[SOLVED] wifi problem

Hello,

I have slackware64-current on two laptops, with identical etc/resolv.conf, /etc/wpa_supplicant.conf, /etc/rc.d/rc.inet1.conf. But one laptop connects correctly to wifi after booting, and the other not. But it is still possible to connect using wicd. How can this happen ?

Network Manager can be temperamental with dhcp clients. I would try changing the client used from dhcpcd to dhclient and see if that fixes your problem. Network Manager seems to have issues with both clients, but usually one will work if the other won't. Pat has found the least amount of issues with dhcpcd, but it doesn't work for everyone.

If that doesn't solve your problem, please also post more information on your wireless devices, using lspci -k | grep -iA3 net.

@bassmadrigal : thank you for your answer, but I don't use networkmanager. I have tried to make /etc/rc.d/rc.networkmanager executable, but this does not change anything. lspci -k | grep -iA3 net gives

I am used to need only the simple files


wpa_supplicant.conf

GATEWAY="192.168.1.1" DEBUG_ETH_UP="no" IFNAME[4]="wlan0" USE_DHCP[4]="yes" WLAN_WPA[4]="wpa_supplicant" WLAN_WPADRIVER[4]="wext" WLAN_WPACONF[4]="/etc/wpa_supplicant.conf"

wpa_supplicant could be run in debug mode, check its options.

I didn't realize you were using wpa_supplicant directly (it isn't very common anymore as most prefer to use GUIs like Network Manager or wicd).

Have you tried running the wpa_supplicant command directly to see if it connects? This can help us determine if it is an rc.inet1.conf misconfiguration or an issue with wpa_supplicant itself. If it doesn't connect, please paste the output here.

wpa_supplicant -dd -c/etc/wpa_supplicant.conf -Dwext -iwlan0

You could also try regenerating your wpa passphrase using, well, wpa_passphrase.

wpa_passphrase your-SSID "your psk" >> /etc/wpa_supplicant.conf

I would then remove your first network entry (most of those lines aren't needed) on your existing /etc/wpa_supplicant.conf just to make sure it is connecting to the right network with the correct information.

I have tried to run wpa_supplicant directly and it gives some kind of infinite loop. The beginning is here

It is possible to connect using wicd, with the same data as in the config files in /etc. But apparently wicd does something else...

I'm curious about these lines:

wlan0: 0: 48:83:c7:2e:e6:75 ssid='Livebox-1C45' wpa_ie_len=0 rsn_ie_len=20 caps=0x11 level=-43 freq=5500 wps
wlan0: skip - no WPA/RSN proto match
wlan0: 1: 48:83:c7:2e:e6:70 ssid='Livebox-1C45' wpa_ie_len=0 rsn_ie_len=20 caps=0x11 level=-46 freq=2412 wps
wlan0: skip - no WPA/RSN proto match
wlan0: No suitable network found

Is Livebox-1C45 your network or a network provided by someone else? Based on the output, I think it is provided by someone else, since it says no WPA/RSN match. Do you have any special things going on with your wireless network (hiding SSID, MAC address filtering, etc)? Did you try the new wpa_passphrase output?

My guess is that Livebox-1C45 is the name of a of box that provides the wifi connection, rented by the french Internet provider Orange.

@Toutatis: just run "netconfig" as root, choose NetworkManager to manage your connections and be happy. No need to fiddle with all these config files.

Thank you for all your answers.

@Didier Spaier : I have started from the beginning with netconfig and it works. The two laptops are on distinct locations with not the same Liveboxes. From bassmadrigal remarks I suspect that they don't use the same protocol.
