Hi @HENDERSON_Gill
The actual frequency changes for each Wi-Fi channel. The 2.4GHz band normally goes from 2402MHz up to 2452MHz & in some cases 2462MHz. The 5GHz band on the other hand, goes from 5180MHz up to (depending on which router you have) 5825MHz.
However, from the latter part of your question, do you really mean how do you change Wi-Fi channels in the router? If that is the case, what make/model of router do you have?
