Samsung Galaxy 3 Tab Lite - internet functions locked out & sync error message

[AC Question]

My son has a Samsung Galaxy Tab 3 Lite. Periodically the Internet functions lock down, and when you investigate the various accounts you get the "sync currently experiencing problems. Will be back shortly" message. This has always sorted itself out in time, but sometimes takes several days to do so, the same then re-occurs a few days later

Welcome to Android Central, and sorry for the delay. Does this happen on any wifi network, or only your home network?
