Tim Moody & I tested maximum WiFi clients on the 5th and 6th generation i3 Intel NUC's, extensively confirming this with CentOS 7.2 in different locations (to be 100% sure radio congestion was not causing this!)
We were very surprised (and a bit shocked!) that even the little RPi3, which tested to serve 32 simultaneous WiFi clients from its own internal WiFi Access Point (AP), far outperformed the pricier/bigger Intel NUC's internal AP's here. Does anyone know if there might be any kind of a soft-limit within CentOS or its included (Intel presumably) WiFi drivers? Ideally expandable to many more simultaneous WiFi client machines? These are the internal 2 WiFi modules in question: http://ark.intel.com/products/83257/Intel-NUC-Kit-NUC5i3RYH contains: IntelĀ® Wireless-AC 7265 + BT 4.2 http://ark.intel.com/products/89189/Intel-NUC-Kit-NUC6i3SYH contains: IntelĀ® Wireless-AC 8260 + BT 4.2 We have many more of this latter 6th generation NUC in circulation (i.e. newer, higher-performance WiFi module 8260). FWIW most of these NUC's had May/June firmware SY0045.bio installed in late spring 2016, but have now been upgraded to the brand new early August firmware SY0051.bio: https://downloadcenter.intel.com/download/26195/BIOS-Update-SYSKLi35-86A- Adam -- Unsung Heroes of OLPC, interviewed live @ http://unleashkids.org !
