Hi Yemi,
It all depends on what it is you want to do and how much experience you have.
Although there are some minor correlations, Security+ and CEH are different.
The Security+ is a highly regarded "entry level qualification" that provides a basic, more holistic overview of IT/Information Security, covering numerous security domains inc. Authentication, Security Threats, Network Security Concepts, Business Continuity, Operational Security etc.
CEH (Certified Ethical Hacker) is an excellent qualification, however it is pretty specific to the world of Network Security and Penetration Testing. So from your point of view, as a CWNA, it would definitly compliment and enhance your current experience.
Depending on your background, the SSCP by (ISC)2 may be worth investigating.
The CISSP is obviously, "The Holy Grail" of IT/Information Security qualifications. Internationally recognised and a badge that all security professionals aspire to achieve.
If the CISSP is the direction you are looking at, I would suggest looking at the CISSP CBK (Common Body of Knowledge). It breaks down the domains and criteria for getting the qualification.
Cross-reference that material with your experience and then look at what you have to do to get there. That will give you a "step-by-step" breakdown of what you have to do to achieve your goal!
As a summary, if you have the resources available then I would consider doing both the Security+ and CEH. The CEH will enhance your current skill sets and enable you to provide technical expertise on Wireless Security (through effective penetration testing etc), and the Security+ will give you an insight into the other domains.
I hope this helps!
