WLAN "disappeared from system"

HP Pavillion dv6000 laptop-

Each time I lose my internet connection I get the error on event
viewer;
"The device 'Broadcom 802.11b/g WLAN'
(PCI\VEN_14E4&DEV_4311&SUBSYS_1363103C&REV_01\4&14 c5f9b7&0&0018)
disappeared from the system without first being prepared for removal."

A reboot restores it- but only for a minute or so. It seems like if
I shut things down for a long time it stays connected longer-- but it
is unpredictable.

I am suspecting a hardware problem--- but wonder if a memory or IRQ
problem is possible.

The WLAN device is currently using IRQ 22 & device manager shows no
conflicts but IRQ 22 is also used by
"Standard OpenHCD USB Host Controller" Disabling this device makes no
difference.

If it is a hardware problem, then it is on warranty-- but I'd like to
prove that before I start with HP support.

Any thoughts?

Thanks,
Jim

What operating system?
What maker and model wireless card are you using?
Built in MiniPCI or USB?
Driver version (if you can find it)?

That smells like overheating. Depending on what you have for a
wireless device, I suspect it's dead or dying.

Another possiblity is that it's just not shoved into the MiniPCI
socket correctly. Open lid, wiggle card, close lid, and try again.

Another possibility is tat your USB port is shutting down, going to
sleep, or turning off for some reason. Anything plugged into it
proclaims itself as disconnected. Look into the power management
settings. Also, your unspecified USB device might have a setting for
something like "let Windoze control the power".

Work on disclosing what hardware and software you're using so I don't
have to guess.

Hi,

Built in- factory - I thought "Broadcom 802.11b/g WLAN" identified
the card- that driver is version 4.100.15.5

Under Network adapters I also have "1394 Net Adapter" driver version
5.1.2535.0 [this shows as working even when I lose connectivity]

and NVIDIA nForce networking controller driver version 50.2.4.0

I hadn't ever looked in there- so I popped off the two access covers
on the laptop. 1 has the memory- the other the hard drive. Couldn't
see anything else under either- so I left well enough alone. If it
looks like hardware I'll deliver it for warranty work.

No USB devices involved. Power saving turned off. [except for hard
drive after 2 hours or some such] Also it is pretty random.
Sometimes only allows a minute before disconnecting- other times an
hour or two.

I think I covered the hardware. For software-
This might be significant- It *seems* like if I just open Agent 4.2
[Forte's email & usenet client] I keep connected longer than if I open
IE7 & start browsing the internet.

I use AVG free for virus control- and haven't caught anything. It
updates daily.
AVG Anti-spyware 7.5
Windows firewall.

I think that's it--
Thanks,
Jim

What's that? Is it Windoze ME? Are you sure it's not Windoze XP or

Right click on "My Computer" icon and hit "Properties".
What operating system does it say? What version?

That's the MiniPCI internal wireless card. If you have XP, I think
the current version is 4.40.19.0. However, I'm not sure. See:
<http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-41607-1&lc=en&cc=us&dlc=en&product=1842155&os=228&lang=e n>
Since I'm NOT sure what exact model you have, I can't tell if this is
really the latest driver. Use the "HP Update" wizard. There's also
the HP Wireless assistant to update:

That's your firewire port. It's not involved in this problem.

>and NVIDIA nForce networking controller driver version 50.2.4.0

That's your ethernet port. It's not involved in this problem.

Look again under the middle cover. Here's the instructions on how to
replace the wireless card:

Argh, a flash video clip. Looks like an Express PCI card.

That eliminates power saving, but I'm still suspicious. See if this
sounds familiar.

Not really, but it's not your fault. HP dv6000 has many variations.
See if you can determine exactly which is yours.

Only 48 models to choose from.

Weird. I have no idea what that means. If it's a power down problem,
as I've been suspecting, then the traffic generated would keep the
connection up longer with whichever program generates the most
traffic. Try firing up IE7 and play a *LONG* YouTube video clip. Does
it stay up?

I don't think this is a virus or spyware.

Media Centre Edition (a version of XP that MS tried to use to break
into the 'a pc in your living room' market).

Nasty echo in here.

The HP tag on the back says
"Product HP Pavillion dv6000" - I checked their support page when I go
there it also identifies it only as a dv6000.

Then I found this
"Many HP Notebooks are identified by a series number rather than the
actual model number. For example, the notebook PC may be labeled with
dv9000 on the case, but it is actually part of a 9000 series notebook
PC. The correct model number may be dv9098" Then they show how to
decipher the product tag-

It's a dv6171cl. Did they manage to make that as difficult as
possible?

Media Center Edition-- sorry I just went to Win98 [from WFWG] a couple
years ago- and have only used this laptop for a couple months. I
thought MCE was a common abbreviation.

>Right click on "My Computer" icon and hit "Properties".

Windows XP
Media Center Edition
Version 2002
SP 2
[but I note that the MS authentication tag on the computer calls it
'Version 2005']

You are correct on the driver version. I just ran the 'HP
update wizard' a week ago and it said I was good. Next time I'll
look for whatever is giving me trouble and do it manually.

Ahhh-- and a huge one. But worth 10,000 words. Turns out I
probably did what you suggested without realizing it. I was looking
at the cable connections because they were unfamiliar to me, and
wiggled them on their contacts to see how they worked.

And I've been connected now- with both Agent and IE7 for several
hours. [that was a couple days ago- yesterday was flakey again]

Thanks for that link-- lots of other good clips there, too.

Not really- If I understand it correctly, when I close the laptop it
goes straight to hibernation. It always restores when I return.
OTOH- someone there mentioned the unreliability of HP Update vs
Windows update-- I'm waiting for Windows update to load as I write
this.

Started R. Kelly's "Trapped in the Closet" 41min. at 8:18am- finished
loading about 8:40 - and it played through. [this might be another
'good day' - I've been online for over na hour with no drops.]

-snip-

Thanks- even if it isn't really cured you've given me a wealth of
info and sources.

Since it seemed like wiggling those wires cured it- but only for a
day. . .and now it seems ok- Do I dare put the tiniest drop of
dielectric grease on them-- or just hit them with some desgreaser?

Hibernation? That sounds more like suspend to RAM. Hibernation is
where the contents of RAM are written to hard disk, and read back in to
restart, which typically takes a noticeable amount of time. Suspend to
RAM is instant by comparison. Regardless, neither has anything to do
with power management.

Yikes! Use contact cleaner (sparingly) instead. Available at Radio
Shack.
