The clients are smart enough to choose the correct one. If you are behind a lot of walls, it will connect to 2.4ghz. If you are near by, it will take 5.8ghz. Some clients will swap when the signal levels change. Depends on the device. In windows you can check the wifi status to see which one it connected to, same on a smart phone in wifi info.
Well, I tried it and everything seems to be working. I had to restart a desktop PC to get it to connect. I renamed my 5G to match the 2.4G. Everything is connected to the 2.4G except one Android. Your suggestion helped me simplify my network setup.
quick suggestion if I may -
since a single SSID for both radios is the common use-case on modern equipment,
isn’t it better to have the default SSIDs to be the same on the gl-inet firmwares?
this would simplify things for users that are not familiar with the subject
As Alfie wrote new routers now have the same SSID, i think that is the way it will be for new products from now on Alfie can confirm, but since old routers already have labels printed and settings set, it’s not ideal to just change it in future firmware for those products, it would cause confusion.
