Default KitKat Issues

Is it just me or KitKat 4.4 , 4.4.1 and 4.4.2 have more glitches and problems than previous versions?

First: my x1032 just can't connect to WPA/WPA2 secured wifi it always shows this authentication problem, tried re-entering passwords and tried every ROM from the development section and they all has the same problem.

Second: same, tried different music apps and ROMs and no changes, when music is playing and the screen is off sometimes it stops or it stutters other times it glitches and have to restart the phone to be able to play or change the songs. Also, changing songs in lockscreen is weird because sometimes the song name doesn't change but the song itself does it.

If anyone knows what to do, please help
