I have a LINKSYS WAG320N Router. When I look at the DHCP Client Table some "connected" items are listed even though they are not currently switched on whereas others (ie my mobile phone) disappear when I switch them off and then refresh the table. Can someone tell me why? Also, I have an "Android" which the table lists yet I haven't a clue what it is. When I do a search of its MAC address it says "Murata Manufacturing Co., Ltd" which doesn't tell me anything. Any clues please?
