To configure channels on the Linksys RE6400 Device
 
If you are living in a densely populated area, interference could very well be present affecting your WiFi signals. The lowering of WiFi signals can very much hamper your work. Hence starting with a simple process, locate settings on your device for the ‘Automatic’ selection mode. This would avoid complications in working the device, which would also assist in the Linksys RE6400 Setup. Do check that you can thoroughly follow the device manual. For maximum WiFi range, the 2.4GHz band can be chosen first, followed by channel selection between 1, 6, and 11 without overlapping over the channels. Alternatively, you can change to the 5GHz band, which is less interference-prone.
