Exclamation REALLY strange problem with TL-WN422G (atheros)

Hello everyone!
I've recently bought TP-Link WN422G wireless adapter with atheros chipset.
I've followed this guide successfuly and now I can see the adaptor with iw/ifconfig.

However, when i try connecting to ANY wireless network (no encryption and pretty good signal) I get error "unable to get IP".

I've ran wireshark to see what is happening when I try to connect and - voila! It immediatally got connected!

I've tested at least 30 times connecting to the AP with and without wireshark running, and I can connect with no problems while it is running and not at all while it isn't.

So, I'm just asking what does wireshark have to do with connecting to router at all?

Maybe something in the syslog or kernel ring buffer can shed some light on what's going on...

Problem solved.
I spoofed the MAC of the card and Wireshark put the card into the promiscuous mode so that was the cause.
But that's still strange because all other cards I've tried work fine when I spoof their MAC without being in promisc. mode...
