Netgear Routers - Hidden Pages

Here is a list of Hidden Pages in Netgear Routers, some of which I gathered from scouring the filesystem through telnet, note that some maybe be Broadcom/Qualcomm specific so not all pages will show up for everyone:

usage example 192.168.1.1(or just use routerlogin.net)/hidden_info.htm

hidden_POT.htm
hidden_channel_wifi_coexist.htm
hidden_channel_wifi_test.htm
debug.htm (Practically all models)
hidden_info.htm (QUALCOMM chipset based routers/modems only?: ie RAX120 / R7800 / D7800 etc & earlier models?)
hidden_manual_set_ant.html
WiFi_HiddenPage.htm (BROADCOM chipset based routers/modems only: ie RAX200 / RAX80 / R8500 / R8000 / R7000 / D8500 / D7000 etc & earlier models?)
hidden_11ad_setting.htm (R9000)
hidden_cpu.htm
Thermal_FAN.htm
QOS_prru_main.htm

SuperWiFi? Not sure what it is, maybe just increased TX power?... image below, requires use of "inspect" in Chrome to unhide and show in transmit power options.

If anyone finds anymore please mention them. I'll add images/descriptions when I get time.

Since this is a general wireless thread if other brands hidden/secret pages are found please post them and we can change the title.
