Ok , I have a lag switch the one made with the orange wire , now
I don't use it a lot since I'm not bad in black ops but I like to be the host of the lobby because it gives me good connection
So I would want a way to get host every time (No wifi)
I've searched a lot about that and I didn't find a Working tutorial so please if u can help me I will appreciate it

You cant be the host whenever you want, the computer or the program in the game chooses a host that has a good connection.
