Hi

Make sure the Router is properly placed, it should be put in open area instead of inside a cabinet or shelf.

Login the web management interface of the Router, go to Advanced > Wireless > Wireless Settings, change the wireless channel into another one.

How to login the web management page of the router

For 2.4GHz wireless client devices, adjust 2.4GHz channel width into 20MHz, for 5G wireless client devices, adjust 5GHz channel width into 80MHz or 40MHz to avoid interference.
