sairfan1, I already told you one way (probably the easiest) to set this up, so you can remotely run the CNC.
As a normal setup would be...
USB host (PC) - USB cable ------------ USB peripheral (CNC)
and given you are trying to do the following instead....
USB host (PC) - USB port - USB (Type A) to wireless --^^^^^^^^^-- wireless to USB (USB Type B) - USB peripheral (CNC)
Basically you want to replace a cable with a wireless connection but make it behave like the original Type A (PC side) to Type B (CNC side) cable. Perhaps there is something that exists to do that, but I've never seen such a thing. The closest approximation are the old wireless print servers that would allow a printer, with no wireless support, to be connected to a WiFi network. Some of them could be connected via the USB Type B connector, but something like that won't suffice to replace a USB cable (the really old ones were parallel port with Ethernet RJ45 jacks).
The problem with such a beast is that there probably isn't much of a market for such a thing. If a peripheral has a wireless connection it typically has WiFi built in, e.g. like a network printer (my home network printer has a USB-Type B port but it also has a WiFi connection, so I use WiFi to send print jobs and scan documents).
