그러나 이것을 어떻게 해석해야 할지 모르겠습니다.
ESSID가 설정되지 않은 이유는 무엇입니까?
iwconfig를 수동으로 실행하면 ESSID를 설정할 수 있습니다.
sudo iwconfig wlan0 essid UNIVERSITY-SECURE
$ iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"UNIVERSITY-SECURE"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=15 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
$
그러나 분명히 연결이 작동하려면 ESSID 이상의 것이 필요합니다.
대학 WPA의 내용:
network={
ssid="UNIVERSITY-SECURE"
scan_ssid=1
key_mgmt=WPA-EAP
pairwise=CCMP TKIP
group=CCMP TKIP
eap=PEAP
identity="my-user"
password="mypass"
ca_cert="university_comodo_cert.pem"
phase1="peapver=0"
phase2="MSCHAPV2"
}
저는 이 설정을 사용하여 아무런 문제 없이 다른 컴퓨터에 연결했습니다. 하지만 저는 항상 -Dnl80211을 사용하지 않고 -Dwext를 사용합니다.

운전사는 입니다 iwlwifi.
이것이 iwlwifi와 -Dnl80211 사이의 문제입니까? 이 문제를 추가로 진단하려면 어떻게 해야 합니까?
답변1
결국 -B를 제거했습니다(백그라운드에서 데몬 실행).
sudo wpa_supplicant -i wlan0 -c wpaconfig -D nl80211,wext
내 스크립트가 연결이 완료되기를 기다리고 있지 않다는 것을 깨달았습니다.
wlan0: CTRL-EVENT-CONNECTED - Connection to 00:11:22:33:44:55 completed [id=0 id_str=]
essid가 보이지 않아서 일찍 중단되었습니다. CTRL-EVENT-CONNECTED에서만 프로그래밍 방식으로 데몬을 요구하는 옵션이 없는 것 같으므로 wpa_supplicant이를 위해 Expect 스크립트를 사용해야 할 수도 있습니다.
