android 4.1.1 network connectivity issues device: asus memo pad mev172v

issue: Apps (facebook, play store, ym, skype, etc) cannot access the wifi network. I can browse using Chrome (except for SSL sites) and can use the Youtube app.

tried:


rebooting via safe mode
clear app cache
removing and adding accounts
As the OP didn't add the solution as an answer himself...

OP found the answer to the issue himself, strange as it might sound:


  noticed that the device date and time is not correct. corrected it and it worked.


On a second thought, this is a very plausible reason, considering the questions hint about except for SSL sites: If the local date is too far in the past, SSL certificates are "not yet valid" -- and if it's too far in the future, they are "no longer valid". In both cases, establishing a secured connection must fail.
