R8000 Nightwawk: Can not enable wifi - 5G network only offers DFS channels

Question

Latest firmware&nbsp;V1.0.4.76_10.1.82Location: Europe&nbsp;I wasn't using Wireless&nbsp; on the R8000 for a very long time. Today I tried to turn it ON but I got the infamous "This DFS channel is not allowed to use because the Radar was detected before. You can change another channel or wait" error.&nbsp;I scratched my head, then browsed some forums and understood what DFS is and that it might create some issues here (I live near an airport).&nbsp;Ok so, I don't need it, let's just select a non DFS channel - but this is what I get in my settings:&nbsp;&nbsp;&nbsp;My 5G-2 wireless network only allows DFS channels!&nbsp;&nbsp;Any ideas on how can I fix this? How can I just disable 5G-2?Everything I tried so far to turn back on WiFi ends up with the above mentioned "DFS/Radar" error!&nbsp;&nbsp;PS: a factory reset is unfortunately not possible as there are too many settings I could not lose (first of all: the&nbsp;Address Reservations managed by the R8000 as the DHCP service)&nbsp;&nbsp;&nbsp;&nbsp;

Not sure what you mean but thanks for trying to help!&nbsp;I'm using the R8000 as a router. It is not configured as a stand-alone wireless AP.&nbsp;What setting could I check to answer your question?

For your speed. In the photo, the box is obscured. If its set at "up to..." certain rate, maybe its only allowing those channels used because its to wide. You can try setting the speed mode down.&nbsp;

It's set to "Up to 1300 Mbps", but even if I set it to the lowest "Up tp 289 Mbps" the available channels remain the same - only DFS
