Don't forget that you can't have two machines running with the same name on a Samba network. PP defaults to:
Code:
Hostname: tormachpcnc
NetBIOS: TORMACHCNC
Workgroup: WORKGROUP
You need to modify these in order to have both machine running at the same time if you are using Samba - sounds like you are.
Also, ditch the WiFi and run some cat 5e cabling to your router.
In my experience it has not been a problem to run both my PCNC1100 & Slant-Pro on my home network. This network spans the house, barn, & workshop. I have plenty of traffic on this network without any issues. Just make sure your routers firewall is setup and you have changed the default admin login settings.
