wgd1206, which/how many devices aren't showing? Can you send me your account address and your full name via private message? I'd like to check things out on the back end.
If you have a wireless extender, your devices, laptop etc will not be picked up. However, if you have a dual band device, it will not see the 2.4 ghz but will see the 5 ghz. I have devices show up on 2.4 ghz between the 2.4 ghz and gateway, but not between the 2.4 ghz extender and wifi laptop. When switched to the 5 ghz the Gateway picks it up. Many people need to use a wifi exterder as it is not possible to place the Gateway in the middle of your house. Hope this helps!
