Can't find the network security key on Xperia T.

I can't find the network security key on my phone which means that I can't tether the phone to the laptop. Does anyone know how to locate the network security key on Sony Xperia T?

Thanks. Have already tried that and cannot find the network key still. Here is a link to a tutorial I found:

http://deviceguides.vodafone.ie/web/sony-xperia-t/customise/wi-fi/use-your-phone-as-wi-fi-hotspot/

I have followed this tutorial but on my phone, it doesn't have "configure wifi hotspot" so I cannot go any further than that.

You can not access to 

settings > more > tethering & portable hotspot >  portable wifi hotspot > portable wifi hotspot settings > Discoverable, power save never, > configure wifi hotspot? 

also since your phone is network branded, there are some carriers/networks that don't allow this unless you pay extra

if that's the case you have 3 options

1) pay extra

2) flash your phone with another firmnware 

3) use another tethering app (check the play store)
