What happens if 2.4GHz and 5GHz have the same SSID?

I keep the same SSID. The default settings on my OC200 seem to auto-distribute my clients across the 5.8G and 2.4G bands pretty evenly. I've basically never ...

In my experience, it's better to have a unique SSID per radio, because devices that support both 2.4GHz and 5GHz radios will connect to the SSID with the ...

Simply naming the two SSIDs differently does nothing to actually apply that 2.4GHz vs. 5GHz separation.

Setting the same SSID and password for both network configs (2.4 and 5) indeed enables 2.4Ghz only devices to connect to Wifi while 5Ghz devices connnect over ...

I have recently changed my wifi router and on this one, it seems I have to have the same SSID name for the 2.4GHz and the 5GHz networks.

The best practice is to have separate SSIDs, with frequencies chosen to match the device and the task at your hand.

Yes, 5GHz tends to be faster, but 2.4GHz has better range. If you use the same SSID then your client can automatically switch from 5 to 2.4 when ...

The advantage of using the same SSID is that your devices can roam between 2.4Ghz and 5Ghz and pick what they use. It is easy to set up on your ...

Using the same SSID on both bands can help devices stay connected, especially in areas where 5 GHz can't reach but 2.4 GHz can.

Always use same SSID. The only disadvantage is that in some case, some extremely badly designed cheap IoT will have problems less to connect.
