Legend of computers = 1 upstairs 2 = downstairs We have 2 computers 1 upstairs and 1 downstairs. I have a d-link wireless router pci card installed on 1 and a regular cable modem in 2. The problem is it says local area network unplugged but its plugged in to the router. # 2 is disconnecting every 5 min and it stays offline for 1 minute and then back up again goes off comes back on. Before we got router it had a direct connection from the cable modem to cpu (2) and it never went offline. how do we get the connection to stay on permantly.
