I've just replaced my wireless router with a Draytek Vigor 2800. I have 4 machines connecting to the Internet via wireless connection. One of these machines will not connect to the router. The machine is running Vista 32bit and Smart Security. The machine tries to connect and reports 'Identifying' on the connection icon, this appears for a short while before it disconnects then the cycle repeats. On another machine with the same OS and security configuration when I first connected with the new router a box appeared with a message asking something about home or public networks (I can't remember the exact message) I think I clicked on home networks. This machine always connects first time. The problem machine never displayed this message. I have disabled the Firewall, Anti-Virus and Anti-Spyware but the machine will not connect. The machine is set to receive its IP address from the router and is on the same workgroup. How can I shut down Smart Security completely to check if I can then connect?
