As Internet sharing capability is supported via Microsoft ICS (Internet
Connection Sharing), the WiFi-AP Solo will only function as a standard
access point without Internet sharing capability, once its default network
configuration has been altered under the software access mode.
This includes changing the range of private IP addresses that are handed
out (DHCP allocator), enabling or disabling DNS, and configuring a range
of public IP addresses.
