Problem:
Since Android 4.3 update, on Version Samsung Note 2 I continued to get WiFi connection error "Unstable WiFi connection". Also, WiFi internet speed was noticebly low.

I cleared dilvik cache, rebooted, disconnected and reconfigured WiFi - none of which helped. In fact, the problem is not with the phone or operating system. The problem was in my the WiFi network channel. My Motorola router had automatically used channel 1 which was also used by another 4 networks in the the neighborhood.

Solution:
Install WiFi Analyzer on your phone. Find out a channel with the least interference.
Reconfigure your WiFi network to use that channel. I have had no WiFi errors since then.

Good luck.

Thanks!! Worked great. I'm out of the "crowd" now. I think everyone in my neighborhood was on the same channel...lol. Changed mine and now...
Looks like just me and one other in the area on "my" channel now....:D. VERY noticible improvement !!

Use your router settings. Some are Web bases depending on your provider. My unit is a "2wire". I did a Google search on how to change "2wire router settings"......how to and link popped right up. I then changed the channel with my computer....it was pretty easy.

not solved, already install various WiFi Analyzer

======
Did you do the second part ...... installing the WiFi analyzer just tells you if your router signal is in a "crowd"....after that you adjust your home router to a clearer band..."out of the crowd". Your WiFi reception will be better. If it happens on "public wifi" their signal strength being broadcast could be at fault.
