Generally speaking, your router uses only one of the fourteen available channels to operate. It is normal that they overlap, but the following channels – 1, 6 and 11 never overlap and this is the reason why they are most commonly used. In some cases when the internet connection is unstable, there are chances that you are experiencing some interference. Change the router channel in the router settings page. To login to the router settings page you have to know the default router IP and login details. In most cases the IP is 192.168.1.1 [1] (Never type 192.168.l.l because this is wrong.)
