Static Ip or Virtual Ip

Question 1

I have a dynamic ip... how do I set a static ip?? I saw tut for windows for setting static ip by changing the setting of ipv4... but how do I do that on kali??

Question 2

I saw about virtual ip in kali... so I set wlan0 as dynamic and set a wlan0:1 as a static ip.. then I tried meterpreter but cudnt get a session on wan...

So how can I do that??
