    ipw3945 drops connection


    Hi,

    I'm using openSuSE 10.2 on my Dell E1505 laptop. From the beginning I've had problems with WiFi. While high bandwidth usage (for example when downloading or copying data from local hard drives)The WiFi LED starts to blink and then it drops connection with the wireless router but when I'm only browsing the web the problem doesn't occur. When I use Windows there is no such problem - the connection is stable. After each reconnection I have to enter the encryption key once again. It's really annoying. I'm using kernel 2.6.18.8-0.3-default with generic ipw3945 drivers. While running iwconfig I get:
    Code:
    linux:/home/matt # iwconfig eth1
    eth1      IEEE 802.11g  ESSID:"Wireless-G Router"

    Thanks in advance for any help.

    Having the same problems

    I am having the same problems on openSUSE 10.2.
    NetworkManager usually sees the network I want to connect to, but cannot connect and asks for password over and over.
    While the password prompt dialog is open, I run:

    iwconfig eth1 mode Ad-hoc
    iwconfig eth1 mode Managed
    dhclient eth1

    which fixes the problem.
    After suspend/resume, the card usually doesn't work any more and needs a restart. I will post debug output later.

    There is a package called pam_keyring you can install from the packman repositories. You can then configure NetworkManager to read your details from your keyring automatically. Net connections will be automatic then. There are three points to note -
    • Your keyring password should be the same as your login password
    • This doesn't work if your system is set to automatically login (i.e. without you entering a password)
    • This is for GDM/Gnome


    If any of you guys are interested I can post the /etc/pam.d/gdm file which is required by pam_keyring.

    If it's any good to you guys here's the modified pam.d/gdm file you would need -
    Code:
    #&#37;PAM-1.0
    auth     optional       pam_keyring.so try_first_pass
    auth     include        common-auth
    account  include        common-account

    Thanks for Your support, but loosing the password isn't the major problem - the fact of dropping connection is. Knetworkmanager is using kwallet to store passwords.When linking for the first time in each session the password is given correctly, but is not given correctly after dropping connection. While using traditional connection manager - ifup the password problem doesn't exist, but the association to the wireless network is still dropping. I'm wondering rather is this a problem with ipw3945 drivers, ieee802.11 subsystem or with wpa supplicant?

    I'm having the exact same problem. Same laptop, wireless card, and also running opensuse 10.2. Is there a fix yet?

    I have this same network card in my laptop.

    I have never had this problem, but just wanted to point out its definitely an openSUSE problem. I have had this wireless card running in slackware 11 and 12, ubuntu 6.06. kubuntu 6.06, and vector linux without issue.

    just my $0.02, and best of luck finding a solution.
