So I have a Arris TG862g from Xfinity and for some reason it wont connect to my Xbox360 slim. I read in some places that you have to change it from WAP2 or something to WAP. I'm not too tech savvy and I don't know how to do that. Some people said that you also have to change the parental settings. And even when it does connect to the internet there is too much lag and sometimes it drops me out of a match. Any help?
