A question about my firewall another network is asking permssion to be added to trusted zone?

I am using zone alarm, I was printing something on my wireless printer, anyway my zone alarm came up saying it had detected a new wireless netowrk with the ip address 192.168.1.0/255.255.255.0, to share files assign it to the trusted zone, I thought it may be soemthing to do with my printer so I checked it ip address and it is different. I don't know what to do, can anyone advise as I have just ignored it for now.
