Thanks Mark,
I tried to go into Windows Firewall and by some clicking got an error message:
The Windows Defender Firewall with Advance Security snap-in failed to load. Restart the Windows Defender Firewall service on the computer that you are managing.
Error code 0x6D9
I found the Services and Windows Defender Firewall and select [Start] the service, and with a [Start] that got a warning:
Windows could not start the Windows Defender Firewall service on Local Computer.
Error 1062 The dependency service or group failed to start.
Windows Defender Firewall shows Startup Type: Automatic, and Log On As: Local Service
I've called the repair shop but they can't help me over the phone until Monday. In the meantime I've gone into Windows Security and Maintenance and have added CumulusMX.exe in the Exploit protection and can't see how I can add WLL there. I really don't know what I am doing but giving it a try anyway. Is the no broadcast error I am getting about CumulusMX not being able to access or a WLL transmitting issue? and where would I find the port listing?
Enjoy,
Paul
