Automatic channel on WiFi of the Gargoyle – Netgear WNDR3700

In today's article in the series problems and solutions, talk about how to make WiFi channels on automatic in firmware Gargoyle, I installed it on my Netgear router WNDR3700.

Motivation

Who monitors the Skooter Blog know my network works with two routers that are really acting as routers: the Peplink-Balance One and the ASUS RT-AC68U. The Netgear WNDR3700 is my older router, that today takes only the role of a second WiFi access point and switch Ethernet.

For this, I've been using the alternative firmware OpenWRT, in which I was a bridge between the LAN and WAN ports and turned off the DHCP server, so that he can act the way I wanted to, without using the router features.

But, recently I noticed that he was showing some problems, leaving the connected devices without connection. I decided to test a new alternative firmware, the Gargoyle.

At first I thought he wouldn't see me not, but soon saw that he does exactly what I want without complicated settings. There is an option to disable the Internet connection and another that will bridge the WAN to LAN, without complications. Then you need to just turn off the DHCP server.

Issue

The only limitation I found in the Gargoyle is the WiFi access point settings cannot leave the auto channels, as in the OpenWRT. I like this option because the neighbourhood access points also do not appear to have fixed channel, so I prefer that the router itself to evaluate the spectrum and choose the best channel.

Solution

As the Gargoyle doesn't offer this setting in the graphical interface, the way is to implement it via SSH. Just open an SSH connection and enter the following commands:

Soon, with that the Netgear WNDR3700 is already configured to use automatic channels both in the range of 2,4 GHz, as in the range of 5 GHz. The setting persists even after reboots, so I don't have to rework it, unless you need to mess with any settings that stay in the same fabric as the channel configuration.
