Just found out that my neighbour can access my ISP via my wireless 802-11g connection. And I can access via his connection...Not a good situation.
I have checked security settings in both my router and Windows 7 network connection.
I have checked that WPA2-PSK security and AES encryption is selected and a 8 digit network security key is current.
I have disabled sharing. When connecting the network does not ask for a network security key but connects instantly and functions correctly
I can see but cannot connect to another neighbours connection because it asks for a network security key and I do not have it.
I will appreciate any advice.
