[Solved]Connecting to University Wi-fi

MasterNate · 2012-08-31 22:12:51

Recently installed arch on a laptop I bought for school, can't connect to my schools wifi. Well I can, but I can't get an IP from it. I run wpa_supplicant, it connects and authenticates (WPA2-Enterprise, PEAP, and MSCHAPV2) however I still can't obtain an IP, I run dhpcd and get the waiting for carrier error, but when I tried to

iwconfig wlan0 channel auto

that didn't help anything. After a few googles, I can't find any help on this particular issue, any advice would be appreciated!

I'm marking this as solved, but it isn't really I suppose. My network profile (see post below) works, but not every time. I can't decide if that is a network issue or not though, because the wifi here is notoriously bad. When I run

 netcfg "wireless profile here"

sometimes it works, but most of the time it does not. I either get a WPA AUTHENTICATION / ASSOCIATION error, or a dhcp timeout, even as I was typing this my wifi cut off. I worked around the dhcp timeout by increasing the time in my network profile. "DHCP_TIMEOUT=30" and that helped some. Thanks for listening to my wifi woes and all the help, hope something I found helped any future readers with their problems.

Those commercial cisco routers giving you trouble?
You might need to open up a webbrowser to get some credentials to use the network, but even then, it still gives you an address to do that with.
Without wpa_supplicant, I would try it manually.
iwconfig wlan0 essid <whatever> enc <whatever> (probably not encrypted)
dhcpcd wlan0
You must specify an essid to connect to and there may be several carriers with the same name on the campus network only differentiated by MAC address.
I would also try wicd, to sort out the possible confusion.

I had trouble connecting to a WPA2-Enterprise network in the past. I eventually got it and it required me to use wpa-configsection with netcfg that had the following:

key_mgmt=WPA-EAP
eap=PEAP
group=TKIP
pairwise=TKIP CCMP
anonymous_identity="anonymous"
priority=1
phase2="auth=MSCHAPV2"

No idea if this will help you or not!

TKIP and CCMP is probably part of the wireless_tools package (I would hope), but the MSCHAPV2, is Microsoft's password challenge, that's probably the source of the problem. The cisco routers favor MSCHAP I'm guessing. Without MSCHAP, it takes a few times, but once it takes it, I don't usually have any further problems, but it is quite cranky up to that point. Either that or the MSCHAP is handled by a Microsoft Server on the other end.

Alright, I got it to work and I'll be marking this as solved, here is my /etc/network.d/"network name"

CONNECTION='wireless'
INTERFACE='wlan0'
SECURITY='wpa-configsection'
ESSID=''
IP='dhcp'
CONFIGSECTION='
ssid=''
key_mgmt=IEEE8021X
key_mgmt=WPA_EAP
eap= PEAP TTLS TLS
identity='redacted'
password='redacted'
ca_path='/etc/sll/certs'
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"
priority=10 '

Thanks for all the help!
