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 22.214.171.124-1.
Anyone have any idea what might be wrong and how to fix it? I'll
happily provide any further information that might be relevant.
