Lol yeah but that was what I meant ... if some is interested in coding it
... are you for example?
Judging for the amount of work you have with ath etc I guess not, and I got
a feeling this would be "fun" to do :)

I can't really take that on right now personally, but what I can
suggest is that you contact the FreeBSD foundation and let them know
that you'd like to see improved wireless and you're willing to donate
/ fund the work.

Here's additional place where FreeBSD has lack of support: USB based printer=
s.
Here's a citation from the FreeBSD handbook (page no. 251):
> USB interfaces, named for the Universal Serial Bus, can run at even faster=
speeds than parallel or RS-232 serial interfaces. Cables are simple and che=
ap. USB is superior to RS-232 Serial and to Parallel for printing, but it is=
not as well supported under UNIX systems. A way to avoid this problem is to=
purchase a printer that has both a USB interface and a Parallel interface, a=
s many printers do.

Why don't you try citing a non-ancient version the handbook? Like here:
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/printing-connections.html
which states exactly the opposite. And USB printing has worked quite well
for a long long time on FreeBSD.

That appears to be an old version of the Handbook. The current printing
chapter covers all four common connection types:

Since (new|more) talent in the 80211++ space is evidently needed,
I would suggest trying a bounty. Maybe $5K? That's a lot
of money in many places in the world. (Adrian has done
tremendous work, but what about die bus? It happens to
all of us, eventually.)
I'm a wired-by-default guy, with a house full of CAT5, but the
future is wireless.

I guess the problem is not the money but finding someone who actually
knows what to do.

The problem -is- the money. The people will come when there's enough
interest and enough money.
The problem is that people think things like wifi drivers that are
debugged, perform well and get updated as new standards appear is a
few months effort - and I think the herculean efforts done in the past
by people like Sam fuel this myth.
I've spent almost two years of weekends and evenings hacking on
net80211 and the atheros driver to get it to where it is. The 11n
support for atheros chips appeared when someone (hi Hobnob!) paid me
for six months to get 11n done. I'm still debugging weird corner cases
with rate control and congestion handling even now. And this is _on
top_ of all the work done by the Atheros team to write the HAL in the
first place.
I've spent almost 18 months of weekends/evenings hacking on the intel
iwn driver to find all the little odd corner cases that make it
unusable by a lot of people. I keep saying I'm not, but since the
laptops I'm using have iwn in them, I end up getting annoyed enough to
fix it. This has all been for free.
Wireless stuff is a very complicated, very time consuming thing that's
immensely fun if you're into this kind of thing. But please understand
- it's a huge time commitment for each individual device and new
standard.
So yes, it's the money. I've jokingly said that it's $100k and 2 years
for me in (evenings, weekends) time and equipment to port and debug
one driver for a given NIC. Not just do a "oh look here's an openbsd
driver ported from linux in a month" port - that's just the beginning
(and I tend to quote something like $10k for that) - I mean, something
that ends up implementing the updated standards (11n, 11ac soon);
something that includes powersave, something that includes debugging,
something that handles a multitude of bad environments that people see
every day and complain about. Ie - the level of work that makes it "oh
it just works, I can get on with work now" level of work.
I don't want to let myself be dragged into another two years of
weekends. I kind of need some sleep here and there.

Hi there!
I've a ZTE USB modem and I want to use it with FreeBSD. I've attached it to o=
ne of the USB slots on my PC and run the "ls -lh /dev/" command to see what'=
s going on. I've saw that two modem devices have been created in the 'dialup=
' group: cuau0 and cuau1.
My question is why were two devices nodes created instead of one and how sho=
uld I know which of them I need to use?
Regards,
Atar.=

Typically, they will show up as /dev/cuaUx or /dev/cuaUx.x (note the
capital U). Make sure you have the u3g driver loaded as well. (kldload
u3g). Also, some ZTE sticks need to be put in "modem mode". This can
often be done by sending the eject command to its "cdrom"
if its listed as pass0, try the command
camcontrol eject pass0

Thanks you for your kind support.

That's interesting since in the output of 'ls -lh /dev' in my PC it appears w=
ith no capital 'U'.
In addition, I've tried to initialize the both devices with 'ppp' but when I=
tried to enter the 'term' command, ppp hangs up and don't give me an option=
to send to the modem commands. Any idea what's the problem?

Hi All!
After I backported all of the net80211 and iwn changes from 11-CURRENT
to 10-STABLE the wireless NIC in subject working on mode G. If I try
to use with mode N (ht20, ht40) it failed in association state.
All of the backports are in this github repo:
https://github.com/opntr/opBSD/commits/op/stable/10-iwn-backport

Cool! Have you tried freebsd-head? Does it work there?
How's it failing in association state? What's it saying?

I not tried freebsd-head yet, but I'm able today. In mode N seems like
the NIC sends only one frame, and no more.
With tcpdump and/or wlandebug I see only rx packets and no tx.
If you add some pointer what changes must I create to easier debug, or
what concrete information required, feel free to ping me or send the
details.

Thats your onboard serial ports (uart0 and uart1).

Did you load the driver (kldload u3g) ?
what is the output of
usbconfig
it should show something like
# usbconfig

Thanks for doing this detailed analysis of various issues. Whenever
possible, please submit manpage update fixes via bugzilla. And I'll work
with you to get them reviewed/committed.
> Long story short; FreeBSD's wireless support is lacking. It's almost a
complete mess. It takes many time and frustration for a user to get a
working product that works decently with FreeBSD. And even then, it often
works without features like 11n and proper power save features. It's one of
the areas that FreeBSD is much behind in terms of hardware support compared
to virtually every other operating system out there. That's a shame;
FreeBSD would be an excellent wireless access point when paired with
pf-firewall.

Yes. It needs a lot of love (work).

wireless products. Each product should note which chipset it uses, what
driver it connects to, what features are suported (i.e. HOSTAP), what
FreeBSD versions are supported, whether it is open source / binary blob,
any license requirements (like Realtek) and a dmesg snippet where the
driver is detected. It can be managed by a maintainer that accepts email
reports from users who provide the required information. That way, we get a
list of hardware that is known to work with FreeBSD that people can
actually buy. Even a NewEgg-link or something to that effect can be
provided.

needed very badly, to prevent other people from going through the same

this list would be very helpful i would presume.

Yes. I like this idea. But more important thing is who is willing to drive
this? If you are, I'll have you setup with a wiki account :)
Thanks again for your interest and such diligence.

Hi!
Small status update:
The mode N works too, I mistyped the other AP's passwork.
So both mode G and mode N working after the backports.
BTW, can you MFC the same changes to 10.1?

Thanks for this, and for all your work, Adrian. Let the M$ troll in
questions@ crow that ew're not keeping up with his multi$Bn corp ..
Volunteerism has its limits, and noone can meet the illspecified and
neverending demands for more. Get some sleep here and there, short of
starving. Someone whinging 'when are you coming to bed?' helps :)

I fully agree with that we need more structured documentation about what
is working, in which versions and with which details. I'm editing in the
FreeBSD Wiki the webcam compatibility list and I know that editing Wiki
pages can be a mess and is not what every user who got something to
work, or to know, is wanting to do. What we do need is somekind of
database with a webform by which everybody could insert (or even edit)
exsisting data, ofc with somekind of creation of account and an anti-SPAM
capcha. Without this, the data actualization depends on the time and
availibility of the maintainer(s) of the page and information tends to be
outdated.

Maybe it would easier to maintain a list of supported chipsets and
provide a link to a website with a hardware database (e.g.
wikidevi.com)? There are not so many chips as compared with the amount
of different devices. Also wikidevi and similar projects are not
depend on OS and have a wider auditory. Just my 2 cents.

Workaround - reboot AP system :-(
Thank you!

Hi!
When this happens, can things re-associate?
Can yuo do this:
sysctl dev.ath.0.txagg=1
(and dev.ath.1, dev.ath.2, etc if you have more than one physical
atheros NIC in your AP) and paste the results?

Hello Adrian,
Yes, this always appear. In chronological order, this can be described as
follows:
1. system reboot
2. for several hours, all clients can successfully associate and works fast
3. transfer rate is reduced and there are increasing messages:
ath0: stuck beacon; resetting (bmiss count 4)
ath0: stuck beacon; resetting (bmiss count 4)
ath0: stuck beacon; resetting (bmiss count 4)
ar5416StopDmaReceive: dma failed to stop in 10ms
AR_CR=0x00000024
AR_DIAG_SW=0x42000020
ath0: stuck beacon; resetting (bmiss count 4)
ath0: stuck beacon; resetting (bmiss count 4)
ath0: stuck beacon; resetting (bmiss count 4)
4. finally connections are interrupted and customers can no longer be
associated
I use TP-LINK TL-WN851ND v1:

--- Comment #1 from Adrian Chadd <adrian@freebsd.org> ---
I think that calibration hang means the baseband has gone RX deaf.
I wonder if a full chip reset will fix it, rather than a warm chip reset. I'll
have to go experiment.
