Have you tried the three things I recommend to all users?

1) Windows Firewall - Go to Control Panel->Windows Firewall->Allow App through Windows Firewall, search for MobileSheetsPro and check both boxes.

2) Disable anti-virus software

3) Reboot your router

If that doesn't work, please try the manual wifi connection option in the companion. Go to the Connection menu, then click on "Manual Wifi Connect" and enter the IP address shown on the tablet screen. Let me know if none of this helps.

I have checked the firewall and all seems OK. Updated the PC software and then it worked - once! Now won't connect again. I am very reluctant to disable the anti-virus software. It is there for a very good reason and no program should require it being disabled. I will try with the MobileSheets exe file excluded from the virus protection, but it still does not explain why the connection would work once then cease working.
