Powerline Wireless Network Extender
"GPN2.8P61A-C_WIFI_PCB-ACTION", "REV: 1.0", "TB49193B0 B7", a lead-free logo, and a date code of 1328 appears to be silkscreened on the main (Wi-Fi / Ethernet - non-Power/PLC) board in the FCC photos.
Per the FCC photos, this device is using the following...
- Atheros AR7420-AL3C (PLC SoC)
- Atheros AR9341-AL1A (WiSoC)
- at least one Airgain N2420S antenna
Default settings are from the FCC manual. They may be inaccurate.
The sample SSID shown in the manual is Actiontec. The sample label indicates the format is Actiontec-XXXX.. but that could certianly be inaccurate too..
