I had to reinstall Windows on my machine after a HDD issue forced me to get a new one. Before, I had Windows 7 Enterprise installed and could connect to my WPA-PSK secured 802.11g router fine. Post reinstall, I have Windows 7 Ultimate and after it tries to gather information from the network it says Windows was unable to connect to the network. This is not the first time this issue has occurred (last time I could not connect I had Win7Pro I believe). Any suggestions?
