My HP laptop will lose communication with Mitsubishi PLC occasionally after removing ethernet cable to download from WiFi.
Our company limits the ability to use the wi-fi when I have an ethernet cord connected to my laptop, it has to do with security.
If I am connected to the Mitsubishi PLC, then want to download another file from our autosave, which we connect through the wifi, I have to remove the ethernet cord from my HP laptop to enable the ability to go wireless, however sometimes when I attempt to go online with the PLC after I re-connect my ethernet cable, GX developer will not allow it. I can ping the plc and even go online with other PLCs on the network, but for some reason, the one I was connected to will not connect. I restart my computer and even re-download the file again from autosave but no joy. Its not until an unknown amount of time that it will allow me to re- connect, its as if I lose the socket connection on the plc and it needs time to reopen. I talked to our IT department and they have no ideas.
Thank you in advance for any help on this matter.

I am not sure about other times but I believe I didn't close out the connection before I removed the ethernet cord last night when this happened. I will make sure I do this from now on as this may be my issue although the timeout function on this PLC (Q series) is longer than 15 seconds, as last night it lasted a half hour at the end of the shift and I was still not able to connect. This seems like a very plausible reason for my issue. Thank you for your response, I will follow up in a week if I do not have any issues with it again.
