Embarrassing. 小弟好歹也算是IT界, 居然做左免費wifi 一陣子, 可能是片刻到最多兩星期. 打開management page 見到一部 hostname: lyle-PC (MAC address start with: 00-1C-BF, intel chipset) check 過disable broadcast SSID, enable WPA2, MAC address white list, (得iphone會用到wifi) 唔明白如何進入我的network 而Dlink 會assgin IP…. anyway, 改ssid, password, reduce antenna power to 25%, 即刻save & reboot, 然後這個星期每天都check 一次, 不再見到lyle-PC……. 難道一開始set 完security 冇reboot? 唔會掛…. 我都幾肯定我有按…….
