[arch-general] Master mode and Intel 4965AGN

[Adam Lloyd]

Hi, list,

I am trying to use my wireless card to share a wired connection.  I
have an Intel 4965AGN card, and I am fairly confident that this should
be possible; however, I've been unsuccessful after a few hours of
trying and Googling.

The issue seems to be that the card won't enter master mode.  Trying
to set it up manually with `iwconfig wlan0 mode master` results in
"SET failed on device wlan0 ; Invalid argument."  (As an interesting
side note, I can easily put it into ad-hoc, managed, or even monitor
mode this way.)

Using hostapd (with the nl80211 driver) fails with the message "Failed
to set interface wlan0 to master mode."

According to `iw phy0 info`, the supported interface modes are IBSS,
managed, and monitor.  I booted up an Ubuntu 9.04 live CD and compared
the output of `iw phy phy0 info` there, and indeed, AP and AP(VLAN) (I
believe) were also present in the list.

I've tried on Arch with both the current 2.6.30 kernel and the 2.6.31
kernel in [testing], and neither has worked.  The version of
iwlwifi-4965-ucode I have installed is 228.61.2.24-1.

Anyone have any idea what might be wrong and how to fix it?  I'll
happily provide any further information that might be relevant.
