2.4 is the older standard of band which is slower but reaches further. 5 GHz is faster at shorter range. However, 2.4 GHz what most smart TV and TV consoles run on. By default, both our routers – Linksys and Ubiquiti offer both bands. With Ubiquiti, 2.4 shows up as a separate network – the same as yours with just 2.4 at the end – which operates on the same password. The 2.4GHz is more prone to interference which is another reason as well as speed why the world’s devices mostly run on 5 GHz.
