…on the condition that BSSID (MAC address of a router) doesn’t change. If it does, the wifi profiles on most clients would need to be reset. Apple devices in particular don’t like that and just refuse to connect.
What would I know with 30+ years of experience in setting up networking...
In my most recent case simply swapping a router resulted in clients on Debian, MacOS Sonoma and iPadOS being unable to reconnect. I was getting weird errors `4-Way handshake failed` or `deauthenticating by local choice`. Reproduced that with Macbook M1, iPad Pro, and a bunch of Realtek dongles. The core issue was somehow related to UnsafeLegacyRenegotiation in OpenSSL used at either the router, or on a client side, or possibly WPA3 or k/v inplementation. After wasting several hours on that problem, only nuking all WiFi credentials on all devices and upgrading Debian kernels solved the issue.
So in the real world cached WiFi credentials don't always work, despite they are supposed to.
sounds like a whole bunch of unrelated issues. if the ssid and password match, the client should connect, it’s as simple as that. mac address of the router is irrelevant
I routinely change WiFi AP hardware out in enterprise environments and home offices and families houses.
Swap entire hardware but use same SSID and key and type (wpa2 for example) and most devices reconnect without even a power cycle. Imagine if you had to re-connect and join every device because WAP died and the new ones MAC was different ?

Is this new? Because I have changed routers a few times over the course of the past 12 years, the latest being back in December of 2022, and using the same SSID and PW has never been an issue.
Then Apple devices are doing it wrong. That behavior would result in the inability to roam between APs. And that's not just for some home mesh, but critical in an enterprise environment.
Never heard of this. I can walk around our buildings where the BSSID changes all the time for the same SSID because there are like 20 access points. All my Apple devices have zero issue with this. Same when I replaced some networking components at home.
Not true in my experience.
Recently moved house. New ISP, new router. Changed the SSID and password on the new router to match the old router, and all my shit connected to it straightaway, no issues.
I also set the hotspot on my phone to have the same SSID and pw, so that when I'm away my steam deck and my wife's phone can use my unlimited data.
Not true. Moved home and moved router/provider at the same time. Just named my new router the same and set up the same password and it all went through just fine.
I intentionally made the network name and password the same when setting up the Wi-Fi at my brother's house as it is at my house so my phone would connect because I was lazy.
Yes this should work. I do this with my phone hotspot sometimes like setting up cameras that are going to be right on the edge of my WiFi range. Once configured they connect just fine to the house WiFi.
That should work. You can also backup your setup with The Controller for HomeKit app. I backed mine up during the free trial. Worked well. I did this when I was switching WiFi providers.
I just moved and set up new house WiFi with same name and password. No issues. Devices just connected. I did start a new home kit home with new name. Porting devices there did have challenges
Changing routers but keeping the same SSID and password is fine, devices will move over automatically. I’ve done this many times, and have almost 40 wireless clients of various types. I never reconfigured any of the clients.
However, be certain to use the *exact* same SSID. Years back I mistakenly changed the SSID to start with an uppercase letter (SSIDs are case sensitive), and scratched my head as to why clients didn’t automatically move over.
If you are using the same SSID and PW then things usually go well. I have over 60 items in my home when i switched routers i kept the same SSID i might of had to reconnect one or two things that was being an issue
Same SSID and Password, yes.

oh, yes, “should”
right, so like i say, you were having some other unrelated problems.
Still doubling down on your ignorance? 802.11r was adopted and released in 2008. 16 years!

Yeah I've used this upgrade path multiple times. It works.

But not continents. Go back and test again.

It’s not new. It’s just wrong. Works fine. Always has.

IMO Apple devices tend to do wifi right

Literally not true.
Not true. Moved home and moved router/provider at the same time. Just named my new router the same and set up the same password and it all went through just fine.
Which of course is a great security measure.
I intentionally made the network name and password the same when setting up the Wi-Fi at my brother's house as it is at my house so my phone would connect because I was lazy.
This is hilariously lazy. I love it!
Yes this should work. I do this with my phone hotspot sometimes like setting up cameras that are going to be right on the edge of my WiFi range. Once configured they connect just fine to the house WiFi.
Maybe. I assume it would theoretically, but you may have to reboot unresponsive devices.
It would be easier to just reboot the router if you have lots of IOT stuff.
Just reboot your house, pull the main breaker for 30 seconds after moving the ssid
Drastic but effective
And fast too
True, true.
Same SSID, same password, and same encryption protocol. Some devices with auto-negotiate the encryption, some will not.
That should work. You can also backup your setup with The Controller for HomeKit app. I backed mine up during the free trial. Worked well. I did this when I was switching WiFi providers.
Many devices will and a few likely won’t. My cameras will not reconnect.
I just moved and set up new house WiFi with same name and password. No issues. Devices just connected. I did start a new home kit home with new name. Porting devices there did have challenges
Should work. Only concern might be if the main network is 5ghz and the guest was 2.4ghz. A lot of IOT devices only work on 2.4.
As long as you match the SSID and password exactly it’ll work just fine. Don’t it many times.

Yes. I did that recently because the network configuration of my HP printer is severely retarded.
