Unable to set wlan8 channel to 165

james_leonard — Tue, 10 Sep 2013 10:24:21 GMT

Hi there,

I just setup my Zoneflex 7982 and noticed some repeating errors in the log file.

5ghz Radio:
Wireless mode: 5ghz
Channel: SmartSelect
Channel Width: 40mhz
Country Code: New Zealand

Running software version: 9.6.0.0.267

In the log file:

I rebooted the AP, prior to the reboot it was doing it for channel 116, after the reboot its doing it for channel 165.

Any insight would be appreciated

Cheers,

I think it's related to channel bonding for the 40Mhz width combined with your country code. Try going to 20Mhz and see what happens.

Re: Unable to set wlan8 channel to 165

james_leonard — Tue, 10 Sep 2013 20:00:27 GMT

When I go with 20Mhz, smartselect starts off on the lower channels then jumps up to 108+ within a few minutes. There's no other 5ghz AP's around me and it seems to detect interference a lot, this normal?

It seems my MBP 2010 doesn't support some of the channels its selecting:

Card Type: AirPort Extreme (0x14E4, 0x8D)
Firmware Version: Broadcom BCM43xx 1.0 (5.106.98.100.17)
MAC Address: 78:ca:39:b0:f1:16
Locale: APAC
Supported PHY Modes: 802.11 a/b/g/n
Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165

However my Mac Mini supports all the channels:
Locale: APAC
Country Code: NZ
Supported PHY Modes: 802.11 a/b/g/n
Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165

The above aside, I would prefer to use 40mhz, is this a bug in the firmware with the New Zealand region?

With just the Mac Mini going:

Possibly, so I've opened a case for you.

james_leonard — Wed, 11 Sep 2013 04:34:11 GMT

Hi Keith,

Much appreciated.

I changed the country to Australia out of interest, same deal. Suspect it'll affect anyone in the same region that Australia and NZ are in

Cheers,
James

Re: Unable to set wlan8 channel to 165

keith_redfield — Tue, 17 Sep 2013 19:17:52 GMT

Just to close off, I think we've opened a bug on this. Your workaround is to blacklist the channels that are impacted.

Re: Unable to set wlan8 channel to 165

peter_dohm — Mon, 07 Oct 2013 03:23:42 GMT

fyi, i've also had this happen on a 7982 with the same firmware release, configured with all defaults (except that i enabled the 2.4 and 5ghz radios and gave them SSIDs)...

Re: Unable to set wlan8 channel to 165

This reply was created from a merged topic originally titled
anyone else see this error message on 7982 standalone running 9.6.1.0.15?.

hi all.

has anyone else seen anything like the following in their syslog output on a 7982 running 9.6.1.0.15? mine's running in standalone mode and has smartselect enabled, but i'm unsure if either of these factors matters or not...

Oct 7 02:39:51 ap daemon.info channel-wifi1: channel 165 now UNBLOCKED

Oct 7 02:39:51 ap user.warn kernel: findchannel:830 Couldn't find matching channel for chan(165) flags(0X80100)

FYI, channel 165 is not blacklisted, so i'm a bit unsure whether this is just a superfluous informational message, or not...

this error message will be produced every 30 seconds or so, and never seems to resolve itself...

Re: Unable to set wlan8 channel to 165

I too have Software Version: 9.6.1.0.15
I've been pulling my hair out with these errors and it seems I'm not alone here. I just installed two 7982's and clients can't maintain a connection. The log is flooded with the following:

Also sporadically seeing variations of the following:

I'm really hoping there's a quick fix for this... as of now I have two very expensive paper weights.

Re: Unable to set wlan8 channel to 165

keith_redfield — Tue, 08 Oct 2013 19:59:18 GMT

@Daniel - are you also using 40Mhz channels? Try switching to 20Mhz and see if that changes the behavior.

The latter log messages you are seeing are normal ChannelFly messages.

Re: Unable to set wlan8 channel to 165

daniel_coker — Tue, 08 Oct 2013 22:06:13 GMT

I went ahead and made the switch to 20Mhz channels on both AP's. (Note that it was already using 20Mhz on the 2.4G radio so only had to switch the 5G). Since then the UNBLOCKED entries have gone away. Here is the last ten minutes of log activity. It still seems like there is a lot of unwanted activity but perhaps you can make sense of it. The "unable to find active wlan device" concerns me the most. Also, no matter what time server I use, the time stamps are about 7 hours off.

Re: Unable to set wlan8 channel to 165

OK, I've noticed this too. Just to recap.

The workaround is to switch to 20MHz on 5GHz?
Does this apply to all or some country codes?
If I go back to 9.5 FW, will it work?
Is it on standalone APs or ZD controlled, or doesn't matter?

How can I blacklist 165 on standalone AP?

If you don't want to switch to 20mhz then you can just blacklist the offending channels, for me there was about 3 of them

Just ssh into your AP and run:
set blacklist wifi1 xxx -1

Where xxx = channel number

My AP is standalone, not sure it matters

James, I was doing exactly that, but the issue just kept surfacing on different channels that I had to blacklist, one by one. I finally gave up and used 20 Mhz bandwidth instead...

Merry Xmas all,

Thought I'd let you know that Ruckus have fixed the bug in releases 9.6.2.0.13 and 9.7.0.0.220 which are available for download here https://support.ruckuswireless.com/so...

I'm using 9.7.0.0.220 as I'm only using a standalone 7982

Cheers,
James
