Wireless on SG-2440

dennypage

I've sent several in via the gui (and then deleted them).

My last crash was caused by simply changing the WPA PSK. :)

I saved the entire dump if you would care to have a look, but the most pertinent sections are:

Hmm, interesting. Certainly looks at first glance to be some driver issue though it works flawlessly in the APU.
Are you able to try both miniPCIe slots?

Steve

I'm a bit reluctant to open it up until I talk with the pfSense store folk.

I just had to do the install on Easter weekend… :)

stephenw10

Ah, OK it came with the card installed already?

These things are so new you guys have them before we do. ;)

@stephenw10:

Correct.

dennypage

Okay, after a few dozen more tests…

I've learned that to get consistent results, I need to make the changes in the interface, halt the system, and remove the power cord for a few seconds.

Here is where I am at as a baseline:

Persist common settings off
Standard 802.11ng
Protection mode off
Channel 11b/g/n
Transmit antennas auto and auto
Regulatory domain FCC
Country United States (US, FCC)
Location indoor
Mode Access Point
SSID Test
Minimum wireless standard Any
Enable WME on
Enable WEP off
Enable WPA off

With this configuration, the system will boot. The Status->Wireless page will show several other APs within reach. Based on this, I assume that the PCIe connection is functional.

The AP Test does not show up as advertised on the wifi scanner. Nor can it be joined.

If I change the mode to Ad-hoc without removing the SSID, the system will crash on boot.
If I change the mode to Ad-hoc but change the SSID to blank, the system will boot.

doktornotor

Did you try to run some Linux on it to check whether the wifi works at all?

dennypage

@doktornotor:

I'm not sure I understand the question.

Are you asking if I've installed Linux on the pfSense hardware as a test? If so, then no I haven't.

doktornotor

Yeah… that's exactly what I'm asking.

Guest

Just for testing have you tried creating an Access Point without WPA or WPA2, just to eliminate WPA supplicant as a culprit?

Also under System Logs>>Wireless what does it show??

stephenw10

You will need to have WPA enabled to create an AP with 'ng' mode selected as I understand it.

@Phishfry:

Yes, in G mode.

Guest

What about the Wireless>>System Logs, anything these usable for hostapd diagnosing?

dennypage

@Phishfry:

Nope, just rekey messages.

Guest

Just for the record, WPA/2 is not required for AP mode, in G or NG/NA mode. I just tested to ensure nothing changed. I know some field verification was added for ease of setup in wireless.
In fact WAP is not checked by default.

doktornotor

For N, you need either WPA2 or no authentication whatsoever. WEP/WPA not supported.

Guest

Well I may not have been much help but i had to ask some of those basic questions..
Good luck, i am sure the support crew will get you going in no time.

stephenw10

Yeah, even if you choose wpa or both if you check the encryption used it's wpa2.

At a minimum, it would appear that pfSense isn't invoking ifconfig correctly:

Even with a standard of 11na and channel 36 specified in the config, ifconfig ath0_wlan0 reports

media: IEEE 802.11 Wireless Ethernet autoselect mode 11b <hostap>An explicit call to ifconfig specifying channel 36 will result in

media: IEEE 802.11 Wireless Ethernet autoselect mode 11na <hostap></hostap></hostap>

dennypage

My current config if it helps:
