[SOLVED] Networkmanager does not connect to WEP without key

jlinkels · 07-13-2011, 07:38 PM

I am running KDE4 on Debian Squeeze.
Networkmanager works fine, for both WEP and WPA. Connects automatically etc, no problem.

The only problem exists when I want to connect to a WEP network which has an empty security key.

I used to be able to connect before I used networkmanager using iwconfig and specify iwconfig wlan0 key off

I tried in networkmanager to specify both no security and WEP with an empty passkey. However, none works.

Is there maybe somewhere a setting which precludes connecting because it is considered unsafe?

WEP? No key? What's the difference? WEP is so insecure. Either have an open network or at least use WPA.

It is the airport network and I have no influence as how it is configured.

wow, note to the world: DO NOT CONNECT TO AIRPORT WIFI... Although even the basic networking student could have figured that out.

steps to follow:

fire network engineers @ airport
or @ least change to wpa with ap isolation.

You might try using kwalletmanager to edit a wep key entry for this network. Try entering "" as the value.

I don't use wep, so I edited the psk= entry for my home network, adding quotes around the password. I then disconnected from the network, and it reconnected automatically. My hope is that empty quotes are read in as a null string, instead of an empty field, causing a prompt for a passphrase.

jschiwal, I store the settings and passwords for networkmanager unencrypted. However, altough I am able to find all my connections in networkmanagerrc, I didn't find any passwords here. The passwords are available in knetworkamanagerrc, but I think this is an outdated file from the previous KDE installation. It has a timestamp from the that I upgraded from KDE3.

Any idea where networkmanager stores it unencrypted passwords nowadays? I googled for it, but no answer. Passwords are stored.

Weird. I was at that airport again last week. In networkmanager I deleted the access point, had it rediscovered and activated it without security. It connected.

So it seems a problem with the management of the connection, rather that a real problem with the connection.
