Atheros Chipset Issues

  • Well as recommended I am using the latest snapshot…. "pfSense-20080729-0437.iso.gz 29-Jul-2008 01:32 40M" and still the disconnect issue remains....

    hostapd: ath0: STA 00:1d:4f:27:62:09 IEEE 802.11: deauthenticated due to local deauth request

    Is there a plan for a fix on this issue?


  • It looks like this has been an issue in various cases long before 1.2.1. I've never personally seen it, if you can provide specific information on how to replicate and I can replicate it, we might be able to report it to one of the FreeBSD lists and get a resolution.

  • After I fire up my iTouch Instantly I see this in my logs…

    Thank you for your reply and attention to this matter!

  • By the way the card specs…

    802.11a/b/g WLM54SAG mPCI
    Witha a ALIX 2c3 Board.

  • The iPhone and iPod Touch must use TKIP with WPA, you probably just have a configuration they aren't compatible with. I'm not sure why it is that they won't work unless you set it to TKIP, but that's what I do and what others have reported on here.

    This also is the case with AirTunes, though my Mac mini G4 will connect regardless of that setting.

  • I would like to add Dell's wireless print server 3300 to this list.  I had to set pfSense to use TKIP only.  If I tried to set the option to both AES and TKIP(option "Both") I would get that error.

    Edit:  I had to edit my post it initially stated "the option to both WPA and TKIP(option "Both")".  Sorry for any mix up.

  • Thank You for all the reply's…

    Here are the settings I have been using...

    General configuration
    Type - Static

    Bridge with - none
    IP Address -

    Standard - 802.11g

    Mode - Access Point

    802.11g OFDM Protectione Mode - Protection Mode RTS and CTS

    802.11g only - Is checked.

    Transmit Power - 70mW - It seems that at this range I get better reception and less disconnects...

    Channel - 11g Turbo - 6  - Also is the most stable channel I can get any thing else I use it grabs the wireless and makes it more unstable.

    WPA - Enable

    WPA Mode - WPA

    WPA Key Management Mode - Pre Shared Key

    Authentication - Open System Authentication

    WPA Pairwise - TKIP

    Key Rotation - 60

    Master Key Regeneration - 3600

    Any suggestions to make my system  more stable? I have been using TKIP since day one...

    I have 2 iTouch one is running Firmware v 2.0 and the other 1.1.4 or something around that range... But both seem to experience the same disconnect issue the 1.1 more than tha 2.0

    Thank You all for your attention.

  • my iphone 3g connects to ddwrt ap with wpa2/aes just fine

  • @covex:

    my iphone 3g connects to ddwrt ap with wpa2/aes just fine

    DD-WRT is Linux… Where pfSense is FreeBSD.

  • I know, what I meant is that it works with ads too not just tkip

  • In FreeBSD 7.0 based releases, I no longer have to force TKIP for my iPod Touch and AirTunes to work properly, they work fine on Any now.

  • Is this on the latest Update?
