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,
James

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.

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.

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
