Re: Samsung Note 3 disconnecting WIFI constantly (fix)
it did not work for me. I still got disconnected from a strong WiFi. On one occasion, I watched as the device immediately reconnected, and it took some time to get an IP address. So, the suggestion of using a static IP address makes sense. Perhaps the device will disconnect just as often with a static address, but may recover immediately, so it may pass unnoticed.

While this was enabled (as default). the device was hesitating between WiFi and 4G, not getting any single one right. After turning it off, even if a disconnection happens, I hardly notice it, unless I'm loading a page from the Internet at that very moment.
There is also another WiFi switch which I turned off: Scanning always available. This allows the Location Service to "scan for networks even when WiFi is off". I'm not sure how WiFi helps with location, for example, how would my home WiFi know where I live ? Turning it off seems to have helped, but I'm not yet sure it made much difference. The only side effect is that when I'm in a car and looking at Google Maps, I need to turn this flag back On again, otherwise there is no location informatioin. Again, I don't understand how WiFi gets involved when the device asks nearby Telco towers about the location.
A third switch I turned off relates to the Power Saving mode. I turned off the "CPU power saving" flag. I just speculated that the device might have a lot of things to do at the same time, so it may lose track of WiFi. I'm not using any CPU-intensive apps. So far, this flag made no discernable different, so I might turn in on again.
The only thing I haven't tried yet is deleting the partition. I might do that, if it gets worse. For the moment, it is only annoying, to know I have a powerhouse of electroinics, but is less stable on the WiFi than half dozen older devices I got at home. It behaves similarly at my work WiFi. The peculiar thing is that the disconnection is not due to radio reception being out of tune. I had some older phones which could hardly get any WiFi signal at a certain spot at the workplace. I only pass there for short periods of time, and Note 3 stays connected and gets data from the WiFi.
