802.11ac support

[kiokoman]

hello,
I'm here to ask some information,
I have this card on my system http://www.sparklan.com/p2-products...hJnAq1DolkcoSJibeSaxmPjpTYdltrQ-f&WPEA-352ACN
I have compiled ath10k driver and it work but I can configure it only as 11a/11b/11g/11na hostap
FreeBSD is 12.0-RELEASE

ifconfig does not le me change media in any way
but what i have noticed is that there is no definition inside regdomain.xml for 11ac

the last netband mode is <netband mode="11na"> there is no 11ac or V(HT80), V(HT160) defined i also checked https://github.com/freebsd/freebsd/blob/release/12.0.0/sys/net80211/ieee80211.h and there is information about it starting from line 745 * 802.11ac definitions - 802.11ac-2013 .
so i don't understand if there is still no support for 802.11ac even if we have working driver or it's a driver problem or missing regdomain ..?

ifconfig: SIOCSIFMEDIA (media): Device not configured

FreeBSD is 12-CURRENT

12-CURRENT doesn't exist any more since 12.0-RELEASE (12.0-STABLE actually). Update to the full -RELEASE version. If you are running -CURRENT it's 13-CURRENT now and that's an unsupported development version.

Topics about unsupported FreeBSD versions

Edit: Post appears to be edited now. Which is fine, but can you post the output of uname -a? I'd like to verify the version.

 

[kiokoman]

sorry, it was only a typo
uname -a
FreeBSD freebsd64 12.0-RELEASE FreeBSD 12.0-RELEASE GENERIC amd64

 

[aht0]

are you using wpa_supplicant from base or ports?
security/wpa_supplicant seems to have AC support unticked by default. Maybe (just speculating) you'd have to recompile the package from ports? One step closer at least.

Another thing I'd try is to try forcing WiFi mode through /etc/rc.conf

Also found https://wiki.freebsd.org/WiFi/80211ac but it seems to be over a year old.

 

[kiokoman]

no i'm configuring it with ifconfig and hostapd, its mode is hostap so i'm using it as an access point not as a client

ifconfig athp0_wlan0 mode 11na
ifconfig athp0_wlan0 channel 56:ht/40-
hostapd -B -P hostapd_athp0_wlan0.conf

content of hostapd_athp0_wlan0.conf
interface=athp0_wlan0
logger_syslog=-1
logger_syslog_level=0
ctrl_interface=/var/run/hostapd_wlan0
ctrl_interface_group=wheel
ssid=wifi-5G
debug=
beacon_int=100
dtim_period=2
max_num_sta=255

fragm_threshold=2346

wpa_pairwise=CCMP
rsn_pairwise=CCMP
wpa_group_rekey=3600
wpa_strict_rekey=
wpa_passphrase=mywifipasswordhere

this is how it's working now
if i try to force the mode -> ifconfig: SIOCSIFMEDIA (media): Device not configured

The FreeBSD wireless mailing list may be of more help.

According to this wiki page: https://wiki.freebsd.org/WiFi
(last updated 2018-07-21)
FreeBSD doesn't have support for 802.11.ac yet.

 

[scottro]

It *will* see cards that use 802.11ac--for example, I have a couple of multiboot machines with Intel wireless cards that can do either, and it will join the 5GHz network without problem. However, it will not give 802.11ac speeds, giving about 2-12 (only got 12 once though, 2 or 3 is more common) where a Linux install on the same machine gave me 30-40 MBs (and that is a capital B, this was on a LAN).

 

[rootbert]

uh ... this sounds sad, maybe I have to rethink my plan about going with freebsd on my notebook

Just go with Linux. Linux is a better choice for battery based device.

 

[k.jacker]

Linux is a better choice for battery based device.

That's simply not true. Especially without context.

 

[badbrain]

That's simply not true. Especially without context.

That is very true. Battery life: Windows > Linux > BSD.
Network speed: Linux > Windows > BSD.
It's the observation of my plain eyes, though.

 

[Crivens]

Sorry pal, but the plural of anecdote is anecdoteS, not fact or data. Measurements are in order here.

 

[Abhi]

It is said that the current 12.2 support 802.11ac.... then how it is configured.....as I am using Qualcomm Athero.... WiFi....??????

 

[scottro]

For what it's worth--I have a CURRENT install on a laptop, and network speed (on LAN) is still around 2-5Mb as opposed to 20-30 on Linux. As Crivens points out, that is just anecdotal evidence, but it's been quite consistent for me with Intel wireless cards and FreeBSD, on 3 laptops, a yoga2, an old Thinkpad (L420, I think), and a generic clevo barebones, all with Intel 7260. Never paid that much attention to battery life because usually, I use them at a desk where I can easily plug the machine into a socket.

 

[Yaazkal]

As far as I understand 802.11ac is still not supported. The recent 12.2-RELEASE wifi notes are: "Merge WiFi net80211, drivers, and management in order to support better 11n and upcoming 11ac."

upcoming 11ac

source: https://svnweb.freebsd.org/base?view=revision&revision=365670

You can try anyway to upgrade to FreeBSD 12.2 and see what happens with those changes as the ath driver is the one with updates.

 

[phalange]

As far as I understand 802.11ac is still not supported.

This is true, I think this update just contains the groundwork for future improvements. I tested 12.2 but my driver iwm() is still stuck at 11g.

 

[JonaEngel]

I am running 12-STABLE on a t470p and get higher anecdotal speeds with security/wpa_supplicant than with wpa_supplicant form base. I do appreciate this.

 

[Yaazkal]

I am running 12-STABLE on a t470p and get higher anecdotal speeds with security/wpa_supplicant than with wpa_supplicant form base. I do appreciate this.

Let me ask... isn't almost the same? I mean... wpa_supplicant from base comes from http://w1.fi and also the one from ports... wpa_supplicant from base is version 2.9 and from ports says 2.9_7... that version difference does make a significant optimization? Also, how wpa_supplicant can helps on speed, isn't it the job of the driver? (asks because I don't know).

I do appreciate the clarifications.

 

[phalange]

I am running 12-STABLE on a t470p and get higher anecdotal speeds with security/wpa_supplicant than with wpa_supplicant form base. I do appreciate this.

I think it would be good to substantiate this with easily obtained data on your up/down speeds. Don't forget to post your ISP's theoretical limits too.

 

[ScopeDog]

Well, I may be understanding this thread wrongly but installing /usr/ports/security/wpa_supplicant with IEEE80211AC on and adding mode 11a to ifconfig_wlan0 in /etc/rc.conf like
ifconfig_wlan0="mode 11a WPA SYNCDHCP"
works for my Intel AC9560 chip.

802.11a is not the same thing as 802.11ac. The latter provides 20 times the bandwidth. Your card is supported, but its ac features are not. That's why you're limited to 54 Mbps.

Oh, OK. Thanks.
