Overview

OEM Gemtek WRTR-234GN (WRTR-234GN_V03)

Belkin released two v2 models..

• v20xx, with RTL8366RB switch, working with above mentioned firmware on pg4 of the DD-WRT forum post
• v21xx, with RTL8366SR switch, not currently working with DD-WRT (assigned on DD-WRT bug-tracker)

The default SSID is Belkin_N+_XXXXXX where XXXXXX is the last three octets of the WLAN MAC address (upper case letters).

The device assumes the SSID of Belkin_N+_Wireless_180170 for a brief moment when resetting to factory defaults.

Belkin_N+_Guest is the default SSID for the guest network, but this is not enabled by default.

The power adapter included with the device (v2110) is a

DVE DSA-20P-10 US 120180 (12V, 1.5A).

ID/OD/Len measurements are approximate.
