How can I solve the issue with driver support?

Hi, all. I'm totally newbie in bsdFreeBSD and I want to ask about driver support.
(I've used Gentoo linux and Arch linux...But I decided to move onto bsdFreeBSD.)

I tried to install bsdFreeBSD on my laptop few months ago, but I faced to driver issue with Intel 7260 wireless support at that time. I'm not sure that the issue is solved now.

The result of lspci is like this:
Code:

I want to know whether I can enjoy freebsdFreeBSD on my laptop. If not, is there any alternative BSD? or do I have to wait until the driver is supported?
 
I faced to driver issue with Intel 7260 wireless support
This driver is under active development by Rui Paolo and Adrian Chadd, but is not yet included in FreeBSD.

If you want to try the early development driver, you could do the following (note you will need a different network connection to download packages):
  1. Ensure you have the FreeBSD source code for your release available in /usr/src. You can select the source code to be installed during the FreeBSD installation.
  2. Install the git package: # pkg install git
  3. Check out the latest driver code into your home directory: $ cd ~/ && git clone [URL]https://github.com/rpaulo/iwm[/URL].git
  4. Build the driver: cd ~/iwm/ && make
  5. Install the driver and firmware: # cp driver/if_iwm.ko driver/if_iwm.ko.symbols iwmfw/iwm7260fw.ko /boot/kernel/
  6. Load the driver: # kldload iwm7260fw and # kldload if_iwm (consider adding entries to /boot/loader.conf to load the driver at boot time)
  7. Configure your new iwm0 interface by following the normal FreeBSD handbook chapter: https://www.freebsd.org/doc/handbook/network-wireless.html

Good luck!
 
I’ve seen that there could be a regression in current

I am not convinced that is actually a regression in CURRENT. I believe it could be the result of a recent change in current to make it such that wireless "parent interfaces" are no longer listed in the output of ifconfig(8), but instead they are listed in the output of # sysctl net.wlan.devices. Other than that there is no change to the configuration required to bring up wireless devices. We are waiting on the bug reporter to confirm this is the case, and that there is no regression.

The change that brought this difference in behaviour was committed to current on 20150827 in r287197:
https://svnweb.freebsd.org/base?view=revision&revision=287197

This update was described in the following UPDATING entry:
Code:
20150827:
The wireless drivers had undergone changes that remove the 'parent
interface' from the ifconfig -l output. The rc.d network scripts
used to check presence of a parent interface in the list, so old
scripts would fail to start wireless networking. Thus, etcupdate(3)
or mergemaster(8) run is required after kernel update, to update your
rc.d scripts in /etc.
 
iwm(4) is working nicely for me in FreeBSD-CURRENT since r286441.
Hello, sorry to butt in, but there is only scarce information about the iwm(4) driver under FreeBSD.
I have problems getting iwm(4) working with an Intel Dual Band Wireless AC 3160 (I have a Zotac ZBox RI323). The console message states
Code:
fatal firmware error
...
could not move to auth state: 35
.
Now, this could be MB/FW related, but as a BIOS Update is only possible under DOS/Windows, I would like to confirm that there are no known problems with the iwm(4) driver as such (I have build CURRENT at r290151).
I am thinking about starting a new thread here under System Hardware, but it would be nice if you could tell me a bit more about your experience with this particular driver beforehand.
 
Hello Zipferlake.

You should open a PR. As the manual page says, fatal firmware errors should not happen. On the other hand, the iwm(4) commits state that the driver is not very stable yet. I’ve had some crashes with it, seemingly when rebooting just after some heavy network usage, but I have not had the time to investigate. Besides that, it is working well out of the box for my humble needs: no roaming, moving from a room to another at home.

Could you explain the steps leading to the error?
 
Hi Juanitou, thxthanks for taking an interest.

The error occurs when I try to connect to an AP after the following steps: loading kernel module+firmware, creating wlan0 interface and starting wpa_supplicant(8) (see messages below - posting here as file upload does not work ...).
Code:
kldload if_iwm
ifconfig wlan0 create wlandev iwm0 wlanmode sta ssid NET.HAYAT_WLAN_01 channel 7
/etc/rc.d/wpa_supplicant start wlan0

I have an old VIA Epia ML Board with an PCI Atheros 5212 WLAN Card working under FreeBSD 8 just fine connecting to the same AP (I copied the wpa_supplicant.conf, so I know it is not a configuration problem)

Sorry, I cannot help. In my case, I had to add WPA to the ifconfig(8) configuration for the authentication to work and there is no wlanmode sta, but I don’t think this is relevant, neither I remember having firmware errors before I discovered the correct parameters. I reckon you have all the information needed by developers to discover where the problem lies. Please open a PR.
 
Hi Juanitou,

thanks for Your input! - By the way, what chipset do you have AC 3160 or 7260?

In the meanwhile I have installed CentOS7 on a second disk and I have run into similar errors; the WLan interface can be created, I can even scan and find my AP but I cannot connect (though the error message is somewhat obscure).

Therefore and with your insurance, that apart from minor problems the iwm driver should work, I suppose I have to try and update the Firmware on my MB (even if I have to find a means to get a DOS Boot Stick or a DOS PXE Bootimage). If the error continue I will certainly open a PR.

Regards, Stefan
 
Quick question: has anyone tried the iwm(4) driver (from -current) in FreeBSD 10.2-stable? AFAICT it is not MFC'ed yet.
I've just got myself a new laptop, and it has a Wireless 3160 inside. The laptop is so new that I haven't installed FreeBSD on it yet.

As you say, it has not been merged from current to FreeBSD 10-STABLE yet.

There are a few bugs in the iwm(4) driver (wifi tends to report a number of errors and require regular resetting of the wifi NIC). Unless these are sorted out, I doubt this driver will be MFC'd.
 
After installing latest FreeBSD 10.2-STABLE on my new laptop, I decided to see if the iwm(4) driver would build on -STABLE, so I checked out the source from -CURRENT and had a go.

You may have better luck taking the diff that added the feature you want and trying to patch the driver with that diff, rather than trying to import the whole driver. Sometimes the change you want has few or no dependencies on changes to driver style that may exist between any -STABLE branch and HEAD.
 
Yes. Unfortunately, this driver was built/created in -CURRENT; it didn't exist in any other branch, AFAIK. So there really isn't any diff or anything to patch. :)

Oh well - it was worth a try. Two other ideas:

1 - You could contact that developer and ask if they have a version for your FreeBSD release, and offer to test it thoroughly and report back. In some other cases I've done that and it has resulted in either the driver getting MFC'd or at least definitively knowing that it won't work on an older release.

2 - You could do a diff on a similar driver that exists in both your FreeBSD release and CURRENT, to get an idea what sort of changes were made to the driver structure, then try to edit the driver you're interested in to reflect those same changes. I've also done this in the past.
 
I just installed FreeBSD-CURRENT (r292858) on my Thinkpad X240, activating the if_iwm(4) module gives the following output:
Code:
iwm0: <Intel Dual Band Wireless AC 7260> mem 0xf0400000-0xf0401fff at device 0.0 on pci2
iwm0: revision: 0x140, firmware 25.228 (API ver. 9)
However the interface is not present in the output from ifconfig. Any ideas on how to debug/solve this issue would be much appreciated.
 
I managed to get iwm working on FreeBSD 11 CURRENT,
ifconfig wlan0 create wlandev iwm0, and everything works good.

But I can not get it created during boot.
/etc/rc.conf
Code:
...
hostname="raya1.rayit.com"
wlans_iwm0="wlan0"
ifconfig_wlan0="WPA DHCP"
#ifconfig_wlan0="-ht WPA DHCP powersave country NL"
...
/boot/loader.conf
Code:
...
if_iwm_load="YES"
iwm7265fw_load="YES"
#iwm7260fw_load="YES"
legal.intel_iwm.license_ack=1
...

Somebody any idea?

What revision are you running? And do you get the fatal firmware error when trying to create it at boot?
I'm also on CURRENT (r293687), iwm and associates compiled into the kernel and getting the error (on boot and after). Can't seem to get the ac7260 up and running..
 
I updated from 10.2 to 11-CURRENT, and after adding 3 lines to the boot loader I could run:
ifconfig wlan0 create wlandev iwm0
I do not see fatal firmware errors.

So the iwm(4) code is already in 11-CURRENT.
I will look this evening what version and laptop I have.
