problem connecting to Linksys WCG200v2-CC with wpa_supplicant and ndiswrapper

whitewall · 12-23-2006

I run Gentoo Linux, and I am trying to connect by wireless to a linksys wcg200v2-cc router/modem (supplied by comcast).

I use wpa_supplicant and ndiswrapper. I can connect fine to the router via ethernet cable and I can use my wpa_supplicant/ndiswrapper wireless to connect to other AP:s (at my university, both WPA and open)

I use wep encryption on the router. Other people (in the apartment, using windows) can connect via wireless.

According to wpa_cli, wpa_supplicant authenticates and connects. What then happens is that dhcpcd waits for dhcp response, but times out. It only takes the router a couple of seconds to assign an IP adress via ethernet cable.

wpa_cli output:

<2>Trying to associate with SSID 'our network'
<2>Associated with /cut/
<2>CTRL-EVENT-CONNECTED - Connection to /cut/ completed (auth) [id=1 id_str=]
status verbose
bssid=/cut/
ssid=our network
id=1
pairwise_cipher=WEP-104
group_cipher=WEP-104
key_mgmt=NONE
wpa_state=COMPLETED

excerpts of wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
eapol_version=2
ap_scan=1

# WEP
network={
ssid="our network"
key_mgmt=NONE
wep_key1=/cut/

wep_tx_keyidx=0
priority=2
}

How should I proceed / what is wrong? Thankful for any help - (Comcast "does not support linux")

I was successful today. Woo-hoo!

Are you using the Gentoo initscripts? What does you /etc/conf.d/net look like (w/o the WEP keys)?

Two points of note:

1) At first, I used "-Dndiswrapper" on the command line for wpa_supplicant. But with any sw even remotely recent, "-Dwext" should be used. This will use the kernel's more generic API.

2) I set ap_scan=2 and, in my network block, scan_ssid=1 and auth_alg=OPEN. My router does not broadcast its SSID, so maybe yours is different, but it might be helpful to play with these parameters.

If you're paranoid, unloading and reloading the ndiswrapper module between each try might be good too.
