Hi
It is hard to believe that an External DSL Modem/Router is not compatible
with an upgrade of Windows.
You might need to try to reconfigure your Wireless settings.
For the purpose of the initial setting disable the new SP2 Firewall, and
enable it after you make it work again.
May be this can Help.
