From what I`ve tried I cannot disconnect this connection I CREATED,
screen cap here,

http://screencast.com/t/ZTUxMDQ2O

I tried networking to my vista via my xp pro service pack3, but accidently set up an internet gateway I think,
when I right click the GSL 604T connection and choose disable, or choose disable this network device in the left menu it gives me this dialogue box " it is not possible to disconnect at this TIME. the connection is currently busy with a connect or disconnect OPERATION"...

please help I`m stuck..I turned off my vista, and pulled out the modem router power source, turning off the modem/router. (Dlink brand)

then plugged it in again, this time that G604T internet gateway was gone when I checked my network connections.

I was WRONG, the modem rebooted when I plugged it in and now the internet gateway is there again, but I always had internet access PRIOR to setting up this network gateway which is what is WORRYING me as I do not have any computer EXPERTISE, which is why I am here seeking help, and I am concerned I have opened up my computer to an outside network?

please help
