1.台式電腦不用安裝ROUTER.用網線連接上ROUTER和台式電腦 (不是CABLE到台式電腦)就可以用了.如果要用無線,要安裝一個台式機的WIRELESS ADOPTER
2.不行.一定範為內都可以上網
3.要設置WEP(192.168.0.1-->Wireless -->WEP Encryption -->128b -->Key Type -->HEX-->輸入一個26位密碼-->Apply)手提電腦無線上網的時候需要設置一個密碼,輸入這個26位密碼,確認就可以了
另外你還可以MAC FILETER通過設置MAC地址防止沒有確認的MAC 地址訪問。192.168.0.1-->Advanced -->Filter-->MAC Filter-->CLONE the MAC address of your laptop and desktop--> select Only allow computers with MAC address listed below to access the network-->apply
you can find more info in Help when you log in to 192.168.0.1
good luck
