How to add a HP Pavilion DV4000 to a wireless network?I already have two computers (Vista) running on the network, this HP has XP?

athr.sys = the driver for the Atheros wireless network card. You must update it.

You are using a B wireless adater on windows XP computer.
Tere might be adapter utility installed on your computer. You can use that software to connect to the wireless network or you can switch over to windows software to connect.
It will be better if you use the WINDOWS XP to connect to the network.
Check the wireless settings of the router also.

Windows WiFi Fix,
Windows Zero Wireless Configuration is one of the best programs to run a WiFi in Windows XP or Vista. Most of the other software packages that come with the different adapters have been poor at best in keeping a connection through Windows. Here is the best guide to get you back up and connected.
Windows XP:
Click Start
Right click on My Computer
When a window pops up click on properties
Click on the Hardware tab
Click Device Manager
Click the [+] next to Network Adapters
Find your wireless card and right click on it.
Click Disable
Windows may warn you that disabling the device may make it stop functioning.
Continue disabling the device.
Wait 30 seconds or so.
Right click on your wireless again and click Enable.
Exit the device manager.
Reconnect to your router.
You should now be able to connect to the internet.

Windows Vista:

Click Start Logo
Right Click Computer
Click Device Manager
Windows will ask you about opening Device Manager Click Continue
Click the [+] next to Network Adapters
Find your wireless card and right click on it.
Click Disable
Windows may warn you that disabling the device may make it stop functioning.
Continue disabling the device.
Wait 30 seconds or so.
Right click on your wireless again and click Enable.
Exit the device manager.
Reconnect to your router.
You should now be able to connect to the internet.

here you wil find all the drivers for Xp...

You can download drivers from HP's website. They list 77 models in the dv4000 series. Click here for the list, pick your particular model, then choose your operating system. You can then download the drivers you need for your computer.

Is your chipset wireless network program taking over?
Often an internal system program will take priority when connecting to wireless networks.
Think of it like siblings who squabble over attention.

If you can find any other programs which are acting in this manner, I'd suggest telling them "do not use this when connecting" and then see if you can then use your main program.

Also - is your network secured and / or hidden? Did you reset your router? Sometimes this helps, too. =D

the drivers needed updating, got to love Windows.
