Can I reuse the SSID and password from my old Wi-Fi router on the replacement to avoid having to sign in all my Wi-Fi devices? If not why?
Yes you can.Can I reuse the SSID and password from my old Wi-Fi router on the replacement to avoid having to sign in all my Wi-Fi devices? If not why?
Sure. The reason to NOT do it is that you have the opportunity to improve your network security. By changing the password you know exactly what devices (or people) have the password.Can I reuse the SSID and password from my old Wi-Fi router on the replacement to avoid having to sign in all my Wi-Fi devices?

Now that I think about it, even if two WiFi routers have the same SSID and password, it's likely the computer won't reconnect to one or the other because the WiFi router is also likely broadcasting some unique ID, like its MAC address. And the devices connect via that instead of just the name.Tech support from Asus, the company that makes the ET8 mesh router that I am transitioning to said that I will have to sign into resign into every device even if I use the same SSID and password that was used on the old router. That is the reason I posted the question. It is a good point that both routers will need to use the same protection method. I'll check that. Also, checking to see what devices are connected is a good idea. Thanks.
The gist of the thread is it suggests if you add or replace Wi-Fi APs, devices won't automatically connect to it even if it's the only one in range and with the same SSID and password. Also someone did a test and they found out that you can't have multiple (or two in their case) Wi-Fi APs act as a poor man's mesh network. That is, the device won't hop to the other AP until the one it's connected to disconnects, even if the other AP has a stronger signal.So I am too lazy to read that whole post you linked. It is extremely common to have many router/AP all with the same ssid and password. It allows the device to take a very short drop and switch to the other radio device. So someone who had wifi on both floors of their house and they could go upstairs and it should switch. All the wifi router/ap are running indepenently they do not even really know the other routers/ap exist.
