N+ Wireless Router

 • Support page

Manuf. (and perhaps designed) by Gemtek, WRTR-235GN (WRTR-235GN_V01).

There is a NEC USB controller on-board.

The default SSID appears to be Belkin_N+_XXXXXX (where XXXXXX is replaced by the last three octets of the wireless interface MAC address [capital letters]).

When resetting to factory defaults, it seems the device temporarily assumes the SSID of Belkin_N+_Wireless_180170.
Belkin_N+_Guest is the default SSID for the guest network, but this is not enabled by default.
