Regarding third party firmware support, Realtek SoC support in OpenWrt
+ (success) RTL8196C port status. on the OpenWrt Forum
and the Realtek thread on the DD-WRT Forum may be of interest.

AC1200 Wireless Concurrent Dual-Band Gigabit Router

 • Product page  • Datasheet

The FCC test report indicates that the Edimax GR-478AC
and the ZyXEL X650 are also covered by the same FCC ID.

  • "1244-010000842-50Z" is silkscreened on the main board of the FCC EUT.
"1244-00000861-50Z_ES" is silkscreened on the wireless module of the same device.
  • "1244-010000892-50Z" is silkscreened on the main board of a production model.
"1244-00000861-50Z" is silkscreened on the wireless module of the same device.

This device is likely using RTL8367R as the Switch IC.

By default, the device broadcasts the SSID of edimax.setup on both bands.

  • The power adapter included with the device is likely a DVE
DSA-12PFA-05 FUS 050200 (100-240V 50/60Hz, 0.5A -> 5VDC 2A).

Flash Information[edit]

There's a datasheet for the flash used: MX25L3206E

Can confirm that the flash chip on here works when connected to
a raspberry pi and spi modules are loaded with flashrom 0.9.8. [1]
This system shares the same bootloader as the RTL8651c. In fact, in
Edimax's GPL release, their embedded instructions are for said system.
