I surely know that difference and that caused my

question. Read my original post word by word, from the title I used a questioning sense and a question mark.

The PCs don't connect to the Internet, which is not so supprising to me, but the phone works. It is not just you who can think of "當ip電話插上的時候可以用，因為它先獲得了地址，但當電腦再接上去的時候，就無法得到地址了". Nope, I have tried the other order as well. So maybe you should do something before post anything.

"誰都是從不會到會的。"
Apparently you need to learn more.

"但問題是，你應該先自己找一下答案。也許我的這個結論過於武斷，在你上麵的帖子中，我看不出你有努力過的跡象。"
Don't judge others so easily and don't tell others what they "應該". 你看不出我有努力過的跡象 is your problem. Still, if you know 你的結論過於武斷, why not say sorry?

And you have read 充數's post, good -- that is why I say there are lots of smart people but no one likes an aXX.
