Hi Alex No, the pool is there for it. The reason it's being disallowed is because I do not have that MAC address in the list of allowed/authorized users. In other words, someone with that MAC is either unaware they are trying to get onto my network, or they are trying to steal service. (I would assume they are unaware since they've been trying now for six days. :)
