You may need a mesh network or wi-fi extender, depending on how far away and how many walls are between you and your router at any given time.&nbsp;&nbsp;</P> <P>&nbsp;</P> <P>For most appliances, the 2.4 gHz band is preferred.&nbsp; Phones can elect to use whichever band is more stable.&nbsp; I guarantee you will not notice a difference in speed between the 2.4 gHz and 5gHz band for anything.&nbsp; I do find that the 5 gHz band is less stable and shorter range than the 2.4 gHz band (hence why it's preferred for appliances and smart devices).&nbsp; And, you should configure two networks and not combine them.&nbsp; Most smart devices (especially smart plugs) do not have the hardware to figure out which band to be on when the networks are combined.</P> <P>&nbsp;</P> <P>If you continue to have issues, you will need to contact T-Mobile.</P> Sun, 30 Nov 2025 15:27:56 GMT realaud 2025-11-30T15:27:56Z
