, instead of using native bwn which may not be reliable with some devices. There are pieces of information available on how to get it working here and there, so I thought I’d assemble the knowledge at one place. This procedure works well on my Lenovo G550 laptop with the BCM4312 802.11b/g LP-PHY card, running FreeBSD 9.0-RELEASE-p3 (amd64).

There are a few reasons I decided to use the NDIS driver instead of native bwn:

• bwn reporting Fatal DMA errors with my card and disabling DMA does not help
• bwn is limited to the 11b mode only
• bwn floods console with various error messages like unsupported rate 0, etc.

Step #1: Download and extract the Windows driver. I’ve used the Broadcom_BCM43xx_5.100.235.19_win5x.exe file available at [WikiDrivers].

Step #2: Follow instructions in the FreeBSD Handbook in order to create the FreeBSD kernel module out of the Windows driver’s binary and information files. The procedure is well described in the Handbook, so I will just mention that you will need to use bcmwl564.sys for amd64 systems, and include bcmwlcoi64.dll when ndisgen(8) asks for any supplemental files.

Step #3: Copy the newly generated kernel module to the correct place:
# cp bcmwl564_sys.ko /boot/modules/

Step #4: For some reason, loading the kernel module during the boot causes kernel panic for me, so just comment out old bwn modules and simply enable NDIS during the boot time at this step. In /boot/loader.conf:

ndis_load="YES" if_ndis_load="YES"

Step #5: Edit /etc/rc.conf to add interface, here is my example to connect to my Deneb home router at startup:

network_interfaces="ndis0" wlans_ndis0="wlan0" ifconfig_wlan0="mode 11g ssid Deneb WPA DHCP"

Note: Deneb is the SSID of my home router. Replace with whatever SSID you want to associate with on boot.

Step #6: Use kldload(8) to load the Broadcom kernel module during the boot in order to avoid kernel panic. For this, create /etc/start_if.ndis0 with the following contents:

mod="bcmwl564_sys" if ! kldstat -n $mod >/dev/null 2>&1; then kldload $mod fi

Step #7: For some reason dhclient(8) does not work with the wlan0 interface by default if I use the NDIS driver. This has been covered in a few topics on this forum and I do not see anybody resolving this so far, so I use a workaround. Add the following command to the /etc/rc.local:

This will start dhclient(8) during the boot. Don’t forget to configure your /etc/wpa_supplicant.conf normally like you would do with any other driver in case you are using WPA. I don’t use any special flags.

Here is ifconfig(8) showing wireless ndis0 and wlan0 interfaces after reboot:

ndis0: flags=8843 metric 0 mtu 2290 ether 00:26:82:f1:6b:5e nd6 options=29 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g status: associated wlan0: flags=8843 metric 0 mtu 1500 ether 00:26:82:f1:6b:5e inet 192.168.100.103 netmask 0xffffff00 broadcast 192.168.100.255 nd6 options=29 media: IEEE 802.11 Wireless Ethernet OFDM/54Mbps mode 11g status: associated ssid Deneb channel 11 (2462 MHz 11g) bssid 00:1e:e5:46:26:e1 country US authmode WPA2/802.11i privacy OFF powersavemode CAM powersavesleep 100 txpower 0 bmiss 7 mcastrate 6 mgmtrate 6 scanvalid 60 protmode CTS roaming MANUAL bintval 0
