Solution of the matter: If these from 40MHz to 20MHz down, everything went fine.
Of course, the bandwidth but the bandwidth actually delivered at 144MBit gross synchronization speed on wireless terminal still 8,1MB / s so 64,8MBit is net reduced in this process in view of the fact, I am completely satisfied.
However, the delicacy of this access point is the range!
As this AP with the Typensuffix "LR" more transmit power than most of the APs in the price segment provides, I need now no 2 access points for a decent cover of my object, but it takes is a device completely.
Is special about this UAP series of APs that it can be managed. It installed without further ado a small application on the PC and set up a Network Config. Then you stuck to the access point, makes him find the software, "adopted" him and Zack the Config has been completed! A manageable and scalable solution for this money is completely new to me and therefore I will probably continue to expand future projects with this hardware.
