I have a telephone which has an ethernet jack in the back (it uses VOIP). It will sit on the 2nd story of my house. My wireless router is on the first floor of my house.
What wireless adapters/hardware do I need (if such hardware exists), so that I can connect my phone to my network wirelessly as opposed to physically running an ethernet cable? For example, would either of the following devices do what I am looking for?
Please include link to a device(s) so I have an example of what kind of hardware I need.
