As you probably know V9s firmware is still not stable , having been using for last 3 weeks so many issues
Lately today once i started the openbox V9s the screen on the TV was just openbox and nothing worked
a. pulled the power wait for 2 minutes plugged in and then only the radio channels worked
b. Tried to pull the software update gets no network interface then connected to wire network did the full reset , full software etc all working fine.
c. connect back to Wifi connected to my SSID network connection successfull , later after few minutes scramble channel again, powered off and power on but still then go to network setting and connect again works for few minutes

In short the wifi on the V9s is broken have seen in other forums to have similar issue.. So please take the back up file which will be very help full to restore

Thanks
