This problem has been happening to me for over the past few months. Whenever my computer goes to sleep after I don't use it for 5 minutes or so my wireless ip changes to 169. It is not the problem of the router as it does not happen to anyone in my family that uses the router. This problem only happens to me. This problem also happens at other places not just my house. For example it happens at school and at my friend's house. I have tried giving myself a static ip but it does not work. I have Windows 8 x64 and my computer is a HP Envy TS 15 Notebook PC.
