[SOLVED] WPA-EAP connection fails

ferda · 2010-11-16 14:06:41

At university I use WPA-EAP for connecting to the wireless network.

At boot time, the wifi card can't associate with the router, but when I reload the iwlagn module, it works.
there are no problems at home with WPA-PSK.

can you help me with that?

try this works for me flawless
ssid="eduroam"
scan_ssid=1
key_mgmt=WPA-EAP
eap=PEAP
identity="me@my_university.com"
password="yourpassword"
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"

thanks for your suggestion, i changed the file according to your post.
Now it looks like that:

network={
    ssid="eduroam"
    scan_ssid=1
    key_mgmt=WPA-EAP
    eap=PEAP
    identity="me@my-university.com"
    password="password"
    ca_cert="/etc/cert/eduroam.pem"
    phase1="peaplabel=0"
    phase2="auth=MSCHAPV2"
}

I even specified the bssid of the access point, but it was no use. I think this problem is not related to a mistake in the configuration file as it works after reloading the module and had worked before.
Anyway thanks for your suggestion.

i solved the problem by removing iwlagn from the modules array in mkinitcpio.conf
