I did a clean install of Windows 7 Home Premium (64 Bit) on the main desktop in my hous. I have 3 different versions of Windows here. 1 for the desktop and 2 for 2 laptops. Everything went exellently until it came time to setup the wireless connection. I did not change a SINGLE thing from Vista. So I entered in the passphrase that I always entered in when my computer were running Vista. The same passphrase/password I gave to visitors who would bring over their phones and need to access wifi. However it keeps/kept saying, "The network security key is not correct" When I put the mouse over our networks name it says that it is WEP. When I try to do it manually and select "WPA" and "AES" encryption 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.
