Hi,
we are implementing a wireless solution at a school. It turns out that response time for whatsapp-users is pretty high when on wifi, changing to the 4G -network delivers almost immediately. (Takes about a minute to receive/send a message). 

Any idea?

Tnx,

Paul

    Hi,

    Done some more testing and is seems that it has something to do with the categories for content filtering on the NSG-200. 
    I tested and checked the categories for WhatsApp and they were not blocked, so I turned off all of the contentcategories...Result: all of a sudden everything worked perfect!
    I have a feeling that there's something going wrong with the filtering...

    Hello @paulb
    May I know which CF categories have you enabled before?

    Hi Chris,

    I made a screenshot of the CF-categories we are currently using (these are the ones causing the delay somewhere)
