I might has suggested that this might have to do with the fact that some people try to access the SmartTV apps immediately after turning on the television. Usually giving the set a minute or so to connect to the router and authenticate solves this issue. Since you've already tried that, you've exhausted my most suggested recommendation.
If you'd like to try reset the television to see if maybe that might help, turn the television on and then press and hold the EXIT button until you're prompted to, "RESET?" Click YES and [Enter]. This would bring it back to out-of-the-box conditions if you like to try and start from scratch, settings-wise with the television, that is.
While I offer that, I don't think it's a setting or the situation with the television, but rather a setting on router that might timeout or a validation that expires. Unfortunately, I don't have the ability to diagnose network settings so you might want to contact your router manufacturer for further troubleshooting options with them.
I recently bought a D6530 SMART LED TV and I often have
difficulties gaining access to the Samsung Apps to download new Apps or use
already downloaded and installed ones.
I click a Samsung Apps button, I often receive the message "Network
Interference Occurred. Try Again
Later". The same applies when I
attempt to access other Apps such as BBC iPlayer.
I have been successful on occasions and used google maps, BBC iPlayer and the 3D
video clips but often appear to be locked out.
I have connected both wired and wirelessly but it makes no difference. I have
also re-started my router several times.
I experience the same difficulties if all other devices on the network are switched
I have switched off the TV, switched it back on again and waited a few minutes
before re-attempting access to the Smart Hub to allow connection to complete
but to no avail.
The TV is apparently not always remembering my wireless encryption code and I
have to re-enter it sometimes to access the Internet. However, sometimes I am
asked to enter the code, decide not to do so, watch TV for a while, attempt to
go back onto the Hub and am successful without entering the code suggesting
that the TV had stored the code after all.

Could anyone please advise of a solution to my problem or Samsung please let me know when you expect to be able to release a fix for my

being overwhelmed with access attempts resulting in the unavailability of the
