Changing the giga Hertz channel on a router box to comply with phone

I have a Google pixel 3 xl, and I am having a problem linking my work camera with the new one home because it only works with 2.5 giga hurtz channels and my router is stuck at channel 5gh

Just need to know if it is possible to switch the channels on my router or on the phone or I just am gonna have to buy a new camera.
