Hi Lebret, thank you for all the valuable information from your post below. Are you using it with no issues?

As a new user of the YS-X6, I messed up the settings of the wifi modem and was no more able to access it. Unfortunately ZeroUAV was of no help with that issue.

Digging the net I found the web site of the Wifi module maker and some valuable documentation.

There is a reset procedure involving the opening of the case and shorting LED_NET pin to Ground for 3 sec during startup. When done you have to redo the settings according to YS-X6 documentation and save them, from the USR-WIFIMOD factory state.

In factory state(initial configuration), USR-WIFIMOD-II behaves as below:
􀂄 It’s NET&SERIAL LED Blink in every 2seconds.
􀂄 It will work in adhoc mode,whose ssid is “wifimodII@”
􀂄 It holds a staticIP address “”
􀂄 It works in Udp2Serial mode, and serial access port is 55555.

You have to set your PC TCP/IP properties with
IP static address: (Exemple)
Subnet Mask
Default gateway:

No Wifi protection,

then access the Setup Web page ( admin/admin as UserName/Password)

It may help.

I had issue with serial part of the modem (maybe bad wire between ZeroUAV unit and modem), so I ordered a new one (new generation) from ZeroUAV 2 years ago (oct 2012).

I still have the old unit in my box, but I have to verify if it is OK. Could be useful.
