I was having the same kind of issues earlier, the wifi connectivity was dropping all the time on my Note 3.
to turn power saving mode off,
dial *#0011#
go to wifi
and then turn it off
I just tried this and my device is now well faster on Wifi. I though I had done this before but looks like I haven't.
Thanks for the advice. Worked a treat

I was having the same kind of issues earlier, the wifi connectivity was dropping all the time on my Note 3.
I downloaded a wifi analyzer and it clearly showed that my internet had the best connection and least traffic.
I solved this issue by downloading the latest update and turning wifi power saving mode off.

Yes I have experienced it a lot but I guess I don't pay much attention but I will now.I just ran a speed test and got 3.9MBPS on a wifi desktop yet the wifi on Note 3 says it Can't load search results when trying google search. It will load other things like face book comments and even photos.
