I have been using my home ADSL and when I had problems with it, switched to my iPhone for network access. This mostly works as planned, but I have noticed that Windows 7 creates a new network name even though the hardware has not changed; I am now connected to
Home Network 2 and just before I was connected to
My iPhone 3.
The network SSIDs are "Home Network" and "My iPhone" and the suffix gets incremented every so often in my Internet and Sharing Center when I have been disconnected and reconnect. Note that it is not the SSID that changes, but the network name in the Internet and Sharing Center.
Also it asks me every time whether this is a home, office, or public network. What can I do to make it reconnect to an existing network rather than create a new duplicate with a number suffix?
