Solved! Go to Solution.
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.
The above solution is sound, however I would like to add a few details:
It's much more convenient to do this using Helix-Fi ( https://helixfi.videotron.com or using the Helix-Fi mobile app ). You can do this from the Connection tab, then going to View Network and Modify. You also don't need to be connected to your network to do this via Helix-Fi (you can do this from Mars as long as you have an Internet connection).
The Channel selection options will only be available on Helix-Fi after the SSIDs have been split between the two bands.
If you are using Helix Pods, it is not possible to separate the networks by band, therefore this solution will not be available. However, the Helix Gateway (like most routers) will typically pick the least congested channel when it reboots.
HI, I'm guessing the interface changed since you posted this comment because under "Connection" (which is now just "connect" and under "see network" and then Edit.... you can only edit the wifi SSID and passwords.... no channel options.
Help! Because everyone is crowding the 155 and the speeds are garbage...
