Yes using sdk5 build right now
I uploaded the firmware through administration then I factory reseted using the 192.168.1.1 website.
I'm not sure about the cfg loading thing.
Not apple devices - all devices are disconnecting on WiFi but ethernet is fine
.........
so far in my sdk5 test - my 4 bar went to 5 on my desktop with a pci express card so range / signal strength got better
