Have a network running mix of xp and vista. A power outage crashed a router and access point. Since then we are having problems with internet connection. I run the sniffer program and I can see a reporting of an ip address of 192.168.0.255. This address is there all the time and makes a link to every computer and network printer on the network. This is not the ip address of the router or access point. It is also not the displayed address of either. I cannot ping it nor trace it. But it is hogging my bandwidth.
