✔ 最佳答案
The wireless card on your laptop might only be capable of WEP security (kinda old) while your home network might be set to WPA (not as old) or WPA2 (very current, highest security).
One thing you can do it to download Windows SP3 (run Windows updates and look for Service Pack 3) because it provides for a universal wiress driver that will upgrade your laptop to the WPA2 level and then you should be able to connect.
Good luck.
