iwn0/wlan0 scan WPA2-PSK/AES as WEP on freebsd9

[乔楚/HonestQiao]

I have a lenovo thinkpad x201i which os is FreeBSD9.1-prerelease/amd64.
Its wireless card is Intel Wireless N-1000, and driver is iwn/iwnfw.

And I have an home wireless route which is TP-LINK TL-WR843N.
When I set WR843N as WPA2-PSK/AES mode, my BSD can't connect to it.
Set: 2.4G / 11bgn mixed / 40MHz / chl:11 / 300Mbps
#ifconfig wlan0 down
#ifconfig wlan0 up scan
#ifconfig wlan0 list scan
It will list WR843N as a WEP AP, so it cant connect to AP.
But other laptor which os is windows7 can connect to AP correct.
And My MobilePhone which os is android 4 can alao connect to AP.

When I set WR843N as WEP mode, my BSD can connect to it.
And I can connect to my company's WorkStation AP which mode is WPA2-PSK/AES.

Other info:
My BSD cant get right AP name of my WR843N.
The name of WR843N is 0x................
Other electronic devices can get it correct.

I also use the script named wifimgr in install iso of freebsd9, and use wifimgr in ports.
But the results obtained are identical.

Any one can tell me how to debug it, or force My BSD to correctly recognized WPA2-PSK/AES mode of WR843N?

Hi,

What's your /etc/wpa_supplicant.conf file look like?

And what's the output of 'ifconfig wlan0 list scan' look like?

That SSID looks very odd. And look at the output of wpa_supplicant -
it isn't finding any WPA enabled APs.

And do an "ifconfig -v wlan0 list scan" at home, to get the entire
SSID and decoded beacon contents from the scan cache.

Ok, I 'll test it at home. Now, My local time is 10:32 AM.

I also think the SSID is very odd. But other devices can get the right SSID.

RIght. It's quite possible that there's something about that beacon
frame format that's tripping up the beacon parsing code in net80211.

can you please take a snapshot using monitor mode?

tcpdump -ni wlan0 -y IEEE802_11_RADIO -s0 -l -v -w pcap.out

Run that whilst you're trying to associate, let's see what happens.

.. meshconf?

Are they setting some bit somewhere which is reserved for 802.11s, and
not setting up said 802.11s?

FWIW, you don't need to use -D bsd

Hi,

Also, take a look at the key setup:

RSN<v1 mc:AES-CCMP uc:AES-CCMP km:8021X-PSK>

it's an 802.1x PSK, not WPA-PSK.

What's the configuration of the openbsd AP? It's announcing 802.11n
IEs and it looks like it's all draft-era fields.

Can you disable 11n on openBSD?

My wifi router named OpenBSD support 11n only, 11 bgn mixed, 11 bg mixed, 11g only, 11b only.
I'll test for 11g only and 11b only.

Why it can be used in WEP encryption mode?
I only change the encryption mode between WEP and WPA2/PSK.

.. but does openbsd actually _support_ 802.11n? I didn't think it did.

My AP is TP-LINK TL-WR843N. I set OpenBSD as its SSID.
The official technical documentation says that it supports 802.11n.
I'll also test for 11n only.

Oh, ok. Right. Try 11g only. See if that works better.

There's something odd about that beacon frame that is tripping up
net80211. I'll dig a little deeper tomorow.

Thanks again,

OK, I'll make all the testings.

If you think it is necessary, we can determine a time-line communication and real-time test, in order to better find the problem.

You are right.
After several tests, I found the 802.11b 802.11g 802.11 bg mixed can use.
It can't connect to 802.11n AP.

My wifi card is Intel Centrino Wireless-N 1000 which support 802.11 b/g/n.
http://www.intel.com/p/en_US/support/highlights/wireless/n1000/

Is freebsd9/amd64 not support 802.11n ?
Or is the driver of my wifi card not support 802.11n?

No, FreeBSD-9 supports 802.11n on the Intel NICs just fine. I
currently have no idea why the 802.11n beacon IE is confusing FreeBSD.

Please file a PR with all the information you've gathered to date.

Thanks!
