ud-ultcdl looses network connection after using Belkin USB-C to ethernet adaptor.

I had a network connection fail on UD-ULTCDL after using belkin usb-c to ethernet adaptor, had to re-install the “plugable / display link software to fix”. This is not a long term ideal solution each time I go on the road.

Thanks Josh, running it now and will email it to you.

The belkin adaptor is F2CU040. It worked straight out of the box. no drivers needed manual downloading.

Maybe you could send me your email, I only have a noreply.plugable etc one.

Running the plugdebug seems very slow, stalled at the compressing stage, how long should that stage take. been over 45 mins now!

gave up waiting for the debug program to say it had compressed and emailed the file FAO Joshua Henry. Awaiting a response. Thanks! Leo

Thanks for sending the file. I will take a look and be in touch shortly!
