[ath9k-devel] 3rd time lucky...

[Dmitri Seletski]

Hello boys and hopefully girls.

I was messing with card to get it somewhat working with N.
i got it working with n but in "limited mode", where only 54 meg speed
is possible(arm... i thought N and G are not exactly backward compatible
technology?). so i left ping running to AP over wireless(it was replying
without problems). left it like that, than decided to reconfigure to
full speed (300 meg)  ping stopped replying, whichis normal i suppose, i
decided to take a look into dmesg, whats going on, next moment computer
fully hangs.
well, i have dmesg on screen in hanged state, fair enough, take my
phone, and well, there are the photos of dmesg... Hope they  can be usefull.

I suppose i can set up cron to "dump" to my flash card dmesg information every second(if not mistaking its smallest value available to cron), if you want me to.

Check out screenshots.
Regards
Dmitri

P.S.
Was messing around with my wireless card and acess point.
I know it is working, but if you start to download anything with it or even "ping -A acesspoint" driver hangs and whole system goes down with it, disgracefully, without reboot or response. I am not a programmer, but looks like a memory leak and a dangerous one...

This should be fixed in the commit 6cc47a6f886f72d9d54a52aa656464feb2a99ba4
in wireless-testing.

Sujith,
Does this mean if I do a git-pull now I should get this?
Or is there some delay?

Also I have been doing git-pull's and recompiling wireless-testing.
Each compile takes some time(which I am happy to do) but is there a
quicker/better way?

Thanks,
Brian

You should get it, since the commit is in wireles-testing.

compat-wireless would be easier.

I got Already up-to-date so you must have updated a few days ago before
my last go.

The wireless link seems to be a lot more stable and I have not had a
lockup since.

However, I still have the problem where my router shows.

IP Address	Mode	Rate (Mbps)	Signal (%)
0.0.0.0		802.11g		130	62

Now I thought this might just have been a router issue so I upgraded my
firmware(glutton for punishment:). The update went well I am now at
firmware Version: 1.21
Hardware Version: A3
Product Page: DIR-655
(no-securespot version)

Again this seems to have improved things a lot.
But I am still left with the problem above.
Given that the wireless says it is set up for 11n

Wireless Enabled
802.11 Mode : Mixed 802.11n and 802.11g
Channel Width : 40MHz
Channel : 8
Secondary Channel : 4
WISH : Active
Wi-Fi Protected Setup : Enabled/Configured

I do not understand why it says 11g


Is there any way to show the actual MBs from the host side?
I am in the process of setting up iperf.

Thanks,
Brian

It means it will support stations that use either 11n or 11g.
If you have a station that supports 11n it will use 11n rates and
aggregation. If you use an 11g STA it will stick to 11g for
communication only with that STA.

New patch for nl80211/cfg80211/iw has support to see what last TX rate
was being used, even for 11n rates. Check the lists for that.

Sorry did not make myself clear.

This says the router will accept either
>> 802.11 Mode : Mixed 802.11n and 802.11g

This says my 11N pccard is connecting at 11G with a speed of 130?
>> 0.0.0.0         802.11g         130     62

Prior to rc7 it used to say 11N with a speed of 300.

will do.

This is obviously wrong as you cannot possibly usc MCS rates on 802.11g.
The mode of operation must be wrong here as detected by the AP. Contact
your AP support tech guys and bug them if this bothers you a lot, but
this is also minor.

> Prior to rc7 it used to say 11N with a speed of 300.

You mean a rate of 300Mbit/s, anyway you won't always use the 300
Mbit/s, the rate control algorithm will only use it when the conditions
are right for it. If you can determine the actual rate being used for TX
has changed and your environment is consistent and it *used* to use 300
Mbit/s successfully before then perhaps it is a bug and you can use
git bisect to determine the culprit commit.

I think I have a partial understanding of what is happening here.
The router is now displaying the MCS number.
I have my transmission rate set to auto,
My other options are MCS15-130(270), MCS14-117(243) etc.
The router is displays 130 or 117 usually.
So the only issue is why it displays the 11g but I am not worried about
that.

However, I will still use iperf to check what is actually going on.
