I have a WHR-G125. I do not use wireless and it is turned off.
Looking at Win 7 Resource monitor there is a continuous network activity involved with the router itself. The addresses shown are buffalo.setup. There are two instances shown. One marked system and one svchost(netsvcs). While writing this message a third started for (network services) and then went away. There is also intermitant traffic to 198.168.11.255. I don't know of anything asigned to 255.
Can anyone explain what all this is please?
