Hello there,
I really hope you can help me with this problem as I've been dealing with it for the last 2 weeks and have become hopeless...
My brother recently had problems with his internet, so he gave it to me to solve the problem.
His laptop is an HP Pavillion dv9005us with Windows XP SP2.
The first time i looked at the laptop, I noticed that there was no connect-to menu in the start menu, and that there was no wireless network connection icon in the right-bottom corner. So I looked up which wireless network adapter he was using, and it comes actually in the laptop, but the device manager did not show any missing network device, neither did it show any network device (other than the1394 net adapter). The missing device is a Broadcom 802.11 Wireless Network Adapter. I had no idea what happened, but I downloaded the network adapter driver setup from hp's support website, and used that. It did not work, so I decided to reformat the PC.
After I formated the harddrive and reinstalled Windows XP I also reinstalled the network driver, and it worked. However, after I shut down and turned on the laptop, it didn't appear again! Same problem as before, the PC does not detect the wireless network adapter. Then again I shutdown and turned on the PC and it worked again. So I formated everything again, but the problem remained. So the only other thing I checked was the BIOS. When the system boots, I pressed F10 and checked all the options and noticed that in the boot order menu the network adapter had an exclamation mark next to it, still there was no explanation on what the meaning was.
I really hope you can help me out, because my brother really needs the wireless internet for university
