WPC54GS locks-up my Acer (02Micro OZ9612 Cardbus controller)

    I've been surfing around the internet and this forum in order to find a solution for my problem, but haven't found anything that can help me.

    The installation of the WPC54GS card runs smoothly, and there's no problem in detecting the card.
    But then when I try to use the card, when I try to connect with it to the network, the computer freezes and I have to reboot.
    I've tried to install the card with or without the linksys software, through the windows installer, but with no difference.
    I've also tried Broadcom's driver, but with the same result.

    The Acer Aspire laptop I'm using has got an internal NW-card as well, a 802.11b card. That card works fine everytime, no problems there.
    I've tried to disable it and run the WPC54GS only, but the computer still crashes.

    Up until now, the only time the computer crashed was when I tried to connect with the WPC54GS, but as I was sitting and writing this thread (connected through the internal WiFi-module), the laptop locked-up and I had to reboot.

    The WPC54GS was installed and configured, but I wasn't trying to use it, and it made the laptop crash anyway.
    If I wasn't confused before, I am now! :cry:

    I've tried to find an updated driver for the cardbus-slot, but without any success. The cardbus-slot is an 02Micro OZ9612 Cardbus controller.
    Unfortunately I haven't got a second laptop to test the PCMCIA-card, so I can't check with another computer.
    I'm using Windows XP SP2 by the way.

    Have you people got any idea what the problem could be?
    Please help me, I'm getting desperate here! :sadbye:

    If you installed the driver, before you inserted the card, there should be no prolbem. My daughter laptop a Dell D600 has a problem with a WPC54GX card causes the laptop to freeze when the card is inserted and if your remove the card the laptop functions properly. The PCMICIA controller is the same one you have. I have two WPC54GX cards that will not work with her laptop, but will work in another computer. Go to the ACER website and apply the latest BIOS update amd any card bus updates. Go to the Linksys website and get the latest driver for your WPC54GS and install it. When you said the computer crashed ate you getting a blue screen or is the computer just freezing. The update for the card bus is not available from its manufactor, but only from the computer manufacturer. I have an open ticket with Linksys for about six months. Good luck.

    Thanks for the reply!

    Actually, the computer works fine even when the card is inserted (with the exception for that one time), it's not until I try to use the card that the computer freezes, no bluescreen, it just locks-up.
    But if I remove the card again, the computer doesn't work, I have to reboot.

    I've already tried the newest update for WPC45GS, but I'll take a look if Acer has released any new BIOS updates.
    Did you ever make your daughters Dell work with the WPC45GX card?

    Thanks again.
    btw. What do you mean by you having an open ticket with Linksys for about six months?

    I have not gotten yjr WPC54GX to work yet. Will try again next week. She is away at college. I had a live chat with Linksys and they have had no resolution of the problem. They were suppose to test the card in the same model of computer, but never did. I get emails from Linksys about once a month to confirm there is still a problem. Look at the event log and see if there are any reported problems.

    I also had a live chat with linksys, but with little result.
    I'm going to return the card and satisfy with the internal 802.11b module, I guess there's a bad incompatibility problem with the WPC54GS and the cardbus controller....

    Boy, it's a very old thread so I hope you read this and respond...

    I have a Compaq Presario 2140EA with the very same O2Micro cardbus and a WPC54G v3.

    I get the same result every time the card transmits data i.e. my laptop freezes with NO blue screen of death. Ejecting the card doesn't un-freeze the system. The card otherwise doesn't lock ths system up when inserted or anything like that.

    So, I guess we have the same problem.

    I found a strange detail though... tell me if it's the same with you: the laptop only freezes when running on batteries! If it's connected to the AC power plug there's no lock-up... :eek:

    Please try it if you read it, I'd like to know if this issue is reproducible on all O2Micro cardbuses.

    Moreover, if any of my dear readers has any idea about why this is happening and how I can fix it (disable power management??) please do say so! :bow:

    Check to see if you have power saving enabled on the advance setting of the NIC. If you do, disable it. As for my problem there is a problem between the WRT54GX v1.0 and the O2Micro cardbus. Linksys claims it is a interrupt conflict, but under WIndows XP you have not contro over the interrupts assigned. The WPC54GX4 does not have the problem I updated the cardbus driver to the latest one dated 12/05/2005, but it did not solve the problem.

    Yeah, an old thread indeed. I actually sold my card and use the internal 802.11b wi-fi adapter instead...the linksys adapter just wouldn't work.

    I tested running both with and without AC power, and it locked up both times. :thumbdown:

    Apart from that it seems like we have the same problem.
    Good luck solving it! :thumb:

    Thank you for your reply. Of course you had to sell your card, especially when you have internal wi-fi! (Another little thing we have in common is that my Compaq uses the same chipset Acer computers use).
    I'll try to solve this thing (especially because I don't have an insternal wi-fi) but I don't feel confident anymore!

    Unfortunately, power save was already disabled on the WPC54G by default. I've also tried to set Windows' Power Management to "always ON" but with no difference.
    I've also talked extensively with HP/Compaq support specialists and took steps from chipset drivers update to Windows' Power Management re-installation... nothing worked :cry:

    You mentioned that you updated the O2Micro cardbus drivers. Could you please tell me how/where because I've searched all over the net for a new driver but I can't find anything!

    Dell had a updated O2Micro cardbus driver. It is not available for the producter of the adapter, but you have to get if from the laptop manufacturer. If you cannot get it, contact me.

    Thanks howardp6 for the info.

    As you suggested I found the driver from Dell's support page indeed (though not from the D610 page but from another model's because I have the OZ9612 cardbus).

    Unfortunately, the driver installs but isn't accepted by Windows as a valid one: the system reports that the .inf file "does not contain information about your device".

    ...hmmm... I'm running out of ideas here... :sadbye:

    I know the WPC4GX4 costs more. You can get at at Bestbuy for $79.99 until Sunday, than the WPC54GS, but it works. See if you can return the WPC54GS. The driver for the cardbus adpater did not solve the problem om my Dell D600, so it does not help.

    I'll try to return the wi-fi card then but I don't think they'll accept it because it's not the card's fault (return policy is limited in my country).

  14. howardp6

    howardp6 Network Guru Member

    It is a conflict between the cardbus adapter and the card. You are exchanging the card. If they will not exchange the card contact Linksys, maybe they will exchange the card for you.

    As it was expected, the shop didn't accept the wi-fi card... :thumbdown:

    They made me get my notebook to show them the problem and then produced a brand new laptop (the owner's personal one) and tried the card on it: since in worked fine, they concluded that it was my notebooks fault, not the card's.

    They suggested something very interesting though: it might not be a conflict but an inability of the cardbus to supply adequate power to the wi-fi when running on batteries. (I need to borrow another card to test this hypothesis)

    I am not a fan of USB wireless NIC, will the shop exchange the WPC54G for a WUSB54G. See if you can test the USB card,. May be the shop will let you exchange the WPC54G for an internal minicard, if the Compaq can accept a minicard.

    I don't like USB wi-fi either, because this notebook only has USB 1.0 :)

    But I'm going to check the specifications about support for minicards! Thank you, you've been more helpfull than most PC technicians I've talked with! :thumb:

    I cannot comment on your problem because it's different from mine: my laptop only hangs when on battery power but runs fine on AC for days in a row. It's been suggested that my notebook fails to provide adequate power to the smartcard adapter when on batteries. I'm waiting for a mini-PCI to bypass this limitation but it hasn't been delivered yet and that's why I haven't posted any updates on this thread.

    But hey, look at the bright side: at least you know for certain that a wi-fi adapter works on your machine! You can even trade your Linksys for your friend's D-Link et voila! :grin:
