Hello, we have noticed a lot of lagging on our Chromecast using 2.4Ghz. There is quite a lot of interference in this band but the Chromecast is only 2.4Gz compatible so I cannot move it to 5Ghz.
I have just created a new (2.4Ghz) SSID dedicated to the Chromecast traffic only and it seems to have improved performance a lot.
Can someone please explain how simply creating a new 2.4Ghz SSID only for Chromecast traffic would have improved things ? I would like to understand the technical details.
