Hi mp,
Thank you for using the Xerox forum.
The solutions available will differ depending on model. If you know your model try entering that here, then select support.
On each support site there is a place to enter text for a search. You may try "wireless settings" or similar. I found many setup articles.
If this does not help please consider contacting your support centre for further assistance.
Please add bluetooth or wireless(direct to phone) for setup of wireless on a desktop device.
Either web-site or App would be very helpful and allow us to get them up and running on the network without a computer, or cable.
