BUT: a connector for a wired connection is available in the room! RJ45 cable to RAVPower and already has a secure connection with simultaneous login of 5 devices possible. Data Transfer with 7 Mbit / sec. for jd. Device as fast as it would be directly connected to the (unprotected) cable.
Advice: Always take a cable (in my case, 10m) and room search for a cable connection -> best performance and high security!
