Question: can 2.4 ghz connect to 5ghz?
Answer: A 2.4 GHz device can communicate with a 5 GHz device without problem and the converse is also true, the modem will send out and receive both 2.4 and 5 GHz bands. The older 2.4 GHz band is known to transmit a further distance than a 5 GHz, but 5 GHz can transmit data faster for shorter distances.
