Hello,

We are having some difficulties with our older Compaq/HP laptops.

Our issue is that if you deactivate the device in the Network Connections window, we are unable to activate the device again unless we install the HP software and then choose activate here.

We also have a second issue, if the computers start up on battery, the wireless adapter is turned off and we are unable to activate it again using the external button(or internal in the OS) without plugging in the powercord and rebooting.

Any ideas on how I might solve these issues?
ATM they are currently affecting 20+ computers.

Hi,
Second issue might be related to Power Saving settings of your laptop.
Open Properties window of your WLAN adapter, Switch to "Power Management" tab and uncheck option "Allow the computer to turn off this device". Apply changes, OK to all open windows.

First issue: I suggest drivers update for WLAN, system update for windows.

Frst issue: Open "Network Connections", right click WLAN --> Properties. Switch to "Wireless networks" tab, CHECK "use windows to configure wireless networks". Apply, OK to all opened windows.

This will allow full control of your WLAN nic by windows resources.

I understand that, but we dont want to pollute our computers with HP's software.
Is there any way to figure out what the software does and mimic that?
I think it will be too hard to install the HP software, activate the WLAN card then give ownership back to Windows. If the WLAN card then gets deactivated, one needs to activate in HP software again, then deactive its ownership, all over.
How will the user permissions like the HP software? With printers its very bad and you cant even use "Run As...".

Sadly its not the Pavillion or Pressario series, good read tho, will investigate if doing a BIOS upgrade will work.

Any other ideas?

I found the solution, the problem was that the installation image was made on a newer PC with newer everything and didnt like the downgrade as much.

I found the issue, it was related to HAL.
If I downgraded the HAL on the computers, the issue got solved.
