In/Out errors :(

GoldServe

I'm curious, change your rxbug and txbuf to 2000 instead of 40 and 100 by default.

sysctl hw.ath

hw.ath.hal.version: 0.9.17.2
hw.ath.hal.dma_brt: 2
hw.ath.hal.sw_brt: 10
hw.ath.hal.swba_backoff: 0
hw.ath.dwell: 200
hw.ath.calibrate: 30
hw.ath.outdoor: 1
hw.ath.xchanmode: 1
hw.ath.countrycode: 0
hw.ath.regdomain: 0
hw.ath.rxbuf: 4000
hw.ath.txbuf: 4000

neonsigns

I try that tonight. Will let you know the results. Thanks

neonsigns

Hey GoldServe

How do I change the values? When I do sysctl hw.ath.txbuf=2000 it says

sysctl: oid 'hw.ath.txbuf' is read only

Same for the rxbuf

neonsigns

Thanks GoldServe

I added "hw.ath.txbuf=3000" and "hw.ath.rxbuf=6000" on loader.conf and almost no In/Out Errors. And the WiFi is rock solid. Thanks again.

Eh?? Please test for a while and report back. This is very interesting.

@sullrich:

Wifi is still working solid. No random disconnections.

In the last 24 hours I have only 180740/0 In/Out errors. Before the change, this number was at least 10 times larger.

Lets see if this works permanently.

neonsigns

The errors are creeping up again. Here is the latest athstat with rxbuf and txbuf at 3000 and 6000 respectively

Any suggestions? Also, the dev.ath.0.rxantenna keeps switching from 1 to 2 and back?

neonsigns, could you post your config file (sysctl)… or at least a section of it with wifi settings you did
i tried g and a, different settings from this thread and still getting tons of in/out errors (btw, "a" mode produces less of'em :-)

can you please try by forcing the media manually?

I have read somewhere that in freebsd, you can disable te bgscan via ifconfig ath0 -bgscan but it's not available in 6.2. Maybe someone can port over 6.3 and see if this helps.

I've the same problem about tons of IN/OUT errors. I also have a wifi card based on Atheros 5212.
I've been trying pfSense with the new txbuf and rxbuf and disconnections happen 8-9 hours later the first association instead of every 2 hours as usually occurs without that change in /boot/loader.conf
In my case those parameters in loader.conf make less OUT errors and few IN errors, but unluckily it doesn't solve the problem. Disconnections shouldn't occur due to the short distance between pfSense wifi antenna and client one.
It has been a year wifi connection have disconnection every 2-3 hours :(
As I've said, today wifi connection lasted 9 hours and then disconnection. I bet it will get disconnected with 9 hours from now.
I tought about a problem with hostapd, but now I think that is more driver related.
Moreover, I've two configurations and all of them have wifi cards based on Atheros chipset from different producers: I have the same problem reported in this thread with them. :-\

What can we do? My wifi cards aren't faulty and I think yours, too. How can we report this problem to the maintainer of FreeBSD wireless drivers? Developers, we need your help! ::)

Hi neonsigns and all,your /boot/loader.conf looks like this ?

autoboot_delay="1"
kern.ipc.nmbclusters="0"
"hw.ath.rxbuf=6000"
"hw.ath.txbuf=3000"

firestar

@werneman:

Not exactly. Be aware with system files!

autoboot_delay="1"
kern.ipc.nmbclusters="0"
hw.ath.rxbuf="6000"
hw.ath.txbuf="3000"

…or without "

covex

hey guys!
why would i have my in errors skyrocketing and our errors stay at the same level?
see attach…
tnx

@ermal:

ermal, how do I do that?

My loader.conf does not have kern.ipc.nmbclusters="0". What does this setting do?

lsf

[20070116, update 20070212] Systems with very heavy network activity have been observed to have some problems with the kernel memory allocator. Symptoms are processes that get stuck in zonelimit state, or system livelocks. One partial workaround for this problem is to add the following line to /boot/loader.conf and reboot:

kern.ipc.nmbclusters="0"

Setting this to 0 removes the max limit on allocating nmbclusters, this can be a problem if you have very large amounts of connections and not a lot of memory, So use it with caution.

neonsigns

I set the media to OFDM/54Mbps 11g and the kern.ipc.nmbclusters="32768" but I am still getting "In" errors and random disconnections.

firestar

@neonsigns:

but I am still getting "In" errors and random disconnections.

Same problem. Is it ok for a wireless interface?
How does pfSense get those data (in/out errors displayed in Status-Interfaces)? What is the equivalent command from the shell?

Thanks

Don't know what is causing the errors. Athstats shows that the two biggest errors are:

"rx failed 'cuz of FIFO overrun" and "beacon setup failed 'cuz no mbuf"

Anyone have any insights?
