DLink DWL-G630 connects intermittently

  1. I am having problems getting a wireless network to work...

    I have a Panasonic Toughbook CF-R1 laptop running Windows XP SP3 with a
    Dlink DWL-G630 wireless interface, using the "Marvell Libertas
    802.11b/g Wireless" drivers.

    It will only connect intermittently using WPA to our SMC2804WBRP-G
    wireless router. On unsecured network using this router and public
    hotspots t connects without problems.

    I have been testing the connection using ping to other devices on the

    2 other computers (running Linux) have no problems connecting

    Windows firewall is disabled. and no other firewalls are present

  3. Hi
    Is the Router's SSID is broadcasting?
    Some computers can work OK with SSID Off some cannot.

  4. Yes, and confirmed using airodump-ng.

  5. Both are set to WPA-PSK with TKIP, IP addresses are setup with a DHCP
    server that works with wired connections.
    Running wireshark on the laptop in question reveals several EAPOL key
    packets are being received, but are not replied to; unlike the working
    Linux system.

    I have recorded some log files:

    Have you ever considered check your anti-virus or "enhanced" Internet
    security softwares? I experienced a similar problem when I was using
    Norton 360 security software. I needed to tell the software to trust
    the wireless SSID within the firewall module.

  7. It currently has Avast Home installed, and previously had AVG Free Edition
    installed. Neither claims to be a firewall or has any relevant options.

    Try to change the transmission channels in the Router and see if another
    channel provides better results.
    If it does not help try another (newer) Wireless Router on the same

  9. After install later drivers it now works, these drivers seem to be a poorly
    kept secret.

    The drivers on the Dlink website for a DWL-G630 are, according to the Update
    Driver Wizard for a different device.

    The Marvell website wasn't helpful.

    Windows update didn't offer them.

    However a google search for the vendor and device IDs lead me via
    driveragent.com to:

    Hi Timothy

    I downloaded driveragent and tried it. I am trying to determine if there is
    a better drive for my router (TRENDNET TEW-432BRP) to which I am connected
    by wireless. The router did not show up on the Driveragent report. Does
    driveragent work on routers too?
