Keep the Same Wi-Fi Name and Password on a New Router?
I replaced a Wi-Fi system while trying to keep dozens of devices connected. Reusing the name and password helped, but security settings and the final device check still mattered.
The main takeaway
Reusing credentials can simplify an upgrade, but it isn't a guarantee every device returns. A weak old password or a needed security change may make a deliberate reconnect worthwhile.

Can a new router use the old network name?
Yes, you can often configure a new router with the same Wi-Fi name and password, allowing saved client profiles to reconnect. This February 2023 video tested that idea rather than assuming all my smart-home devices would follow automatically. The administrator password is separate from the wireless credentials, so don't confuse matching a Wi-Fi profile with copying all the router's settings.
Encryption compatibility can change the result
I discussed how a shift between older security modes and WPA3 can affect clients. Matching only the visible name and password doesn't make every other setting match. Confirm the supported wireless security mode on the exact router and devices. Don't preserve obsolete security simply to avoid touching a few clients; decide whether this upgrade is the right moment to improve the credentials and encryption.
What my device count showed
At the end of the test, the app's online and offline entries accounted for 33 of the 34 devices I was checking, leaving one to identify. The count also changed as devices appeared online and offline. That's a useful reminder to verify the devices you actually rely on—doorbells, hubs and automations—not just declare success because a phone joined the new network.
When I'd reconnect deliberately instead
If the old passphrase is weak or widely shared, keeping it can carry the old problem into the new setup. I discussed choosing a stronger passphrase and using guest access appropriately instead of giving visitors the main credentials. Plan the migration, record device names and test the important functions afterward. Reusing a profile is a convenience option, not a substitute for checking the new network's security and behavior.

Will every device reconnect with the same name and password?
Not necessarily. Encryption compatibility and other settings can affect individual clients.
Did all devices return in Steve's test?
The final checked count accounted for 33 of 34, so one still needed identifying.
