I’ve recently had an issue with one of my boxes, where the WiFi interface will not let any new connections in unless a connection out is established first. The connection can be established by anything, a ping, a ssh connection or anything.
I can’t track down what’s causing it. It’s using a RTL8187 USB stick with an external antenna with a 2.6.39 custom kernel. The same thing happens on a 3.3 kernel however.

iwconfig is reporting that power management is off, and I have disabled wireless power management in the kernel also.
Is there anything else that anyone can think of ?
Any more information needed to help me troubleshoot this ?
