I got the package deal with comcast that has TV,internet and phone, their modem/wifi router is freaken me out. I set up my secured connection but I noticed another connection thats open for all to log onto (they say my network is safe) They tell me its separate but they could soak up my bandwidth. Does anyone know how to turn this second signal off? If I had known this I wouldn't have gotten the phone option and just used my own wifi router
