Thanks GDkitty, for all your help, esp. as you are not a Rogers employee!!
Yes, I will change my wifi connection from one of the laptops to the CGN2, and then access 192.168....however, is there a manual somewhere with a step-by-step for turning it into AP mode or do I have to call Rogers tech as some of the posts in the forum suggest? Ultimately, at least in the short term, I may leave well enough alone since having the dual wifi has (knock on wood) not caused any connection/speed issues at this point, but I do want to do a proper set up at some point, to ensure long term stability, etc.....
