I recently received a new router from Spectrum. This router is 2.4 and 5g combined. There's no option to split the two bands as there was in the older model. My problem is that our Christmas lights were all connected via WiFi plugs that must be setup on 2.4 but afterwards are fine on 5g. For the life of me I can't figure out how to resolve this other than purchasing 5g plugs. Any smart folks out there ever encounter this and know a work-a-round? Thank you.
