Wireless Network NO GO!

Dear Group,

Hi, I got a friend's HP DV 9005US laptop / notebook, with a wireless
adapter that don't work reliably. Its an intermittent issue, according to
my friend, it worked for a long time, then stopped, I downloaded and
flashed the BIOS it worked, then I was ready to return the laptop did a
double check not the network card does not work again! I flash the BIOS from Hp's Official Website, with the appropriate driver and bios flash, and still NO GO! I sent an email to HP about this issue, to see if they can fix it also seems to get very hot, and the red light is still on. Please? Help? I also checked the switch on the front, both ways to
the little symbol on the outside and away from it, and still don't work.

    Dear Ruben,

    Hey, you know, I double checked and verified the
    s/n, and p/n, and the info on the laptop, and the
    warranty expired! :p I sent emails to HP support and
    since the laptop is expired based on the s/n, and p/n, more than likely it will be better to get a PCMCIA or wireless connect card, and let the onboard wireless go. What's funny, is that I'm responding on a Fujitsu laptop for $150 bucks! I ended up tearing
    it down, after a friend at my workplace taught me
    how to 'strip it' and 'strip it good' lol, I did
    replace the CMOS battery after I let the Fujitsu N
    Series, Lifebook 3430 system discharge for a few
    days, put it together a few times then got it right!
    Knock on all kinds of wood, holding together like a
    champ! :) YOU GUY's ROCK! MAJOR KUDOS!! KUDOS and a
    Heck YA, FIX YA to everyone who helped me out! :)
    I'll have to convince my friend to get a wireless
    connect card or PCMCIA slot.. and go from there.

This is a known issue with these models, its the motherboard. it will have to be replaced. this will not go away with bios updates. here is the link to submit your information to get them to send you a box and get a new mobo put in. time is of the essence they are shutting down this opportunity in november i believe..

btw it is a free repair but you will need the information of the original owner when you call

good luck!

    bios flash is a must on these systems. there have been changes to the unit software that hp has set into motion to attempt to prevent the underlying motherboard issues. installing a pcmcia card for networking use will not resolve the internal issues with the design and overheating of the issues. this is a known issue with these motherboards that requires the GPU chips to be reflowed or reballed. The wifi will go out first, then the charging components that recognize the battery and so on...i have dealt with this issue a great deal. i ship about 25 units a month out with this issue.

    Good Luck!

Just as far as the heating issue goes, you may want to invest in a cooling station for it. They work great! You'll notice a huge performance change.

As for the wireless, I would maybe try investing in a PCMCIA card and see if wireless works on that. That's only a suggestion if you are tired of dealing with it and would like a quicker fix. I would recommend trying to reinstall the drivers for the wireless adapter itself instead of flashing your BIOS.

This is just an example of what you'll be looking for if you do decide to go that route.

HP 530 wireless will not pick up any wireless networks. Please help


First ensure that the wireless adapter is turned on.

If the adapter is on and does not detect any network, reinstall wireless network adapter drivers. the drivers can be obtained using the link below.

Download drivers and software

Reinstalling driver software usually fixes the problem, if it does not it usually means that the internal adapter is defective, in that case you will need to use an external wireless adapter (USB).

Hi. Please check first if your computer was able to detect the device. You can look for this device in control panel then click system then click device manager. Your wireless adapter should be present under network adapters. f computer was able to detect the wireless adapter. Try to turn off/on the wireless switch. Usually, wireless switch is located infront of the laptop or on the side. You can also try pressing Fn + F5 key to disable/enable wireless network card.

Hi, we have a toshiba S1800-254 computer and need to make it wireless, so we were wondering what card to use what to do with it and where we can we buy one ?

Seeing as how its an older laptop, your best option would be to get a wireless USB G network adapter, it plugs into a USB port on your laptop, then get a wireless G router to match up with your wireless G Network USB adapter. Stick with Belkin if you can since they have been reliable from my own experience. Get a Belkin Wireless G Router and a Belkin wireless G USB Network Adapter. At that point you'll have wireless access and it will run you under $100 dollars.

hi Vince,
Try this, Go to Control Panel->System->Hardware Tab->Device Manager. Select Intel Pro under Network Adapters. Right Click and Select Properties. Under the Advanced tab, there is a setting for Power Management. On Windows XP, this is a slider with Max Battery on one end and Max performance on the other.

If that don't work, there are several more solutions here,
