2.2BETA: Atheros ar9227 extremely unstable wifi, plus N mode does not work.

rjcrowder

I've now tried three pci-e cards under 2.2 with poor luck all the way around… Intel does not work in hostap mode and atheros seems to only work in 'g' mode. Even if the interface comes up and says b/g/n, it only functions at 'g' speed.

The cards I've tried:
Atheros 9287 - Only works in 'g' mode as you described. Must manually pick a channel.
Atheros 9285 - Same as above
Intel 5110 - Does not work in hostap mode.

That Intel card doesn't support hostap mode in the hardware, that's nothing to do with software.

The Atheros n cards, yeah something going on there with n.

Any idea what the ath_chan_set warnings are? I'm having some issues there as well. Here's my "ifconfig ath0_wlan0" output:

Try setting the regulatory settings. Mine was defaulting to DEBUG and when I connected it was showing g speeds. I set it to FCC, USA. indoor and the connection now shows 135.
Technical details for those not following the other thread:
APU with 9285/AR5B95 running 2.2B
Interface is configured as an AP, WPA2, AES, standard set to ng, nonly.
Note this is a test box, not connected to the Internet. I am basing connection speeds on what a Windows laptop tells me when I connect to the AP. No throughput tests were done.

My regulatory settings are on FCC without a difference. I tried your other settings and it still isn't working. Would you mind posting your configuration? Thanks!
If there's any more information you'd like me to provide, just mention it.

Sure enough. Exact same thing here after further testing. Now set the same as yours, and I was associated at 135. Though now it's having issues in general, and I'm short on time for now. Will have to revisit later.

Experiences of others would be appreciated.

I haven't seen that in particular, though Googling it finds people with the same on FreeBSD. I only briefly reviewed the results, didn't see an answer anywhere, but it's worth searching on to see what you can find.

My best guess, from experiences in earlier releases (though current wifi is vastly diff) is maybe try setting the channel differently. Don't put it on auto, try setting something specific. If it's already set to something specific, try a diff channel.

Does anyone here think that it might have something to do with the 5GHz band of these cards? This issue is becoming really annoying as it's preventing me from using n wifi…

dotdash

They have no 5Ghz band. 9287/9227 is 2.4 only. The message where it returns values for 2GHz and 5GHz radios is confusing.

I'm not using AR9227 but a card with AR9380 and I cant get N to work either. Tried to set Regdomain to FCC, USA and indoors but still only 54M.

Same here… can't seem to get "N" speed on any settings...

How do you have the channel configured? Seems for at least one person I talked to, it did that until they changed the channel from auto to something specific.

Manually setting the channel gets "G" working… but haven't found anything that solves the problem of getting to "N" speed...

Internal chuckle... reminds me of a quote from spaceballs, surely this must be the issue... "we are approaching ludicrous speed".

@cmb:

I have tried both NG and NA with channels 6 and 60. Auto does not work at all, interface is down if I choose auto.

I get the same as "rjcrowder", setting channels manually gets G speeds working, but no N speeds.

On a side note: Spaceballs is awesome!

Is there any chances to get working Ralink rt3072 on 2.2? I have USB edup ep-ms1532 with this chipset, but I have no luck with pfsense. It's shown and can be configured as interface once untill I apply settings… pfsense beginning to reboot itself with kernel panic.
Other question is... DO you have any plans to get a new interface for wifi settings, where we can see N mode also and other settings related to new wifi standarts? ???

I set up an SSID and it doesn't appear visible to any client. Even when I tell the client the name of the SSID, as though it was a hidden broadcast then its still not found.

In GUI -> Interfaces -> "Wireless" -> "Common wireless configuration - Settings apply to all wireless networks on ath0." I set the Standard to 802.11g and it works fine.

I can set the Standard to 802.11a and it also works, but I only have one A mode radio device.

Can you double check if the interface comes up when you set it to "N" mode (on the interface status page - or just look at interfaces on the dashboard). For both Atheros devices I've tried, the interface will not start if I put it in "N" mode - hence no SSID showing…

gregober

I was testing quite extensively the Atheros 9280 using the same HW as CMB.

Whatever the settings, I have many "ath0: stuck beacon; resetting (bmiss count 8)". I have updated the hw tunable settings with no luck.
It is more stable using G but quality is all in all very bad and unstable.

When you start using bridge mode, It become close from unusable, whatever the settings.

I have ping with time ranging from 10ms up to 1600ms… when It can ping.

GruensFroeschli

I have been playing a bit with the beta.
My impression is, that it's a lot less stable than the alpha builds i tested.
However i havent had the time to dig in to debug.
Regarding getting n to work:
What probably most people are missing, is that n requires QoS.
Ticking the WME checkbox will maybe help.
