I sent my device in for repair and samsung said that they could not find any faults with it and when I contacted live chat because I was still having the issues I was told all they could do is send it back in for repair. I am tempted to get in contact with either trading standards or the BBC's Watchdog Program.
For me can happen after length of time: sometimes every 20 minutes or so, other times once or twice a day. Hasn't happened for 2 days now. It's very unpredictable really
I've been using the tablet non-stop up until today since Saturday afternoon, and it hasn't dropped out yet. I have set it up with WiFi as "Unmetered" connection when first configuring the tablet instead of default "Automatic".
I have the 256GB WiFi version ASH4 firmware installed.
I live in a 2 storey house, router is downstairs in networking closet and I'm on the 2nd floor. WiFi signal is 80% and I'm getting the full 14ms ping, 76/18 mbps speeds. The router is an Asus RT-AC5300.
If its drops out after posting this i'm going to cry :face-with-tears-of-joy:
Still going strong - no issues with WiFi whatsoever.
I read up XDA that its possible its something to do with specific features enabled on a WiFi network that cause this as for some people it works fine at work but drops out at home.
Also - T860XXU1ASJ1 is rolling out, possibly with a fix. So far its out in Germany, Canada and Korea.
