大家好我想請問用wpa_supplicant建立wifi p2p連線的問題 [問題] 我用筆電雙系統的win7配合intel的wifi p2p軟體，我可以用手機的wifi direct搜尋到NB。但是當我使用Linux時，在wpa_cli中打p2p_find [timeout]，會直接跳出FAIL。我啟動wpa_supplicant的debug mode (wpa_supplicant ... -dt)，在wpa_cli出現FAIL時並沒有跳出錯誤或警告訊息想請教諸位前輩這種狀況我應該朝那邊走？我不清楚問題點到底是在driver不支援還是wpa_supplicant設定有問題，還是在其他地方...Orz [網路資訊] 有人說 $ iw list吐出來的訊息中， supported interface mode沒有P2P_GO & P2P_client就是設備不支援 => 不過win7的環境可以用p2p搜尋 => 另外想請教，iw list是顯示wifi chip的資訊還是driver看到的資訊？ iwlwifi-1000 (intel wireless driver)本身不支援P2P Linux wireless上提到的 => P2P我以為可以靠更上層的軟體解決，還是這driver不支援就沒辦法？ wpa_supplicant的README本身並沒有提到這點，他只有說: Linux drivers that support cfg80211/nl80211. Even though there are number of driver specific interface included in wpa_supplicant, please note that Linux drivers are moving to use generic wireless configuration interface driver_nl80211 (-Dnl80211 on wpa_supplicant command line) should be the default option to start with before falling back to driver specific interface. Linux drivers that support WPA/WPA2 configuration with the generic Linux wireless extensions (WE-18 or newer). Obsoleted by nl80211. In theory, any driver that supports Linux wireless extensions can be used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in configuration file. 我自己是比較偏向wpa_supplicant的設定是不是有問題, 設定檔如下(.config) http://paste.ideaslabs.com/show/3SHxXWBuJK runtime config: http://paste.ideaslabs.com/show/3GzWKUcbWR [環境] 硬體環境為thinkpad T410 (Intel Centrino wireless-N 1000) OS: Debian 7 libnl-3 libnl-3-dev wpa_supplicant v2.4 wpa_cli v2.4 iwlwifi-1000 39.31.5.1 (intel driver) -- $ iw list ...
