Just to update you....
That "unknown device" turned out to be the printer I'm pretty sure. I forgot that I had it plugged in from before I clean installed Windows 7. I unplugged the usb cable of the printer. Took it off completely, waited a few secs, then turned it back on, and plugged it back in. The drivers were installed automatically by Windows 7 and it recognizes it when I go to "Devices and Printers".
Also I did a clean install of Windows 7 Home Premium (I have 3 different versions of Windows here. 1 for the desktop and 2 for 2 laptops).
The SAME issue is occuring with the wireless network. When I put the mouse over our networks name it says that it is WEP. When I try to do it manually trhu the network and sharing center it gives me this message...
"The settings saved on this computer do match the requirements of the network."
And there is a big red x mark to the right of it. However it doesn't give me the option to disconnect from the network. To remove it and start over I have to go to "manage wireless networks" and remove it completely.
So to summarize. When I have my wireless security:
1) DISABLED ---> I can connect wirelessly just fine.
2) WEP ---> Connects wireless with no issues. I just have to enter the key generated from the "passphrase"
3) WPA-Personal ---> CANNOT CONNECT WIRELESSLY. No matter what I try. I've tried entering the passphrase a million times. Still doesn't work. I've tried entering the router login password. That results in "limited connectivity". I've tried resetting the router. Didn't do anything. And finally I've tried changing the properties of the connection in Windows 7 (see above).
I'm trying to download the drivers from
HP's website but I keep get an error message.
