Atheros Chipset Issues

cmb

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…

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…
@cmb:

Here are the settings I have been using...

General configuration
Type - Static

Bridge with - none
IP Address - 10.30.2.1/24

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:

DD-WRT is Linux… Where pfSense is FreeBSD.

covex

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

cmb

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?
