The SRR60 default image config looks perfect, but it looks like I will need to self compile the SRS60 image so that it is by default a Wireless Access Point that bridges over the QCA9984 wireless interface.
Would anyone be able to give me pointers regarding the correct configuration for a self compile for a wireless access point with no WAN or Firewall required?
OpenWrt isn't intended to initially boot into a ready to use condition. You will have to log in and configure each unit to meet your needs. Hardware with more than one Ethernet port starts out with a very basic lan-> wan routing setup with one port the wan and the rest LAN. The wifi is always turned off, so you have to connect by Ethernet.
