Linux無線ESSID:off/any的錯誤

Linux無線ESSID:off/any的錯誤 我用的Distribution是SUSE，昨天上網發現無線網路突然掃描不了，在命令列下輸入iwconfig wlan0得到的結果為：  www.2cto.com  wlan0     IEEE 802.11bgn  ESSID:off/any            Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm             Retry  long limit:7   RTS thr:off   Fragment thr:off          Encryption key:off          Power Management:off這個資訊說明任何無線都無法被掃描到。 查了很多資料都不知道是什麼原因。輸入命令/etc/init.d/network restart得到的結果為：  www.2cto.com  Shutting down network interfaces:    eth0      device: Realtek Semiconductor Co., Ltd.

 發現圖中的“啟用IPv6”選項被勾起來了。把該選項前面的勾去掉，無線網路恢複可以為正常掃描。問題解決！
