點解上唔到網?(wifi)

我arm arm砌左新機..
裝左window XP SP2.
router係XyZel既.無線卡本身係d-link不過唔得..
所以轉左用level one既USB wireless.

e+如果我用window幫我連既話呢.
佢就連IP address都收唔到.

如果我自己用adapter連..
IP,,DHCP都有.
但係就係冇DNS同WINS.

但係無論我用window幫我又好.
adapter幫我連又好..
當我每次同修復功能之後.
佢都話我接收唔到IP address..

點解既???可唔可以答我..
我好想部機快d有得上.
thzzzzz!

p.s.e+呢部laptop都係透過我屋企部XyZel既router..
但內置adapter..都上到..
但點解我部pc會上唔到><
