HP Pavillion dv6000 laptop-
What operating system?
What maker and model wireless card are you using?
Built in MiniPCI or USB?
Driver version (if you can find it)?
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&14c5f9b7&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.
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.
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.
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".
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?
Work on disclosing what hardware and software you're using so I don't
have to guess.
Thanks,
Jim
