One of two HP laptops connects to network but quit on Internet

first check the bios settings if wifi or lan disabled, enable them

Hello
Wow youve done almost everything here.How about the firewall? is it blocking any connections?

Next,Go to control panel,network and sharing center.Look and see if the pc or laptop in question is on the same network,meaning home or public.

Set all your machines to the same network.Either home or public.I do know this has been a win 7 problem.

Check the IP address on the Vista wireless network connection. Make sure that there is not static IP address on the wireless connection. That could be one of the reason.

That laptop has a known issue with the wireless network card not being recoginzed by windows. You can verify this by going into the device manager and seeing if the wireless network card is in there, more then likely it won't be.

Best option is to call HP Tech support and ask them about that known issue and see if your laptop can be covered by there recall. You have so much time before the recall won't cover your laptop.

Here is there tech support number: 800-474-6836

They are open 24/7

I remember that HP computers or laptops have a 1 year warranty unless you get an extended one and recalls can last up to about a year after the warranty expires, call and see if they can get your laptop covered under the recall.

The drivers you installed may have started a driver conflict, uninstall the web cam drivers,, if that dont work reinstall the wireless drivers

check the IP address of your system.

ok..try to recycle the power for the network modem and router..then turn on the router first, let it stabilize, then turn the modem back on.

Try manually add the network. If the problems continue, I would turn the laptop in for repair/replacement (if it under warranty).

sounds like your comp did its own system restore on you and the file needed to keep parameters of modem connection disapeared
you need to go into control panel network set up wizard follow instructions this should set your network back up
do you have the driver disks for the ether net card reinstall ether net card drivers
never setup network threw internet explorer these ways dont hold

Re-check your network connections, then tick allow other computers to connect using the same network...it will work
