I can manually connect to a wireless network, but on logout or restart the connection cannot be automatically reestablished. Troubleshooting the connection in part states that the network in not in my preferred list (or something similar to that). After a great deal of hunting, I found that the 'Manage Wireless Networks' should contain one or more wireless networks from which one chooses the preferred network which then gets automatically reconnected on logon or restart.
Unfortunately, all attempts to 'add' a network to the list fails. Two methods for adding are available: Manually create and Ad Hoc. I know I don't want Ad Hoc, so I select manually and no matter how many permutations of inputting information into the provided screen access to the network is always denied, yet providing the same information via the Network sharing center is successful.
It appears that because there is no network identified in the Manage Wireless Networks, there is no way to automatically restart the network connection.
In Vista, there was one other 'Add' possibility and that was to ADD a visible network. There is no choice in the Manage Wireless Networks ADD function for this Vista feature (at least in my Windows 7 setup). Although clearly, when I click on connect to a network I get a whole slew of choices.
If I cannot get this feature to work, I will probably be forced to go back to Vista. BTW, I installed the released Windows 7 upgrade from my Vista setup.
