<P>解释:这道题是有关WLAN(无线)的知识,题目中说无线网络效率低,但是还是可以用,所以可以采用排除法来</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 做这道题,A答案,加密不对,无线网络不能通,所以肯定不是网络效率低的问题,B答案,没有SSID也不能</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 使用无线网络,SSID是无线网络的一个标识符,必须要有,D答案,SSID不一样同样不能使用无线网络,</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 所以,这题ABD都是错的,他们会导致整个网络不通,肯定不是效率低的问题,所以选CEF</P>
