I have read about every post in this thread and am even more confused than before.
I'm using a Sierra Wireless Card model 875 with AT&T. The card connects to a different tower every time I connect, and, as far as I can tell, my ip address changes, too.
I can receive DCC usually, but can never send. I am not aware of a firewall with AT&T and I have no firewall options checked in my MIRC.
Like all of the others with the inability to DCC send, this is frustrating. I paid for MIRC and would like to get some help in possibly resolving this.
Can anyone help?
