Did you finally hire your SSID ? Not broadcast it that is ? If not, do that and write down the name you assign. That keeps all the devices in the house from banging of your network. For me, 2.4 and 5g on an Airport Express have been rock solid. I use the Apple utility to find the least cluttered channel and have my SSID hidden. I also do not use 192.168.nnn.nnn. Based addresses as every consumer device seems to want to default there.
I bowed out of reading about page 9...
Thanks Mal....
I had a lot of advice and help on here when I was going through this and we tried everything there was to try....some things WAY above me.
In the end there was nothing left to do but abandon the idea of using the Samsung. I was getting disconnects with the tablet and router literally next to each other with all other devices off and I live in a rural area with very little wi fi traffic to influence anything so it was a problem from the start.
The developer made the change and now it is rock solid.
He was able to implement features from the iPad app and supposedly change the communication protocol to the one in use on the iPad app too.
