I have an application with downloads video from my server.  How can I check to see if the user is connected to the internet so I can gracefully display a message that lets them know they need to connect via wifi/3G/4G to view the video?

I was thinking since I am using jQuery to do a POST to my server and if I get a response back then I can assume that user is connected to the internet.  Is this good practice or is there a better way of doing this?

I've been looking for something similar but not luck, I wonder if there is an API to check if the wifi is enabled, hope someone can help us out here.

You can use the hasDataCoverage() function on the System object

you can also use the blackberry.network property to see what type of network you are on.

Can you determine if the device is being teathered through BB or is on WiFi?

[tneil]

The network property will give you a comma delimited list of all its connection points.. if it is on WiFi it will be in that list

Thank you, I missed that one

@Tim

does the Playbook WebWorks has access to those api call as well?

[tneil]

It has the hasCoverage() function.. not the network one.. the first PlayBook will be wifi only
