I have a certification at the Master Level Wireless from NARTE, but I am looking to get more wallpaper for better job security. Contrary to some IT gurus, I don't think the CCNA fits for further certifications. First, it is proprietary and second it isn't helpful. I took a CCNA boot camp and dropped it after the second day. What else do you suggest?
I have nothing against CCNA, but it is very much an entry-level cert into the Cisco world. It really takes a professional level Cisco cert (CCNP, CCDP are good, but CCSP and CCVP are better) to get noticed, and of course, the CCIE remains something of an evergreen, high-level certification and looks likely to stay that way for the foreseeable future. If you don't want to go proprietary, though, your options are kind of limited: you could dig into the Planet3 Wireless/CNWP cert track (CWNA, CWSP, CWNE) but that may be gilding the lily considering your current Master NARTE status, or perhaps you could branch out into security (the CISSP and concentrations are well-received, and the CISM likewise), which has to be a major concern from the wireless standpoint anyway. Another option would be to consider an advanced degree, MA/MS or better, if you don't already have one of those.
Hope that helps,
