Does ABWIFI Library work under B4A 1.70?

I don't think that it is related to v1.70. Are you getting any errors? Did you check the unfiltered logs?

My mistake it's working

It works - I made a dumb mistake - when you have code thats waiting for a button click before it does anything - it makes sense to actually define a button and a layout

Once I did that and clicked on the button, it worked. Glad that I did this with a 'known' working wifi library as I wrote my own wifistatus library once I saw how the ABWIFI library worked. My library (now) returns the DNS name - although it still needs to be cleaned up (error handling etc) which answers my other question http://www.b4x.com/forum/basic4android-updates-questions/12630-how-can-i-determine-dns-server-s-being-used.html#post71116
