I need to upgrade the router but I also have multiple cameras (Nest and Blink) as well as TVs all using the current router. I have been assured that upgrading the router itself is no big deal but....

If I change the SSID and the passwords to be identical that the current set up, will the cameras (some of which are difficult to get to) be able to seamless access the new router.

Any guidance or assistance on this would be appreciated. Thank you.
