Helix fi channel

You can login to http://10.0.0.1/wireless_network_configuration.php to reach the wifi config page where you can switch the channel selection from Automatic to Manual and chose your prefer one.

I did a change for the 5Ghz radio to channel 52 to avoid clashing with my neighbor, most cheap wifi router you cannot go to the DFS channel in 5Ghz which give you more channel then the 36-48 149-161.

I was surprise the DFS channels were available, on the Bell router you can only configure 36-48 149-161.

But I suggest you to use 5Ghz, you can configure a different ssid name for the 5Ghz, the 5Ghz is much faster because it supports 802.11ac high speed, you can practically have speed on wifi easily in the 400Mbits/s where in 2.4ghz, it will be almost impossible unless you are alone.

By default, if you configure the wifi out-of-the-box, the same ssid name will be for 2.4 and 5G, but you can change that, only newer ipad or android are smart enough to chose 5Ghz if both radio share the same ssid name.
