Accessing your settings page
Open your web browser and type in 192.168.1.1 in the address bar. This will bring you to the login screen for your router interface. The username and password are both set to ‘admin’ by default (if you’ve changed this, then please enter your specified details).
Changing the channel
Navigate to ‘Wireless’ within the ‘Advanced Settings’ menu on the left-hand side.
Change the ‘Control Channel’ to a less congested channel. You can test which channel is the best for you by running a speed test (over wireless) for each one. Alternatively, a range of free software is available to find the least congested channel.
If you’re using an older device, it may help to improve your wireless connection by changing your ‘Channel Bandwidth’ to 20 MHz. If you’re still suffering from interference, try changing this to 40MHz.
