I forgot to mention that my network has been working fine for years. This just happened last night. My laptop is only 2 1/2 years old.
I have a HP Pavillion tx 2000 CTO Entertainment tablet PC, running Windows Vista. My internet connection is wireless through Verizon DSL. I was online going onto a new page when all of the sudden the connection was lost. The taskbar has a red "x" through the connection icon.
What I have done:
Under Device Manager, there is nothing flagged. Everything appears to be working fine.
The LAC icon is showng "network cable unplugged". I disabled and then enabled it.
The wireless network connection icon is not there.
I downloaded updates from HP - BIOS, Network and Internet updates.
Turned off the router and back on again.
Shut my laptop down and restarted.
Hooked up an Ethernet cable to my laptop which connected me to my network, but on disconnecting it the error message came back.
My other computers have no problems.
