Recently, the company's Windows 10 Notebooks have been having quite a few Wi-Fi issues，One of them would disconnect halfway through use，and afterwards could no longer obtain an IP address。Upon inspection，it was found that the wireless MAC address of this notebook actually changes，The next time it disconnected，inspection revealed the MAC address had changed again。
在檢測的過程，發現原來Windows 10新增了一個「隨機硬體位址」的功能，啟用後即會照成MAC位址變動的情形，設定的地方有兩處：
1.「設定」-「網路和網際網路」-「Wi-Fi」
2.「設定」-「網路和網際網路」-「Wi-Fi」-「特定的AP名稱」
若有遇到自動更改的情形，將此功能關閉即可。
