@Binil yes its solved with firmware update. Send version screenshot I will tell whether it works or not. 

@Sandeep81 

I had the same issue and I found the solution.
In Network->internet it shows all the connections.

in my case one for voip and one for fibre internet . Edit the internet connection, in this there is an option called interface binding. Select all the 4 Lans Lan1 lan2 etc and then select wifi 2.4g and wifi 5g.

Enjoy and thank me later both you boys.
