Slow Wi-Fi Speeds... Shouldn't Videotron provide DFS-enabled routers where required?

On the 5GHz band, I'm looking at speeds of around 5Mbps (less on the 2.4GHz band) on a 120Mbps connection when I'm less than 10m away from my router. But with so many networks in my area running on the same frequency bands... I'm not surprised. I would really like to see Videotron provide routers with DFS support in areas where they are required to provide effective service. You really can't call these routers "Cutting Edge" if I have no choice but to buy a new router with DFS support to provide effective WiFi coverage for my home.

Good morning brennann,


The Zyxel router that is provided by Videotron is equipped with the automatic channel search option. This will allow the router to use the channel with the least interference in your area.It's the equivalent of the DFS support. It is also possible to disable this option if you wish to manually select a channel and use a Wifi analyser tool that you can download on your phone, computer or tablet. 


For more details on this feature, please refer to your user guide downloadable from this page:;


If slowness persists, I suggest you contact technical support for a global checkup. 


I probably should have been more specific in my original post. 


I have used a WiFi analyzer tool -- which is why I know so many networks in my area are running on the same network channels. On the 5Ghz band, there are several networks on channels 36-48, and several other networks on channels 149-165. You'll note that these are the only channels the Zyxel router is licenced to operate on ( Thus, it is not possible to select a channel that does not interfere with other networks in my area. 


By DFS support, I was refering to the routers ability to broadcast on channels 50-64 and 100-144 where DFS support is legally required. There are no networks in my area broadcasting on these channels. Note that the Zyxel router is not licenced to operate on these channels ( Realistically, the only way to solve this issue is to configure my network to use the 'DFS channels'... which is not possible with the Zyxel router. 


P.S. There are even more networks running on the 2.4 GHz band... so switching over is not a solution.
