WIFI Access Denied!



  • Here's hoping for a simple fix. When I tried to start my Duet WiFi printer today, the computer couldn't find the http I use for my printer. When I plugged my Duet into the computer via USB and started YAT to see if I just needed to turn on WiFi again, I got the following message for the com port on which I have the Duet:

    **Terminal Error

    Unable to start terminal!

    System error message (System.UnauthorizedAccessException):
    Access to the port 'COM6' is denied.

    YAT Hints:
    Make sure the selected serial COM port is available and not already in use. Also, check the communication settings and keep in mind that hardware and driver may limit the allowed settings.**

    I get the same error message regardless of which COM port I use. I'm assuming it's a problem with the WiFi module. Any help would be appreciated!

    Thanks in advance,
    Tony



  • Some additional information:

    I just remembered that for the past few days, my Duet WiFi has been randomly disconnecting several times during various printing sessions. The print continued, but the connection was lost several times and I had to manually reconnect. Bad WiFi module?

    The WiFi module has nothing to do with that message. The problem is on your PC. You may have another application running on it that is connecting to any available serial ports; or you may need to run YAT in administrator mode; or you may just need to reboot Windows.



  • Mystery (Apparently) Solved.

    First a big thank you, as always, to DC42 for such great support!

    I believe the problem was with a Windows 10 update. This morning, I noticed that the machine had recently updated so I uninstalled/reinstalled the update. Everything is now working fine. Just one of those things we (or I) don't normally check. So, lesson learned. 🙂


 

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
