Wifi on acer liquid E2

[jalbersen]

hello,

so i just have my acer liquid E2 and i have a strange problem.
i get the app facebook with it i dont mind about that i use it but sometimes it doesnt want to refresh the page this is the same for the playstore sometimes it just doesnt want to load.
now i saw on a other forum that there are problems with android 4.2.2 and wifi. the strange thing for me is everything else is working fine.
what's app working, facebook messenger working, hangouts working i get a messege if i refresh the page.
error refresh the page check your connection. the problem is my connection is working how can i what's app if my connection is down (and yes im using wifi for it not my credit).

EDIT: most of the time its happening when i didnt use the app for a time or when my mobile is getting out of stand by

some one a idea why it isnt working?

thanks a lot.
