Wireless on SG-2440

[Guest]

How about from your WebGUI under Status
Checkout >>Interfaces>>Your Wfi Interface
See if you have blockage or packets flowing

Also under Status on the WebGUI checkout Wireless. This gives you some more info,

I am attaching my setup to compare.


[dennypage]

The SSID doesn't appear, so there are no associations. Just one outbound packet:

Status up
MTU 1500
Media autoselect mode 11na <hostap>Channel 48
SSID Test
In/out packets 0/1 (0 bytes/96 bytes)
In/out packets (pass) 0/1 (0 bytes/96 bytes)
In/out packets (block) 0/0 (0 bytes/0 bytes)
In/out errors 0/1
Collisions 0</hostap>

Hmm, I've not tried those two pieces of hardware (yet!) but I have one running great in the APU.
Some things I found were:
To run any sort of 'N' mode you must have WME enabled, be using WPA and select a valid region. You look to have done that.
If you select a channel that isn't valid in your selected region you will get nothing, like you're seeing.
I never got NA mode to work but I don't have any 'A' devices to test with.
Do you have any crash reports?

Steve

[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

[dennypage]

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.  ;)

Steve

[dennypage]

@stephenw10:

Ah, OK it came with the card installed already?

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.
