Connecting with WPA

bb002 · 09-29-2005, 10:19 AM

I am using Ubuntu 5.04 and a Gateway M275. Ubuntu automatically detected all of the hardware except the tablet(no biggie hardly use ti much anyways).

I need to be able to connect to two WPA enabled networks.

My home network is WPA-PSK with TKIP and the SSID is not broadcasted.
At work the network is WPA-PSK with TKIP and the SSID is broadcasted. My work has multiple APs setup for roaming.

When I run wpa_supplicant at home it sees an AP with a hidden SSID but won't associate.
When run it at work the APs are found and association is attempted. It failed because it tries to accociate with to an AP the has a MAC of all zeros.

I followed the guide I found on ubuntu's website but it didn't provide much on diagnosing problems. I've dug around for awhile and have progressed from wpa_supplicant doing nothing to seeing aps to it finally connecting to a bad ap. I need some help. That dark corner is looking nice and cozy right now...

wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant

ap_scan=0

network={
	ssid="myhomefakessid"
	proto=WPA
	key_mgmt=WPA-PSK
	pairwise=TKIP
	psk="whatsthepassagain"
}

network={
	ssid="lameworkssid"
	proto=WPA
	key_mgmt=WPA-PSK
	pairwise=TKIP
	psk="ikneedthisonetoo"
}

wpa_supplicant console output

Code:

Try enabling the ESSID broadcast of your AP and then connect to it using WPA. I never had any luck in associating to hidden AP's using WPA.

At work the SSID is broadcasted. And that's where I'm trying to connect, seems I forgot to mention that is where the console log is from. once I can connect at work i'll figure out something for home. I use my laptop at work most of the time anyway. I only mentioned my home network because it's in the wpa_supplicant.conf file, I normally wire-up at home.

I finally got wpa working. it appears that the "ipw" driver that comes with ubuntu 5.04 doesn't support wpa. however the current version does. so i manually compiled and updated the "ipw" driver since it wasn't listed. and if it was i missed it.

Now at work it connects and work perfects....almost. Home still has a few issues but i can eventually connect. maybe someone has a pointer or two to help me.

New /etc/wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant

#ap_scan=2

network={
       ssid="fakehomessid"
       scan_ssid=0
       proto=WPA
       key_mgmt=WPA-PSK
       psk="supersecurepass"
}


network={
       ssid="ssidatwork"
       scan_ssid=0
       proto=WPA
       key_mgmt=WPA-PSK
       psk="superinsecurepass"
}

Work connects without a hitch. Home however requires a bit of trickory. Home has a hidden ssid but make scan_ssid=1 doesn't work. inorder to make it work i have to uncomment the ap_scan=2 then run wpa_supplicant, terminate wpa_supplicant, comment ap_scan=2 out again then run wpa_supplicant one more time. Now i can connect at home.

What I want to know is why must I do this to connect at home!? if i enable ssid broadcast it works fine, no trickory, no nothing. It just connects like work. disable ssid broadcast and i have to go through all of that again.
