RS500 - Auto 5 ghz channel setting picks up DFS channel?
My neighborhood is pretty crowded with 5 Ghz channels. The auto 5 Ghz channel selection setting picks up channel 100 which is a DFS channel. This channel also has lower transmit power than the non DF...
Reason for picking a DFS channel is maybe your in range of a Airport and it's radar system. Usually if a router is in around 5 miles of a airport, the router may pick a DFS channel which maybe lower power due to not attempting cause any interferences with Airport and radar. Been like this for a while now. https://en.wikipedia.org/wiki/Dynamic_frequency_selection
The tuning maybe as designed as well for best operation for Auto mode. If your using Auto channels, then you have the ability to manually set different channels. Recommended are 1, 6 and 11 on 2.4Ghz and 40 thru 48 or 149-161 on 5Ghz.
You can submit a support ticket to NG to make them aware of your concerns.
Yes, but anytime a DFS channel might get kicked out due to interference if any radar is detected in the future. In my testing manual channel 44 or 153-161 gets the best signal strength and range. Even when using the auto DFS channel selection, the DFS channel transmit power is lower than say channel 44 or 161.
Another observation is when using channels 149-161 and the speed set to 5.8 Gbps, most older wifi 5/6 clients don't get their maximum speed in the 5 Ghz band. My intel AX203 card only gets 300 Mbps when the router channel is set to 161 and speed set to 5.8 Gbps. How can I pass this along to NG?
