On laptop or notebook computers that use Intel PRO Wireless 3945ABG built-in Wi-Fi network adapter in Windows Vista, the WiFi radio signal may just suddenly turns off, shuts off or disable randomly, with the Internet or network cuts off.對筆記型電腦或筆記型電腦使用英特爾PRO無線3945abg內置Wi - Fi網絡適配器在Windows Vista中， WiFi的無線電信號，可能只是突然關閉，切斷或停用，隨機，隨著網際網路或網路切斷。 The wireless network connection may still appear as active and connected with Excellent signal strength in Network Center, but the network status will change to Limited Connectivity.無線網絡連接仍可能出現積極和連接具有優良的信號強度在網絡中心，但網絡的狀態將變更為有限的連線。 If the system has LED indicator for Wi-Fi wireless radio signal status, the LED light also turns off (may also stays on) and Wi-Fi radio power cannot be toggled back on with Function hotkey (such as Dell QuickSet), even though the software detects the toggling or pressing of keys with WiFi and Bluetooth logo pop up.如果系統已導致指標Wi - Fi無線電台信號的地位，發光二極管發出的光也關閉（也可停留在）和Wi - Fi無線電的權力，不能切換回就與功能的熱鍵（如戴爾quickset ） ，即使該軟件偵測切換或迫切的鑰匙，與WiFi和藍牙標識彈出。 It looks like the Wireless adapter card loses its power and are completely shutdown and powered off.它看起來像無線適配卡失去其權力，是完全關機和電源關閉狀態。
Even when the problem happens, the network device appears working properly and normal in Device Manager.甚至當問題發生這種情況，網絡設備出現的正常工作和正常的，在設備管理器。 The IP address auto-discovered by DHCP may be lost or gone.
