Dell TB16 / XPS 13 9350 / P2715Q - Monitor goes blank when computer lid is closed.

I updated drivers on all devices, including setting the XPS to do nothing when lid is closed. External monitor works fine, until XPS lid is closed, then external screen blanks. However, monitor works fine in airplane mode, which does me no good, as I need an active internet connection for certain software functionality. Also, airplane mode disengages my wireless keyboard and mouse, and I need to turn connection back on and pair devices (wasting more of my time). Is there anyway around this issue, other than returning the TB16 for something that works?

Assuming you have a Dell-branded Broadcom internal Wi-Fi adapter, if you lower the transmit power to 75% as described here -> plugable.com/.../  does that help?

Thanks for the reply, the system does have a Broadcom Wi-Fi adapter, however, system was transmitting at 75%. No change in status. I even PM'd a known Dell "engineer" explaining problem, no reply or response. Calling in for technical support was useless, Phillipine call center provided two experts, guy named Rocko, then woman named Chantelle (ridiculous caller nicknames), who were no help. I could barely understand them with their heavy accents! So much for DELL support......seems like a known issue is just going on deaf ears. At this point, ready to repackage all gear for returns.
