Can you clarify what you are wishing to do?
Are you trying to get online through your home wifi connection or something else?
If you are trying to get online at home can you tell us the make and model of your wireless router or modem?
Can you flip the Dell router over and give me the model number so that I can give you the correct steps.
In that case I am going to have to opt out and see if another expert can help as I have no experience with your router.
