That subject could mean many things?

 

How about explaining what you are doing and where it goes wrong?

 

It also helps if we know which Netgear devices you are playing with.

Visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware.

That page will also have any software, firmware and drivers for your device, if they exist.

Look for the model number on the label on the device.
