Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
The short answer is that no, you cannot.
Faxing requires a telephone line.
While it is possible to fax through the internet, it would require a VOIP device and a subscription service (such as through vonage, ooma, etc).
You cannot fax directly through wifi, some type of phone line would still be required.
There are some "efax" options available as well (also require a monthly fee), where you scan an item and upload to a site then enter the number to fax it to. Received faxes (they provide a dedicated number to you) are emailed to you.
do remember to rate my service prior to logging off, hopefully I have earned an “excellent”. I also invite you to contact me directly with any future support needs at http://bit.ly/1Md4aNC
Thank you, ***** ***** a good day,
