Add new device to network from list of allowed devices not currently connected to the network

[ChrisC_2010]

How do I move a device from "list of allowed devices not currently connected to the network " to allowed and connected?

If the device is connected it should move there automatically.

Is it connected and not showing as connected?

It is connected but not showing it is connected.

If it IS connected then it is possible it is showing as something different. If this is a WINDOWS PC/Laptop run in a command prompt IPCONFIG /ALL and see what it shows for the gateway. It could be possible your modem is putting out a Wireless signal and the device is connecting to that? IPCONFIG's GATEWAY would show that if it doesn't match the Router's IP Address for instance.

Also you could have in the list and old DHCP IP Address handed out and the device is using a new one.

More info and a screen capture of the attached and not attached devices would help.
