Improve WiFi Examples

[hasenradball]

Why to improve

• after connecting to WiFi the return of status takes 10 s due to setup the connecting section code. It is a worse feeling if wifi connecting takes so long.
• remove variable status where it is not used.

Changes

• rework of WiFi-connect section of Wifi Examples
• slightly optimize comments
• slightly optimize Serial output

It would be great if we can bring this to master :-)
