HELP! wireless problems

Hello,
Its been a while sence i have been to AO but i have been having some computer issues that i cant figure out on my own... I dont know if this fits under security but i hope you can help.

The issue is that whenever i connect to a wireless network (no matter the place) my computer nearly instantly bogs down to the point i can hardly move the mouse and it says the CPU is running at near 100% with nothing showing as the power hungry problem. As soon as i turn off the wireless or disconnnect it goes back to normal no problems.


Any suggestions... please Im on a hard-line without that problem so i am baffled but in need of repairing.

Help...

Though I don't know much about the topic at hand here, I'm sure you'd be likely to get more help if you told us more about your system e.g. what wireless card are you using et cetera?

ok.. unfortunitly i cant give you to many details i have an HP Pavilion dv8110us. It has a built in basic 54g™ 802.11b/g WLAN with 125HSM. I have never had a problem before with it before. If anyone has any idea of anything to even try id be happy to hear it.

Have you updated the drivers recently?

I assume that you are running Windows XP?.................you might try a repair install?

EDIT: What happens if you try to boot into safe mode with network support?

I have at first i hadnt installed any new drivers before i started having the problem but sence i have tried repairing the connection and installing new drivers/ updating.
I have not tried in safe mode yet but i will try that in a second.

Certainly sounds like a bogus driver/app to me. What you can do is run a process explorer to see which process(es) are spiking the CPU. This will give you a place to start looking for the problem. Have you tried throwing in a PC card and disabling your interal wireless nic? Again, this will narrow down the issue though I'm pretty sure you're going to find the issue with the HP drivers and/or their wireless manager application.

Yea ive tried that and thats what first started really confusing me. There shows nothing out of the system will show the idle process running at over 90% the same time the CPU is running at 100% so something isnt showing.

yea i am going to grab an external one from a friend but i dont have one i can use right away but thats the next step im planning. As far as the drivers, ive tried 3 different drivers and rolling back to the origional hasnt done the trick.

I also have tried to start in safe mode and found no difference in the way it acted..

Thanks for your helps so far guys

What about the wireless card manager tool? Have you updated that?

Process explorer lets you drill down within generic process names. Try that tool out.

Well, if anyone is interested in the stock specs on this system:
http://h10025.www1.hp.com/ewfrf/wc/d...dlc=en&lang=en

These appear to be the stock NICs-
-Integrated 10/100BASE-T Ethernet LAN (RJ-45 connector)
-54g™ 802.11b/g WLAN with 125HSM / SpeedBooster support

swizeguy,
I looked all over HP's site and found nothing relating to this issue. I'm curious about the router settings that your wireless card is trying to connect to. Do you know how your router is setup?

I tried the ProcessExplorer. As soon as I turned on the wireless it said that hardware interupts was the cause of the CPU spiking. Wouldnt give me any more information than that.

As far as the router.
The router i am using right now is running on all default settings. Its a Linksys 2.4 ghz broadband wireless router with a basic WPA key for some security. I dont think there is any problem with the router because all other computers when running on it do not have the same problem. Plus i have had the problem in other places other than just at my house.

Thanks for posting the specs too i should have done that.

You might try this:

It might work for you?

;)

Thanks guys.
I spent a while speaking with the HP help people. They came to the determination that my wireless card itself had something wrong with it. I am planning on trying one that a friend has to double check. My warrentee is good until the 5th on jan. They set up something for me to send in my notebook but I need it for my schooling/etc.
My new question, is it really worth going through all the trouble to send it out especially if i can just get an external card?



Thanks again for all of your help!

Well, I would say "yes" given that you have already paid for it and it is under warranty.

Now, if the "new" card has the same problems, that would suggest that it is not hardware, particularly if an external card (with a different driver) might work.

The case where DMA mode has reverted to PIO mode is a known problem. It is difficult to troubleshoot as you just get the general "hardware interrupt" warning, rather than something specific.

What is the process? send them your entire notebook and then wait 3 weeks for a turn around? I haven't dealt with HP repair since the Compaq buyout if that tells you anything.

Anyway, if they think it's the wireless card, I'm assuming you can remove the cover on the bottom of the lappy and remove the wireless card and send that in for a replacement. Seems cheaper and more reasonable for the user.

Hmmm, I see...................

It seems to me that HP are "fishing", in that they really don't know what the exact problem is. I have some sympathy for them, as I know it is not easy trying to give remote support, particularly from thousands of miles away, as in my case :D

I would imagine that they want the machine "on the bench" where they have the people and the kit to do a thorough investigation. I am sure that they will fix whatever they find.................... just sending a replacement component won't be anything like as thorough...........there could be a variety of "nasties" just waiting to happen?

If the device is going to be away for a while, I would first look at borrowing a replacement, if at all possible.

Yea whats scaring me is the fact that the thing is only under warentee for less than a week more by the time they ship me the crate to send it back it not going to even be under warrentee. Im a little paranoid where as my friend sent his HP laptop in a few months ago they sent it back with a cracked LCD saying that it was his fault.
Im going to be able to try the external tomorrow. I think ive decided against sending it away (just to paranoid). If he external doesnt work than im going to have to but if it does ill just use that.

Well, I suppose it depends on where you live?

Our consumer laws say that if you have reported the defect within the warranty period then you are covered. You obviously have a RTB instruction from them as well?

I would save my data and send it back............... but that is just me :)
