RE: Promiscuous mode doesn't work on Intel 3945 wireless


I also have the Intel 3945abg on my Asus A6JC. The card does not support
promiscious mode. I went and bought a dlink wireless pcmcia just so I could
play with the airwaves

Subject: Promiscuous mode doesn't work on Intel 3945 wireless

I am having trouble getting my laptop to go into promiscuous mode on its
wireless connection.

It's a Dell Inspiron 640m with an Intel 3945abg wireless card.

Promiscuous mode doesn't work in either Windows XP or in Ubuntu linux (it's
configured for dual booting). Using wireshark, if you try to use promiscuous
mode to capture packets, it won't capture anything at all. It only captures
packets if promiscuous mode is turned off.

Is this a known limitation with this wireless card? Or is there a
configuration trick I'm missing?

Paul
