Query: Not a complete study guide for the PW0-100 exam

I liked this book but as the CWNA study guide it falls short of expectations. The PoE coverage was almost entirely lacking and there were many other areas that did not fully cover the exam question areas. I wrote CWNP and received a lame excuse as to why it was not complete and to disregard the claim printed on the cover that it provided "Complete coverage of the CWNA exam objectives". They said the exam has gone through considerable changes since the book's publication and thus does not match in many areas anymore. I suggested an on-line suppliment to cover the changes and they said that was not necessary, I should research the changes myself. As the exam study guide it deserves 2 stars, as a general guide to wireless networking it deserves at least 3 or 4 though obviously it is getting dated.
