Now i understand why security is changed because im using Fast Roaming and Fast Roaming is not applicable on Satellite Deco Units that's why security protocols are different on Main Deco Unit. Here...

Hey TP-LINK My Samsung tablet detected different Wi-Fi security protocols are compared to my brother tplink router. My Deco mesh system wifi name is AR-TP and my brother wifi name is A9-TP

I'm curious about WPS because WPS is not safe and easily hackable for hackers and i want to turn it OFF but there is no option to turn it OFF even WPS option is useless after 120 seconds WPS still ON.

@SayeemAhmed Yeah you are right and they did'nt provide us all features which has in 10 years old routers.

@SayeemAhmed Yeah exactly even low end routers has this feature like TL-WR840N which is 9-10 years old model but Deco does'nt have this feature even Decos are much better than TL-WR840N as compared...

@ryg Yeah.....Good Luck hope u will get 1.7.0 firmware.
